[petsc-dev] valgrind errors in the SUPERLU*

Sherry,

  We think there is a small memory leak in Superlu; could you check it?

Another problem is that when running PETSc examples with Superlu we see valgrind warning messages about copying uninitialized data in MPI calls in superlu. This is cause by hypre allocating some buffer space, but only putting values in part of the buffer and then sending the entire buffer via MPI to some other process. Technically this is not an "error" if you never access the non initialized data on the receiver process but it makes valgrind unusable for finding TRUE memory issues (since the output is filled with false positives). 

   The issue could be fixed by either 1) initializing the complete buffer allocated (for example when it is malloced), then MPI won't see uninitialized data or better IMHO 2) send shorter messages that don't contain this part of the buffer that is never used anyway.

Thanks 

  Barry
