can't find openmpi binaries (SL 6.2)

[Ocifer]

Hi,

I'm running SL 6.2. I've installed the openmpi.i686 packages and the development packages. How do I get the openmpi wrappers to compile and run. They state on their site that one should use the wrappers (such as mpicc for compilation or mprun to run)? How do I get these on SL 6.2? I've looked in (I think) all my /bin directories and I don't see the relevant binaries.

My terminal shell complains that it can't find the mpicc command.

Look under /usr/lib64/openmpi/bin/ (or /usr/lib/openmpi/bin/ on 32 bit).

Thanks, that was the right location. So for anyone having similar questions:

To use openmpi (I am running 32 bit on this particular computer), install the following:

CODE

yum install openmpi.i686 openmpi-devel.i686

Then, you need to add:

/usr/lib/openmpi/bin to the PATH variable

/usr/lib/openmpi/lib to the LD_LIBRARY_PATH variable

Both of these can be achieved by adding lines to .bash_profile file in your home folder (google changing PATH or LD_LIBRARY_PATH).

Once the .bash_profile file has been modified, log out and log back in for it to take effect.

Hope that helps people in the future.

EDIT: I had been looking all through usr/lib and usr/bin and similar with no luck. The shared libraries and exectubles for openmpi are all found in /usr/lib/openmpi directory. ( or /usr/lib64/openmpi for 64 bit ) From there you need to navigate to either the /lib or /bin subdirectory if you want to see what's there.
