[petsc-users] petsc without MPI

[Povolotskyi, Mykhailo]

Let me explain the problem.

This log file has

#ifndef PETSC_HAVE_MPI
#define PETSC_HAVE_MPI 1
#endif

while I need to have PETSC without MPI.

The log you sent has configure completely successfully. Please retry and send the log for a failed run.

  Thanks,
