PLASMA-2.4.6 : Error in Plasma_Init

Postby tiger991 » Tue Sep 25, 2012 10:07 am

Hello,

I'm currently trying to integrate PLASMA in my coe but I have a problem. My code is a MPI code compiled with Intel 12.1.0 ifort and OpenMP 1.5. I installed PLASMA with the sequential version of Intel MKL library. The examples from PLASMA run fine. But, inside my program, a call to PLASMA_Init gives me this error:

forrtl: severe (71): integer divide by zero

A little debug shows me the problem comes from Plasma_Init_affinity. Then, on the cluster where I launch my program, SLURM is the job dispatcher: SLURM decide the affinity policy of the processes and the threads. I got the feeling that Plasma need to access all the cores available. May be a conflict ?

When I disabled SLURM affinity, it seems to work for little case...
