Hi I wonder if there's any way I can speed up KSPSetUp()? On larger test cases with 1e8 unknowns, it's taking more than 17 hours (and still incomplete) to execute this command across 3 processors with BoomerAMG, where as the whole setup+solving takes 2 min if the problem size is 1e6.
I've verified that the matrices has completed assembly and I'm using the non-debugging Petsc version. Jerome -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-users/attachments/20090130/069eab5a/attachment.htm>
