[petsc-users] pedagogical example

[Gideon Simpson]

I was hoping to demonstrate in my class the computational gain with petsc/mpi in solving a simple problem, like discretized poisson or heat, as the number of processes increases.  Can anyone recommend any of the petsc examples for this purpose?  Perhaps I’m just using poorly chosen KSP/PC pairs, but I haven’t been able to observe gain.  I’m planning to demo this on a commodity intel cluster with infiniband.
