Hi Sherry,<br>
<br>
I finally figured out a minimalistic setup (attached) that
reproduces the problem.<br>
<br>
I use petsc-maint:<br>
<br>
git clone -b maint <a class="moz-txt-link-freetext" href="https://bitbucket.org/petsc/petsc.git">https://bitbucket.org/petsc/petsc.git</a><br>
<br>
and configure it in the debug mode without optimization using the
options:<br>
<br>
--download-superlu_dist=1 \<br>
--download-superlu_dist-commit=origin/maint \<br>
<br>
Compile the test, assuming PETSC_DIR points to the described petsc
installation:<br>
<br>
make ex16<br>
<br>
Run with:<br>
<br>
mpirun -n 2 ./ex16 -f binaryoutput -pc_type lu
-pc_factor_mat_solver_package superlu_dist<br>
<br>
Matrix partitioning between the processors will be completely the
same as in our code (hard-coded).<br>
<br>
I factorize the same matrix twice with the same PC object.
Remarkably it runs fine for the first time, but fails for the
second.<br>
<br>
Thank you very much for looking into this problem.<br>
<br>
Cheers,<br>
Anton<br>
