Hi Team,
We are developing an application which can handle only POSIX threads and
POSIX synchronization APIs. I would like to know if the OpenMPI runtime
implementation makes use of the POSIX threads and POSIX synchronization
APIs (lock, mutex, semaphore, signal, etc.) or not, in particular, th
e. You might try adding —bind-to none to your cmd line.

Hi Team,
I am trying to test an application with libnuma on openmpi 1.8.1. The code
compiles, but at runtime am getting libnuma warning and it dies with
segmentation fault.
libnuma: Warning: cpu argument 8 is out of range

Hi Ralph,
I am able to run the program.. Thanks a lot for your help.

Hi Team,
I am trying to setup openmpi 1.8.1 on a system with infiniband.
Am using the default configure options. I am not using any multithreading
option.
After installation, no openib components are available.
I tried even with flag: '--with-verbs', still no use.
Should i use any other flag
