[petsc-users] valgrind with petscmpiexec

[Fande Kong]

Hi All,

I tried to use valgrind to check if the simulation is valgrind clean
because I saw some random communication fails during the simulation.

I tried this command-line

petscmpiexec -valgrind -n 576  ../../../moose-app-oprof  -i input.i
-log_view -snes_view


But I got the following error messages:

valgrind: Unable to start up properly.  Giving up.

I did a bit search online, and found something related
https://stackoverflow.com/questions/13707211/what-causes-mkstemp-to-fail-when-running-many-simultaneous-valgrind-processes

But do not know what is the right way to fix the issue.

Thanks so much,

Fande,
