   2
   3         Get rid of options member variable in Benchmark.
   4
   5         Options are only needed when initializing the stage or benchmark, so there's no
   6         need to also keep a reference to it.
   7
   8         * Animometer/tests/resources/main.js: Get rid of options variable in Benchmark.
   9         Pass options to Controllers and Stages.

  36
  37         Update how the benchmark is run
  38         https://bugs.webkit.org/show_bug.cgi?id=153960
  39
  40         Provisionally reviewed by Said Abou-Hallawa.
  41
  42         Introduce the notion of a Controller. It is responsible for recording, updating,
  43         and processing the statistics and complexity of the benchmark. This allows
  44         plugging in different Controllers.
  45
  46         This strips most of the functionality from Animator and BenchmarkState, so fold
  47         what's left into Benchmark. Now, Benchmarks only own a stage and a controller, but
  48         are responsible for driving the animation loop.
  49
  50         Rewrite Animator._shouldRequestAnotherFrame into two different Controllers. One
  51         maintains a fixed complexity, and the other adapts the complexity to meet a
  52         fixed FPS.
  53
  54         Fix the Kalman estimator to be modeled on a scalar variable with no model.
  55
  56         * Animometer/tests/resources/main.js: Remove BenchmarkState and Animator, and
  57         replace it with a Controller. Add a FixedController and refactor the previous controller
  58         to an AdaptiveController.
  59
  60         (Controller): Controllers own the estimator and the sampler. When a new frame is
  61         displayed, the animation loop calls update(). The estimator and sampler record
  62         stats, then tune. Samplers can track multiple series of data. The basic controller
  63         tracks timestamp, complexity, and estimated frame rate.
  64                 The Kalman estimation is based on the frame length rather than the frame
  65         rate. Because FPS is inverse proportional to frame length, in the case where the measured
  66         frame length is very small, the FPS ends up being a wildly large number (in the order of
  67         600-1000 "FPS"), and it pulls the estimator up drastically enough that it takes a while
  68         for it to settle back down. Using frame length reduces the impact of these spikes.
  69                 Converging the estimation takes enough time to avoid initializing it immediately
  70         when the benchmark starts. Instead, the benchmark runs for a brief period of time (100ms)
  71         before running it in earnest. Allow controllers an opportunity to set the complexity
  72         before starting recording.
  73                 When the benchmark is complete, the controller has an opportunity to process
  74         the samples. The default implementation calculates the raw FPS based on the time
  75         difference of the samples, and calculates the complexity score. This is moved from
  76         Benchmark.processSamples.
  77
  78         (Controller): Initialize timestamps. These are at first relative to the start of the
  79         benchmark, but are offset by the absolute start time during start(). By default maintain
  80         3 data series, but subclasses can override.
  81         (start): Calls recordFirstSample() for subclasses to override if needed.
  82         (recordFirstSample): For basic controller, start sampling at the beginning.
  83         (update): Update the frame length estimator and sample.
  84         (shouldStop): Checks that the time is before _endTimestamp.
  85         (results): Returns the processed samples.
  86         (processSamples): Iterate through the sample data and collate them. Include scores.
  87
  88         (FixedComplexityController): Controller that tunes the stage to the desired complexity
  89         prior to starting, and keeps it at that complexity.
  90
  91         (AdaptiveController): Have the estimator estimate the interval frame rate instead of the
  92         raw frame rate.
  93                 The previous version of this controller ignored the frame that came after the
  94         adjustment. The raw FPS show that whatever noise the scene change adds is negligible
  95         compared to the noise of the system overall. Stop ignoring that frame and include all
  96         frames in the measurements.
  97
  98         (Benchmark): Remove dependency on animator, and instantiate a runner based on what is
  99         selected. Most of the loop's functionality is in Controller, so remove here.
 100         (Benchmark.run): Remove start() since it is only called from run(), and fold it in here.
 101         (Benchmark._animateLoop): Fold in from Animator.animateLoop. Let the benchmark run for
 102         a brief period before calling Controller.start().
 103
 104         * Animometer/tests/resources/math.js: Fix the Kalman estimator. The filter estimates
 105         a scalar variable, and makes basic assumptions regarding the model. As a result
 106         none of the linear algebra classes are needed, so remove Matrix, Vector3, and Matrix3.
 107         (SimpleKalmanEstimator): Calculate the gain based on the provided process and
 108         measurement errors.
 109         (KalmanEstimator): Deleted.
 110         (IdentityEstimator): Deleted.
 111         (PIDController): Refactor to use the Utilities.createClass() helper.
 112
 113         The Kalman filter algorithm is explained here http://greg.czerniak.info/guides/kalman1/.
 114         The state, represented by a scalar, is the estimated frame length. There is no user
 115         transition of the state, and the state is the same as the measurement. With this model,
 116         the estimation error converges, so calculate the gain ahead of time.
 117
 118         * Animometer/developer.html: Remove fixed-after-warmup since it is not useful.
 119         Replace the option to toggle the estimator, and make it possible to customize the
 120         estimator's error parameters. Show raw FPS by default, and remove interval FPS,
 121         which will be shown instead of the filtered raw FPS.
 122         * Animometer/resources/debug-runner/animometer.css: Put the header behind the graph.
 123         Remove #intervalFPS rules; move the color to #filteredFPS.
 124         * Animometer/resources/debug-runner/graph.js:
 125         (updateGraphData): Update the hr style to force the layout to be calculated
 126         correctly. Change the tick format to be in terms of seconds, since the timestamps
 127         are in milliseconds. Remove interval data.
 128         * Animometer/resources/runner/animometer.js:
 129         (window.benchmarkController.startBenchmark): Set Kalman parameters.
 130         * Animometer/resources/runner/benchmark-runner.js:
 131         (_runBenchmarkAndRecordResults): When a benchmark completes, expect it to return
 132         the final data, rather than passing a sampler from the controller. This avoids
 133         needing to expose the sampler variable in the benchmark.
 134         * Animometer/tests/resources/sampler.js:
 135         (process): Move the setting of the target frame rate to AdaptiveController.
 136
 137 2016-02-06  Jon Lee  <jonlee@apple.com>
 138
 139         Code clean up: Move Rotater function closer to Stage static methods.
 140         The Rotater is used together with those methods; keep them close.
 141
 142         * Animometer/tests/resources/main.js:
 143
 144 2016-02-06  Jon Lee  <jonlee@apple.com>

 153         Move createElement and createSVGElement to Utilities.
 154
 155         * Animometer/resources/extensions.js:
 156         (Utilities.createElement): Added.
 157         (Utilities.createSVGElement): Added.
 158         (DocumentExtension.createElement): Deleted.
 159         (DocumentExtension.createSvgElement): Deleted.

 168
 169         Add a convenience function for creating a class.
 170
 171         The pattern for creating a class is common enough to add as a Utilities
 172         helper function. It also makes it easy to collapse class definitions when
 173         editing.
 174
 175         * Animometer/resources/debug-runner/animometer.js: Move ProgressBar definition,

 211         (window.suitesManager._onChangeTestCheckbox): Refactor to take a checkbox.
 212         (window.suitesManager._createTestElement): Enhance such that typing into the complexity
 213         input will automatically select that test for running.
 214         (window.suitesManager.updateLocalStorageFromJSON): Make the harness work for private
 215         browsing.

 220
 221         Refactor helper methods for getting random values for a stage.
 222
 223         Instead of requiring a Stage instance, just attach it to the Stage object.

 290
 291         Reviewed by Simon Fraser.
 292
 293         Add a new test. The test has a rotating background
 294         gradient, and does a better job physically simulating
 295         particles.
 296
 297         * Animometer/resources/extensions.js: Teach Point to take constants as well as other Points.
 298         (Point.prototype.length): Added.

 371         Add a waitUntilReady() callback that lets the benchmark complete
 372         its setup before running the benchmark.
 373
 374         * Animometer/tests/resources/main.js:
 375         (Benchmark.prototype.run): First call waitUntilReady, which returns
 376         a promise. When the promise resolves, run everything that was in this
 377         function.
 378         (Benchmark.prototype.waitUntilReady): Default implementation returns
 379         a resolved promise.
 380         (Benchmark.prototype.resolveWhenFinished): Deleted.

 386         Update data reporting and analysis
 387         https://bugs.webkit.org/show_bug.cgi?id=152670
 388
 389         Reviewed by Simon Fraser.
 390
 391         Show new graph data. Provide controls to show different series data. Provide an
 392         interactive cursor that shows the data at a given sample.
 393
 394         * Animometer/developer.html: Add a nav section in #results. Each part of the graph
 395         has a checkbox for visual toggling, as well as companion spans to contain the data.
 396                 The numbers will always be shown even if the SVG isn't.
 397         * Animometer/resources/debug-runner/animometer.css:
 398         (#suites): Adjust spacing when doing fixed complexity.
 399         (#test-graph nav): Place the nav in the upper right corner.
 400         (#test-graph-data > svg): Fix the FPS scale from 0-60. It makes the raw FPS goes past
 401         that scale. Allow it to show.
 402         (.target-fps): Add a dotted line for where the benchmark is supposed to settle for FPS.
 403         (#cursor line): The cursor contains a line and highlight circles for the data being shown.
 404         (#cursor circle):
 405         (#complexity path): This and rules afterward are named by series type.

 412         (.right-samples): Deleted.
 413         * Animometer/resources/debug-runner/animometer.js:
 414         (initialize): Add a "changed" listener when the checkboxes change in the nav.
 415         (onBenchmarkOptionsChanged): Renamed.
 416         (showTestGraph): All graph data is passed in as graphData instead of as arguments.
 417         * Animometer/resources/debug-runner/graph.js: Extend BenchmarkController. When showing
 418         a new graph, call updateGraphData(). It creates all of the d3 graphs. onGraphOptionsChanged()
 419         toggles the data on and off.
 420         (updateGraphData): Add the axes. Add the average lines and markers for sample time and
 421         target FPS. Add the cursor group. Use helper function addData() to add the data. On top of
 422         everything add a transparent area which will catch all of the mouse events. When the mouse
 423         moves in the graph, find the closest data point, show the data in the nav area, and highlight
 424         the data points.
 425         (addData): Adds a line and circle for each data point. Also adds a highlight cursor with a
 426         size a little larger than the circle radius for the data points.
 427         (onGraphOptionsChanged): Called when data is visually toggled.
 428         (showOrHideNodes): Helper function to toggle the .hidden class.
 429         * Animometer/resources/extensions.js:
 430         (ResultsDashboard.prototype.get data): Get rid of the arguments for _processData.
 431         (ResultsTable.prototype._addGraphButton): Shove all of the graph data into a singular object.
 432
 433         Producing the JSON can take a while with all of the data. Make it on-demand with a
 434         button.
 435
 436         * Animometer/resources/debug-runner/animometer.js:
 437         (showResults): When showing the results, don't serialize the JSON data. Move that to...
 438         (showJSONResults): ...here. Remove the button.
 439
 440         * Animometer/developer.html: Add a button. The button will remove itself and populate
 441         the textarea with the JSON data.
 442         * Animometer/resources/debug-runner/animometer.css:
 443         (.hidden): Add a universal hidden class.
 444         (#results button.small-button): Promote the small-button styles to the whole results
 445         section for use in the JSON button.
 446         (#results button.small-button:active):
 447         (#results-data button.small-button): Deleted.
 448         (#results-data button.small-button:active): Deleted.
 449
 450         Refactor how Animator does its recording.
 451
 452         * Animometer/tests/resources/math.js: Create a new, simple estimator that just returns
 453         the same interval frame rate for adjustment.
 454         * Animometer/tests/resources/main.js:
 455         (Animator): Remove _dropFrameCount, and make variables more accurate described.
 456         (Animator.prototype.initialize): Use the identity estimator instead of using a bool.
 457         (Animator.prototype._intervalTimeDelta): Rename, only used internally.
 458         (Animator.prototype._shouldRequestAnotherFrame): Assume we drop one frame for adjustment
 459         of the scene. If we are within the number of frames to measure for the interval, just
 460         record the timestamp. Otherwise we are ready to evaluate and adjust the scene. Record
 461         the interval frame rate and the estimator's frame rate.
 462
 463         Avoid processing the data through the Experiment while the test is running. Reconfigure
 464         the sampler to just record the raw samples. After the test is done, run the samples through
 465         the Experiment to get the score.
 466
 467         * Animometer/resources/sampler.js:
 468         (Experiment): Fold _init() into the constructor since nobody else will call it. This is not
 469         needed until the test concludes, so remove startSampling(). Clients should just call sample().
 470         (Sampler): Pre-allocate arrays given the number of data points being recorded, and a capacity
 471         of how many samples will be used. The processor is a called when it's time to process the data
 472         since that is the client also telling the Sampler what to record.
 473                 Introduce the notion of marks as well, which allows the client to mark when an
 474         event occurs. When we mark sample start, we can attach the timestamp there, instead of storing
 475         it separately.
 476         (Sampler.prototype.startSampling): Deleted. Clients should just call record().
 477         (Sampler.prototype.record): The data to record is passed in as variable arguments.
 478         (Sampler.prototype.mark): When adding a mark, a client needs to provide a unique string, and
 479         can provide extra data object for later retrieval.
 480         (Sampler.prototype.process): Renamed from toJSON. Trim the sampling arrays to what was used.
 481         Call the processor to process the samples.
 482         * Animometer/resources/debug-runner/benchmark-runner.js:
 483         (BenchmarkRunner.prototype._runBenchmarkAndRecordResults): Call process().
 484
 485         * Animometer/resources/strings.js: Add some new strings, remove the graph ones since they are
 486         not used.
 487         * Animometer/tests/resources/main.js:
 488         (Benchmark): Create a sampler with 4 series. The maximum number of points expected is the
 489         number of seconds multiplied by 60 fps. Benchmark, as a client of the Sampler, knows about all
 490         of the data being added to the Sampler. It is added through record(), and processed through
 491         processSamples().
 492         (Benchmark.prototype.update): Mark when we've passed warmup and are starting to sample. Include
 493         the timestamp in the custom data for the mark. This avoids the need to store is separately in
 494         the Sampler. Fold what was in record() here, since nothing else needs this functionality.
 495         record() now just relays the information to the sampler.
 496         (Benchmark.prototype.record): Called by Animator, which provides the data to the sampler.
 497         Animator's calls to this is part of a later patch. Requires each stage to return its complexity.
 498         (Benchmark.prototype.processSamples): If the sampling mark exists, add it to the results.
 499                 Go through all of the samples. All samples contain a timestamp and complexity. We
 500         calculate "raw FPS" which is the time differential from the previous sample. At regular intervals
 501         the Kalman-filtered FPS and the interval average FPS are also recorded. We also create two
 502         experiments, to get the scores for the complexity and smoothed FPS, and add those samples to
 503         the experiments. Grab those scores and add them into results also.
 504
 505         Add complexity() to the tests for Benchmark.record().

 517
 518         Update the simple canvas tests. For the paths, start from the center instead of the
 519         top-left corner. Instead of using a coordinate limit, use a canonized factor, and
 520         use that along both the x and y axes, so that more capable tests use more of the
 521         canvas.
 522
 523         * Animometer/tests/simple/resources/simple-canvas-paths.js:

 679         * Animometer/tests/resources/main.js: Messages are no longer needed
 680         (Animator.prototype._shouldRequestAnotherFrame): Rename from animate(), since this method returns a boolean
 681         indicating whether another frame should be requested. Collapse the logic from StageAnimator into animateLoop.

 694
 695         Make the class relationships more easily understandable. The benchmark owns the stage,
 696         animator, and options. Make the stage and animator no longer have their own references to
 697         the options. Make Stage a first-class citizen by promoting it to main.js. Later patches

 708         them.
 709         (Benchmark.prototype.get options):
 710         (Benchmark.prototype.get stage): BenchmarkStates.stages will need to be renamed to avoid confusion.

 712         (Benchmark.prototype.start):
 713         (Benchmark.prototype.update): Ask the stage directly to tune or clear instead of adding another
 714         level of indirection.
 715         (window.runBenchmark): Deleted. Remove the need for a benchmarkClient. Also remove the standalone
 716         path, since tests can be individually selected, and remove the need for runBenchmark since that is
 717         handled in BenchmarkRunner._runBenchmarkAndRecordResults.

 729         * Animometer/tests/master/resources/canvas-tests.js: SimpleCanvasPathStrokeStage is no longer needed.
 730         (CanvasLineSegment.prototype.draw):
 731         (CanvasArc):
 732         (CanvasLinePoint): Remove the draw call because depending on its index it either needs to be moveTo
 733         or lineTo, and it is otherwise a very small draw operation that doesn't need the overhead of the
 734         function call. Do all of the drawing through the stage.
 735
 736         Refactor the subclass pattern. Introduce Utilities.createSubclass().

1007         to results and make it accessible for other objects to use.
1008         (willAddTestFrame): This is unnecessary. Remove.

1031         need for an empty children array. This was to allow for a header row in the table that spanned
1032         multiple columns. In the simpler harness, this is not needed.
1033         (ResultsTable.prototype._showEmptyCells):
1034         (ResultsTable.prototype._showTest): This hardcoded the columns. At least for the name and score,

1036         * Animometer/resources/runner/animometer.css: Added. Use a similar 2:1 ratio. The score tables are
1037         split into the data and the headers, and are also displayed RTL so that a later patch allows a
1038         user to copy-paste the data easily.
1039         * Animometer/resources/runner/animometer.js: Added. Use a simpler version of benchmarkRunnerClient.
1040         The debug harness will extend these classes.
1041         (window.benchmarkController._startBenchmark): Used by both harnesses.
1042         (window.benchmarkController.startBenchmark): Set hard-coded options.

1814
1815         The existing code incremented this._frameCount after checking against this._dropFrameCount.
1816         This has the effect of setting this._measureTimeOffset one frame too late, so
1817         we were measuring only two frames, not three, and thus computing an incorrect fps.

2045         into one long path, and tries to render that one path. Random points make it
2046         difficult to tell what is going on, so add a parameter to the constructor to
2047         confine the area where the random coordinates can land. The more complicated the
2048         case is, the larger an area the path will cover. Add an artificial minimum so
2049         that the first 200 points aren't confined to a space that is too small.

2233         Instead of measuring the FPS of the animation, this benchmark measures the
2234         test complexity when rendering at a set-point FPS which should be lower
2235         than 60 FPS. This benchmark tries to stay at the set-point FPS by using
2236         a closed loop control system PID function. The gain of the system is passed
2237         as a parameter when running the test. Measuring the FPS faithfully results
2238         very fluctuating values. A Kalman filter is used to give a better estimate
2239         for the current FPS.
2240
2241         The animation of the tests is done manually. requestAnimationFrame() is
2242         called with a callback. Inside this callback, the test is animating by
2243         changing the positions of the elements inside the page. The test complexity
2244         may change also if the current FPS is not equal to the desired FPS.

2833         [JetStream] Raise the percentile of mandreel-latency and splay-latency
2834         https://bugs.webkit.org/show_bug.cgi?id=146378
2835
2836         Reviewed by Mark Lam.
2837
2838         The current percentile is 95%.  When I looked at the sample lists in our GC, it was
2839         clear that the worst 5% samples completely amortize our GC pauses.  Our GC pauses can
2840         be quite bad.  Clearly, splay-latency is meant to test whether we have an incremental
2841         GC that ensures that you don't have bad worst-case pauses.  But 95% is too small,
2842         because it doesn't really capture those pauses.  Raising the percentile to above 99%
2843         appears to do the trick.  99.5% or more seems like a good bet.  The trade-off there is
2844         just that if we set it too high, then we won't have enough statistics.  Doing this very
2845         clearly rewards GCs that are incremental, and punishes GCs that aren't (like ours).
2846         That's what we want, since in the future we want to use this test to guide any
2847         improvements to the worst-case performance of our GC.
2848
2849         The way that the percentile is selected will also affect mandreel-latency.  That's a
2850         good thing, because 95% is probably too low for that test as well.  That test ends up
2851         with >10k samples.  The goal of using 95% in the first place was to get enough samples
2852         to have a stable average.  But if we have >10k samples, we can push that percentile up
2853         much higher and still get good statistics while achieving the effect we want - i.e.
2854         getting the worst case.
2855
2856         I don't think that we need to do the same thing for cdjs.  That test only takes 200
2857         samples, so 95% means we report the average of the worst 10 samples.  That's probably
2858         good enough.
2859
2860         * JetStream/Octane2/base.js: Raise the percentile as described above.
2861         (BenchmarkSuite.prototype.RunSingleBenchmark):

2885         JetStream should include a JavaScript version of the CDx real-time benchmark
2886         https://bugs.webkit.org/show_bug.cgi?id=146156
2887
2888         Reviewed by Geoffrey Garen.
2889
2890         This adds a JavaScript port of the CDx real-time benchmark to JetStream, and retires
2891         the cordic test because it was previously the smallest and probably least interesting.
2892
2893         The new test, "cdjs", is mostly a faithful rewrite of the Java code into JavaScript.
2894         I got the Java code from https://www.cs.purdue.edu/sss/projects/cdx/.
2895
2896         There are some differences:
2897
2898         - It uses RedBlackTree's for all sets and maps rather than hashtables. This is clearly
2899           more in the spirit of real-time than the CDx benchmark. FWIW, CDx used to use trees
2900           and I don't know why that changed in the latest version.
2901
2902         - CDjs doesn't attempt to avoid memory allocations, unlike the real-time Java version.
2903           I wrote the code that I wanted to write for aesthetics, rather than the code that I
2904           would have written if I tried to write the fastest code possible. Again, I believe
2905           that this is in the spirit of CDj - it's meant to test what would happen if you wrote
2906           real-timey stuff in a high level language and actually took advantage of that
2907           language to be more productive.
2908
2909         The test score reflects the average latency of the worst 10 samples out of 200 samples.
2910         The simulation uses 1000 aircraft, flying along paths that result in some detected
2911         collisions every once in a while. The benchmark validates its results by checking the
2912         total number of collisions detected.
2913
2914         Apart from the integration into the JetStream harness, the CDjs directory contains a
2915         fully self-contained benchmark that could be run either in the jsc shell or in browser.
2916
2917         This new code uses the same 3-clause BSD license as the Purdue code, and gives
2918         attribution to Purdue in almost all files. I believe that is appropriate since I wrote
2919         most of the JS files by looking at the Purdue Java code and trascribing to JavaScript.
2920         In some cases, I even copy-pasted the Java code, like the complicated math for
2921         four-dimensional intersections and voxel hashing.

3020         JetStream should have a more rational story for jitter-oriented latency tests
3021         https://bugs.webkit.org/show_bug.cgi?id=145762
3022
3023         Reviewed by Geoffrey Garen.
3024
3025         JetStream has some latency tests that are meant to measure jitter.  Prior to this change, they
3026         did this by computing the RMS.  But the RMS is a pretty bad metric.  The thing that it rewards
3027         isn't really the thing that you'd want your browser to do.  These RMS-based tests involve taking
3028         the geomean of the RMS of some samples and the sample average.  The lower the geomean, the better
3029         (in the JetStream harness we then invert the scores so that higher is better, but let's ignore
3030         that for this discussion and assume that lower is better).  Here's an example of how this can go
3031         bad.  A browser that always computes a task in some horribly long time (say, 1000ms) but never
3032         varies that time will perform better than a browser that usually computes the task super quickly
3033         (say, 10ms) and sometimes just a little bit less quickly (say, 15ms).  The former browser will
3034         have an RMS of 0 and an average of 1000.  The latter will have a RMS somewhere around 3.5 and an
3035         average of 12.5 (assuming equal probability of 10ms and 15ms).  The geomean of (0, 1000) is 0.
3036         The geomean of (3.5, 12.5) is 6.6.  Lower is better, so the former browser scores higher - even
3037         though it's obviously never better to have a browser always complete a task in 1000ms when a
3038         different browser can do it in 15ms in the worst case.
3039
3040         JetStream should not have this pathology.  The right way of avoiding it is to replace RMS with
3041         some other metric of how bad things get.  A good metric is the average of the worst percentile.
3042         The worst 1% or the worst 5% would be good things to average.  This will catch cases where the VM
3043         jittered due to JIT or GC, but it never have the pathology that we end up giving the better score
3044         to a VM whose best case is worst than another VM's worst case.
3045
3046         For now, this change uses the highest samples above the 95% percentile. I'm not yet sure if that
3047         is the best thing - it might include too many scores that are around the best-case performance -
3048         but it's certainly better than RMS and it might be good enough to keep. But because of that
3049         uncertainty, I'm setting the version to be "1.1-alpha1" to indicate that we aren't ready to
3050         release this yet.
