Performance runner for d8.
|
|
|
|
Call e.g. with tools/run-perf.py --arch ia32 some_suite.json
|
|
|
|
The suite json format is expected to be:
|
|
{
|
|
"path": <relative path chunks to perf resources and main file>,
|
|
"name": <optional suite name, file name is default>,
|
|
"archs": [<architecture name for which this suite is run>, ...],
|
|
"binary": <name of binary to run, default "d8">,
|
|
"flags": [<flag to d8>, ...],
|
|
"test_flags": [<flag to the test file>, ...],
|
|
"run_count": <how often will this suite run (optional)>,
|
|
"run_count_XXX": <how often will this suite run for arch XXX (optional)>,
|
|
"resources": [<js file to be loaded before main>, ...]
|
|
"main": <main js perf runner file>,
|
|
"results_regexp": <optional regexp>,
|
|
"results_processor": <optional python results processor script>,
|
|
"units": <the unit specification for the performance dashboard>,
|
|
"tests": [
|
|
{
|
|
"name": <name of the trace>,
|
|
"results_regexp": <optional more specific regexp>,
|
|
"results_processor": <optional python results processor script>,
|
|
"units": <the unit specification for the performance dashboard>,
|
|
}, ...
|
|
]
|
|
}
|
|
|
|
The tests field can also nest other suites in arbitrary depth. A suite
|
|
with a "main" file is a leaf suite that can contain one more level of
|
|
tests.
|
|
|
|
A suite's results_regexp is expected to have one string place holder
|
|
"%s" for the trace name. A trace's results_regexp overwrites suite
|
|
defaults.
|
|
|
|
A suite's results_processor may point to an optional python script. If
|
|
specified, it is called after running the tests like this (with a path
|
|
relatve to the suite level's path):
|
|
<results_processor file> <same flags as for d8> <suite level name> <output>
|
|
|
|
The <output> is a temporary file containing d8 output. The results_regexp will
|
|
be applied to the output of this script.
|
|
|
|
A suite without "tests" is considered a performance test itself.
|
|
|
|
Full example (suite with one runner):
|
|
{
|
|
"path": ["."],
|
|
"flags": ["--expose-gc"],
|
|
"test_flags": ["5"],
|
|
"archs": ["ia32", "x64"],
|
|
"run_count": 5,
|
|
"run_count_ia32": 3,
|
|
"main": "run.js",
|
|
"results_regexp": "^%s: (.+)$",
|
|
"units": "score",
|
|
"tests": [
|
|
{"name": "Richards"},
|
|
{"name": "DeltaBlue"},
|
|
{"name": "NavierStokes",
|
|
"results_regexp": "^NavierStokes: (.+)$"}
|
|
]
|
|
}
|
|
|
|
Full example (suite with several runners):
|
|
{
|
|
"path": ["."],
|
|
"flags": ["--expose-gc"],
|
|
"archs": ["ia32", "x64"],
|
|
"run_count": 5,
|
|
"units": "score",
|
|
"tests": [
|
|
{"name": "Richards",
|
|
"path": ["richards"],
|
|
"main": "run.js",
|
|
"run_count": 3,
|
|
"results_regexp": "^Richards: (.+)$"},
|
|
{"name": "NavierStokes",
|
|
"path": ["navier_stokes"],
|
|
"main": "run.js",
|
|
"results_regexp": "^NavierStokes: (.+)$"}
|
|
]
|
|
}
|
|
|
|
Path pieces are concatenated. D8 is always run with the suite's path as cwd.
|
|
|
|
The test flags are passed to the js test file after '--'.
