I thought about this again. The main trouble is that users may not want to
share the information,
and currently there is a culture of secrecy around large runs. I think you
have to offer something
in return. I propose we offer a service like Google Analytics (or
www.statcounter.com). That is,
people autosend performance results and we deliver canned analyses for free,
and better ones
for consulting fees (so that no one will actually do it). Then, after a
little while, we make it opt-in
in configure, and poof we have an idea about a fair fraction of PETSc runs.
