[petsc-dev] Configure hangs on Summit

[Zhang, Junchao]

Richard,

Hi Junchao,

Glad you've found a workaround, but I don't know why you are hitting this problem. The last time I built PETSc on Summit (just a couple days ago), I didn't have this problem. I'm working from the example template that's in the PETSc repo at config/examples/arch-olcf-summit-opt.py.

Can you point me to your configure script on Summit so I can try to reproduce your problem?

  TESTING: configureMPIEXEC from config.packages.MPI(config/BuildSystem/config/packages/MPI.py:170)

On the machine one has to use script to submit jobs. So why do we need configureMPIEXEC? Do I need to use --with-batch? I remember we removed that.
