OpenMP with Intel E5649 Processor

Postby kamalm » Sat Apr 26, 2014 9:49 am

I am using OpenMP under Linux OS with one node consisting of 12 cores (two sockets, each has 6-core Intel E5649 Processor). My results came completely different than that on my Laptop (32-bit Core i7) and with high error. What portability and platform issues I may consider in transferring my code to Linux (64-bit)? The program is Conjugate Gradient in C language (gcc 4.9 compiler).

Hi,

Did you try to run and compare results without OpenMP at all? (Recompiling/relinking, of course).

HTH,

Fernando.
