[petsc-users] error when trying to compile with HPDDM

[Jose E. Roman]

This happens because you have typed 'make -j128'. If you just do 'make', PETSc will choose a reasonable value (-j59 in your case).

Satish: do we want to support this use case? Then a possible fix is:

diff --git a/config/BuildSystem/config/packages/slepc.py b/config/BuildSystem/config/packages/slepc.py
