dop_timer

This binary exists to time the behavior of distributed (local, global) collective operations.

This binary uses the gRPC OTEL exporter to send traces to an OTEL Collector on port 4317.

Example

Setup an OTEL Collector

There are many ways to do this; one of the simplest is to use the jaegertracing/all-in-one:latest docker image:

bash

$ docker run -e OTEL_TRACES_SAMPLER=always_off -e COLLECTOR_OTLP_ENABLED=true -p 16686:16686 -p 4317-4318:4317-4318 -p 14250:14250 -p 14268:14268 -p 14269:14269 jaegertracing/all-in-one:latest

Then navigate to localhost:16686 to view traces.

Run the binary, with the OTEL Collector endpoint as an argument:

bash

$ cargo run -p dop_timer --features cuda -- --tracing otel
