[mpich-discuss] MPICH associating process with a core

[chong tan]

I was looking for this a while back, and found none.  I created a work around for
myself:

each process dumps its rank and process id at the begining of the run (into somewhere),
and I map those id to the output of 'top' (that show the CPU binding).  you can google info on 
enabling CPU info with top.

Subject: [mpich-discuss] MPICH associating process with a core

Hi,

Is there a way in the MPI library to report which process is running
on which core in a SMP system with
shared memory MPI programming model?

I dug out the library calls and only found out
MPI_Get_processor_name to be close. But it reports the machine itself
not the core the process is running
on.

thanks,
john
