Hi,
running parallel code on my workstation (with OpenIndiana) I discovered
that MPI processes were migrated on a regular basis from one core to
another.
On SunOS systems the command 'pbind' allows binding a process to a specific
core.
So I am wondering if binding automatically each process to the next
available core is supported directly from MPICH ?
Best regards
Aurelien

Hi Vaibhav,
The error is caused by missing nonblocking collective functions in
mpich2-1.4.1. You are using an very old version of MPICH (2011) with a
recent Intel MPI benchmark (2013).
As far as I know, MPICH started to support nonblocking collectives since
mpich-3.0. Right now our latest stable release is mpich-3.1.4. You can
download it from here. https://www.mpich.org/downloads/
Best regards,

Hello there, I'm trying to do the performance analysis of my MPI cluster using Intel MPI Benchmarks. I am using mpich2-1.4.1 source code and Intel MPI Benchmarks 4.0 Version 2.
But I'm encountering some errors. I setup the environmental variables in make_mpich file in the src directory.
I extracted the archive and ran:
make -f make_mpich
Part of the output where we see errors is attached below:

collect2: ld returned 1 exit status
make[1]: *** [NBC] Error 1
make[1]: Leaving directory `/work/imb/src'
make: *** [IMB-NBC] Error 2
Is there some step which I might have overlooked?
I need to check the performance for mpich2-1.4.1 only.
Please help.
