Hello, I would thank anyone who can help me with this problem. I made a Bewoulf cluster using Ubuntu with two computers and I'm trying to use Scalapack but the CPU use is really low (25% most of the time) so its taking more time than just using Lapack. I'm trying to link with the ATLAS library but it still does not solve the problem. The way I am compiling is:
mpif90 -lscalapack-openmpi -lblacsF77init-openmpi -lblacsCinit-openmpi -lblas-openmpi -llapack_atlas -lf77-blas -lcblas -latlas -lpthread
Thank you very much
