Please remove the pipe to process stdout as this will mess up the compare/run output which should be csv |
okay note that it will not print console.logs/error of child scripts in the terminal then while with fork pipes are established automatically |
|
That was the old behavior, no? |
when not using CPUSET command benchmark will use fork to run the child scripts and fork prints out console.log/console.errors..info..warn of forked instance to the parent instance thus you can see the logs in the terminal. I wanted to maintain that behavior of fork while using spawn, so that's why we ned to pipe stdio and stderr to the parent (Fork does this by default) |
I know it's unrelated to this PR, but wouldn't |

Fix (ipc) in the stdio configuration of the spawn function within the benchmark subsystem.
This PRs fixes the mistake in PR (benchmark: conditionally use spawn with taskset for CPU pinning) where I removed IPC by mistake due to which child.on("message") listener wasn't working.
I also made sure of cpu usage of cores provided to taskset and checked if the csv is all good
Fixes: #52233
