Mentat segmentation fault on DECS

The increase of the stack size (ulimit -s) that is triggered in DAMASK_env can lead to a segmentation fault when calling mentat.

To circumvent this issue, progressively reduce the stack size with

ulimit -s xxx

until the connection to XQuartz works out.

PETSc 3.7.4 on DECS cluster

The CMM environment has been updated to use openMPI 2.0.1 and PETSc 3.7.4. In order for DAMASK to properly work under those conditions, apply an intermediate patch as long as the official DAMASK release has not yet adopted PETSc 3.7.x as default.
