Please give more details about your problem:
* Are you solving the same sized problem each time, or increasing it? The CPU time is going up, but wall time is stable.
* How are you partitioning your problem?
* How are you executing your parallel job and on what type of system?

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:
2)wth 2 processors
3)with 3 processors
It will be great if somebody can explain how to interpret these results.
Thanks in advance,
