thornyflat - production run segmentation fault

Create issue
Issue #2598 new
Maria created an issue

Simfactory scripts for ThornyFlat give segmentation fault in production run. I am attaching the cfg, ini, run and sub scripts.

In the simulations directory, the SIMFACTORY directory does not have inside the subdirectories: exe, cfg, run and par and NODES is empty. The only file is the properties.ini, which includes:

    With the command:

    ./simfactory/bin/sim create-submit tov --configuration etk --machine=thornyflat --parfile=par/static_tov.par --cores=10

    I am getting the warnings:

    Warning: Current Working directory does not match Cactus sourcetree, changing to /users/mbh0012/Cactus

    Warning: Too many threads per process specified: specified num-threads=20 (ppn-used is 40)
    Warning: Total number of threads and number of threads per process are inconsistent: procs=10, num-threads=20 (procs*num-smt must be an integer multiple of num-threads)
    Warning: Total number of threads and number of cores per node are inconsistent: procs=10, ppn-used=40 (procs must be an integer multiple of ppn-used)

    Again, the simulation gave me Segmentation Fault. In essence, the problem seems to be here:

    /scratch/mbh0012/simulations/tov/output-0000/SIMFACTORY/RunScript: line 24: 9372 Segmentation fault (core dumped) mpiexec -n 1 -npernode 2 /scratch/mbh0012/simulations/tov/SIMFACTORY/exe/cactus_etk -L 3 /scratch/mbh0012/simulations/tov/output-0000/static_tov.par

    This can be traced to, which is attached above. Most likely, there is an error in this line:

    mpiexec -n @NUM_PROCS@ -npernode @(@PPN_USED@ / @NUM_THREADS@)@ @EXECUTABLE@ -L 3 @PARFILE@

    The helpdesk thinks that is an internal problem with Einstein Toolkit, bug or a bad software design, which has as result not checking for proper allocations. I suspect the problem is in the submit or run files.
