[petsc-dev] Seeking OLCF users complaining about poor build times

[Barry Smith]

  Shockingly this is not bad (though more than it should be), we've seen times like an hour on the NERSC and ANL systems. 

  If you have time :-) could you run with metis, permetis, superlu_dist and hypre --with-debugging=0 and get the times separately for configure and make? 

  Thanks
