Looking at pdgstrf2_trsm() it appears that you are sending square matrices of dimension MPI_Isend (ublk_ptr, nsupc * nsupc, MPI_DOUBLE, pr) of dimension nsupc * nsupc but then using the received matrix as a 'u' (upper diagonal matrix)? This means that some of the entries in the matrix are never used and hence never set (the below diagonal ones)?<br>
<br>
In order to prevent MPI ever seeing those uninitialized values it seems you should use calloc at pdgstrf (pdgstrf.c:737) ?<br>
<br>
Thanks for looking at this.<br>

Then, at each step, only part of the buffer is used for send (with correct data initialized). The size argument in MPI_Isend() tells how much data should be sent at this step. That is, I never send uninitialized memory. I am surprised valgrind complains this.<br>

> > 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).<br>
