Topic: High precision timer

Is there a platform that exposes the high precision timer?

Richard Feldman (Oct 19 2022 at 18:42):

not currently, but we could add it to the CLI platform!

Arbil (Oct 19 2022 at 18:43):

That would be useful for benchmarking

Brendan Hansknecht (Oct 19 2022 at 18:59):

What type of benchmarking are you trying to do? We have a benchmark platform that is pretty simple that specifically is for testing algoritms and their executions speed. If you are looking at more holistic performance, I would definitely advise looking at an external timing tool like hyperfine.

Arbil (Oct 20 2022 at 04:23):

Microbenchmarks and algorithms. Is the benchmark platform cli/benches/time_bench.rs?

Brendan Hansknecht (Oct 20 2022 at 04:24):

crates/cli_testing_examples/benchmarks

Brendan Hansknecht (Oct 20 2022 at 04:25):

Just a number of simple apps that bench specific algorithms. The platform is a simple zig timer (could probably be improved).

Brendan Hansknecht (Oct 20 2022 at 04:26):

Also has the ability to load integers for std for config....so super minimal.

Brendan Hansknecht (Oct 20 2022 at 04:26):

Oh, and can write to stdout

Brendan Hansknecht (Oct 20 2022 at 04:27):

If that is too minimal for what you want to do, I think adding timers (or just a way to get the current time in some high precision format) to the cli platform would be very reasonable.

Brendan Hansknecht (Oct 20 2022 at 04:28):

Let us know if you need help with the platform

Arbil (Oct 20 2022 at 04:58):

Thank you, will play with this
