[CIG-SEISMO] SPECFEM3D: Segmentation fault - xgenerate_databases

[gmatharu at eos.ubc.ca]

Hi

 I have been running SPECFEM3D on a couple of different clusters on the
Westgrid computer consortium. As I'm not sure what details are relevant
I've included links which explain the builds of either cluster.

http://www.westgrid.ca/support/quickstart/lattice
http://www.westgrid.ca/support/quickstart/orcinus

I'm currently generating a mesh on 256 processors which is 256*128*60
(X/Y/Z). A few months back on an older build of the software I had no
issues generating a mesh on the orcinus cluster and running the solver.
However with an updated package I am encountering segmentation fault
errors when running xgenerate_databases on both Lattice and Orcinus (using
ifort,icc and mpif90 on both). My submission scripts seem correct and the
initial meshing seems to work ok, however I'm at a loss as to what's
causing this error. Do you have any recommendations on how to resolve this
issue? If you require further information let me know.

Best Regards,

Gian

Below is a snippet of the error message I receive.
