Parallel python + ??

[Thor]

Hi,

I am running a program using Parallel Python and I wonder if there is a
way/module to know in which CPU/core the process is running in. Is that
possible?

This is of course OS-specific. On Linux, you can parse the proc filesystem:

>>> open("/proc/%i/stat" % os.getpid()).read().split()[39]

You can use the "taskset" utility to query or set CPU affinity on Linux.

It is going to be in Linux (mainly) I was thinking about something like
this:

import Module

def process(self):
print "I am running on processor", Module.cpu,"core", Module.core
....
.....

Checking the raskset right now... Thanks.
