Is there a set of HPC benchmarks that the core PETSc developers recommend
for evaluating architectures? Meaning to evaluating claims about
performance to support rational acquisition decisions on new systems. I
recall speaking briefly with Jed at a conference about a benchmark that
was more representative of PDE calculations, maybe representing a
Krylov iteration arising from an unstructured mesh or something like
that. I'm talking about long term acquisition of real workhorse petascale
systems not the cutting edge.
