Identify core an Erlang process

Question

Any way to identify the specific core an Erlang process is scheduled on?

Let's say you spawn a bunch of processes to simply print out the core the process is running on, and then exit. Any way to do this?

I spent some time reading docs and googling but couldn't find anything.

Thanks.

EDIT: "core" = CPU core number (or if not number, another identifier that identifies the CPU core).

Answer 1

There is erlang:system_info(scheduler_id) that in most cases is maped to a logical core. But this information is pretty ephemeral because the process may be suspended and resumed on any other scheduler.

What is your use case that you really need that kind of information?
