Do you know what the call sequence should be on CETUS to get
valgrind attached to PETSc?<br>
Would this work for example:<br>

Hmm, this should never happen. In the code
ierr = PetscTableCreate(aij->B->rmap->n,mat->cmap->N+1,&gid1_lid1);CHKERRQ(ierr);
for (i=0; i<aij->B->rmap->n; i++) {
for (j=0; j<B->ilen[i]; j++) {
PetscInt data,gid1 = aj[B->i[i] + j] + 1;
ierr = PetscTableFind(gid1_lid1,gid1,&data);CHKERRQ(ierr);
Now mat->cmap->N+1 is the total number of columns in the matrix and gid1 are column entries which must always be smaller. Most likely there has been memory corruption somewhere before this point. Can you run with valgrind? <a class="moz-txt-link-freetext" href="http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind">http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind</a>

Hi,
I am running a code on CETUS and I use PETSc for as a linear solver.
Here is my submission command:
qsub -A shearbands -t 60 -n 4 -O 4nodes_32cores_Mult --mode script 4nodes_32cores_LU
Here is "4nodes_32cores_LU":
#!/bin/sh
LOCARGS="--block $COBALT_PARTNAME ${COBALT_CORNER:+--corner} $COBALT_CORNER ${COBALT_SHAPE:+--shape} $COBALT_SHAPE"
echo "Cobalt location args: $LOCARGS" >&2

Well at least that is what I think comes out after I read all the jammed up messages from my MPI processes...
I would guess that I am trying to allocate more memory than I should which seems strange since the same problem runs fine on 2 nodes with 16 cores/node
Thanks for the help
Best,
Luc
