I almost copied arch-olcf-summit-opt.py. The hanging is random. I met it few weeks ago. I retried and it passed. It happened today when I did a fresh configure.

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

<div>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.</div>
