In MatStashBlockTypeSetUp()
PetscCallMPI(MPI_Type_create_resized(stype, 0, stash->blocktype_size,
&stash->blocktype));
In MatStashScatterDestroy_BTS(MatStash *stash)
if (stash->blocktype != MPI_DATATYPE_NULL)
PetscCallMPI(MPI_Type_free(&stash->blocktype));
So
Dear Petsc community,
Recently, I encountered a memory leak while using Valgrind (3.25.1) with
MPI (2 processes, MPICH 4.21.1) to test a PETSc-based code, which is a
variant of the pestc's built-in example.
