[petsc-users] PETSc scaling for solving system of equations

I also have access to an HPC cluster with a few nodes, each with a dozen CPU cores. However, I can't seem to get any further speedup past 4 processors. Very likely, I'm doing something wrong. I'd really appreciate it if someone could shed some light on this.
