Pardiso seg faults on SGI UV 1000

[Rawlins__David]

Hi,

The Pardiso test problem pardiso_sym_c.c runs fine on my Intel Linux 64 bit machine, but is seg faulting on the factorization call (phase=11) when I try to compile and run it on an SGI UV 1000. I am using the MKL version 10.2.3.029. Are there any issues running the MKL on an SGI UV?

Thanks,

Dave

Hi Dave,

Yes, please see the lntel MKL 10.2 Fixes List here.

Could you update the MKL version till Update 7 and check if the problem is still there?

Gennady,

Thanks for pointing me to the Fixes List. This item led me to a solution:

DPD200157417 Intel MKL crash on 256 or greater core count systems for Windows and Linux

The SGI UV has 256 processors. I found that if I run my code with the "dplace" command, it runs fine.

I also found that I could run the Pardiso test problem with version 10.3 without using dplace, but I'm having other issues with 10.3 and my code that I will address in another post.

Thanks,

Dave
