I encountered a strange problem on my dual proc. XEON RH Linux 7.1 machine. When I link my program with -lmkl or -lmkl_p4 libraries I have random problems in eigenvalue solver (sometimes it finds 0 eigenvalues, but returns INFO=0 as well). On PIII machine this code works well. Finally, I tried to link -lmkl_p3 on my XEON machine and it works!! But the speed of blas routines is almost 50% down.... Do you have any comments on this problem?
