<font face="serif">From zeus and all of the systems in Lab 204
(except for those that are down) I have removed ALL versions of
the MPI runtime environment and any development files. Due to
system updates there were multiple versions of MPI out there in
addition to the "official release" from the OpenMPI team.<br>
<br>
I then reinstalled a version of MPI that is appropriate for the
version of CentOS that is on Zeus and the systems in lab 204. To
avoid confusion, during the install process I made sure that there
were no references to the CUDA libraries (so you should no longer
see those warnings). It took about four and a half hours, but we
should have a working system.<br>
<br>
Here is what I need you to try immediately:<br>
<br>
1. In you .bash_profile make sure that /usr/lib64/openmpi/bin is
in your executable PATH<br>
<br>
2. Also in your .bash_profile make sure that your LD_LIBRARY_PATH
include /usr/lib64/openmpi/lib<br>
<br>
3. log out of zeus and log back in to make sure that all your
paths are set correctly<br>
<br>
4. on zeus REMAKE your MPI files so that the libraries are all
synced properly with the execution environment<br>
<br>
5. on zeus try to run a single node mpi executable<br>
<br>
mpirun -n 2 -host zeus mpimmm<br>
<br>
6. Try to run the PBS/TORQUE script in the job manager that was
failing the other day and see if it now works<br>
<br>
<br>
Please keep me posted and let me know if it is or is not working.<br>
<br>
Systems 4, 8, and 21 are down. System 4 is hopeless, I will try
to fix 8 and 21 later. It would be great if you could knock out
a bunch of your timings today for the C version of MPIMMM.<br>
