asv_bench_memray

This a proof-of-concept externally defined memray benchmark plugin for asv.

Usage

In your asv.conf.json add the following to the requirements matrix:

"matrix": {
    "req": {
        "numpy": ["1.21"],
        "asv_plugin_memray": [""]
    },
},

This should be enough for an example like the following to run:

import numpy as np

class MyBenchmark:
    params = [10, int(2e4)]

    def ray_sum(self, n):
        self.data = np.random.rand(n)
        np.sum(self.data)

Which should result in something roughly like:

ASV_RUNNER_PATH="../asv_runner" asv run --bench sum

Development

During development, one needs to pass a relative path:

"matrix": {
    "req": {
        "asv_bench_memray": ["../asv_bench_memray"]
    },
},

Also it may be necessary to cleanup older environments and explicitly point to an instance of asv_runner:

rm -rf .asv && ASV_RUNNER_PATH="../asv_runner" asv run --bench sum

Personally I keep benchmarks for testing at an experiments repo, but any local test will do.

Conventions

Like all externally defined benchmark plugins for asv, this has a strict hierarchy.

The package name begins with asv_bench
Benchmarks are defined in a benchmarks folder under the package module
Each exported new benchmark type has the export_as_benchmark = [NAMEBenchmark] attribute

For more conventions follow the documention of asv_runner.
