[petsc-users] Are performance benchmarks available?

[Barry Smith]

   While I agree that having this type of information available would be very useful it is surprisingly difficult to do this and keep it up to date, plus we have little time to do it, so unfortunately we don't having thing like this. 

   We should do this! Perhaps pick one or two problems and run them with say a simple preconditioner like ASM and then GAMG on a large problem with a couple of different number of processes, say 1, 32 and 256 then run them once a month to confirm they remain the same performance wise and make the performance numbers available on the web. Maybe using Mark's ex56.c case.

   I'll try to set something up

Always a big pain to try to automate the running on those damn batch systems!
