Hi all,
I am trying to use the parallelization capability(with MPI) from Trilinos. I
am solving the system of linear equations with Belos::Block Gmres.
I don't see the improvement in efficiency as I increase the number of
processors. Follwing are the timings I observed,
1)with one processor:
Resources:
cput=02:19:47,mem=5220848kb,vmem=5508396kb,walltime=02:19:53
2)wth 2 processors
Resources:
cput=04:44:55,mem=5267036kb,vmem=5718936kb,walltime=02:22:34
3)with 3 processors
Resources:
cput=09:35:22,mem=7185156kb,vmem=7990468kb,walltime=02:23:58.
It will be great if somebody can explain how to interpret these results.
Thanks in advance,
Ramakrishna
