<div class="gmail_default">Recently, I've been playing around with petsc4py to solve a battery simulation, which takes too long to solve using scipy solvers. 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.</div>

<div class="gmail_default">For the record, I'm using PETSc's cg solver.</div>
