P.
I am currently encountering the same error, and am engaged in a discussing with their support to find the cause.
(The "module swap" should go into the *.run script instead since the *.ini file should remain independent of the MPI stack used. However, I encountered the same problem as you, and will commit by state once things are working for me.)

Hello!
I am trying to run the Tutorial for New Users (https://docs.einsteintoolkit.org/et-docs/Tutorial_for_New_Users) on Lonestar (this is the first time I am using the machine). My job fails with the following error (in the .out) file:
....
Simulation name: static_tov_8 Running simulation static_tov_8 Preparing: Checking: /scratch/01489/pajith/simulations/static_tov_8/output-0000-active c324-310.ls4.tacc.utexas.edu Fri Apr 13 01:46:47 CDT 2012 Environment: Starting: TACC: Starting up job 541416 TACC: Setting up parallel environment for OpenMPI mpirun. TACC: Setup complete. Running job script. TACC: starting parallel tasks... TACC: Could not determine MPI stack. Exiting! ...
These are the modules that are loaded:
login2$ module list Currently Loaded Modules: 1) TACC-paths 2) Linux 3) cluster-paths 4) intel/11.1 5) gzip/1.3.12 6) tar/1.22 7) cluster 8) TACC 9) openmpi/1.4.3
And my defs.local.ini file looks like this:
# Defaults for all machines [default] user = pajith email = ajith_p@ligo.caltech.edu allocation = TG-MCA02N014 thornlist = manifest/einsteintoolkit.th
[lonestar] user = pajith email = ajith_p@ligo.caltech.edu allocation = TG-MCA02N014 sourcebasedir = /work/01489/@USER@ basedir = /scratch/01489/@USER@/simulations envsetup = module purge && source /etc/profile.d/tacc_modules.sh && module load TACC && module swap mvapich2 openmpi
The extra bits were added to the envsetup (following the advice of Roland Haas) because by default the system was loading the mvapich2 module and *earlier* my jobs were failing with the following error:
Error: You can only have one MPI module loaded at time. You already have mvapich2 loaded. To correct the situation, please enter the following command:
module swap mvapich2 openmpi/1.4.3
Please let me know if you need any additional information.
Thanks a lot! Ajith
PS: Sorry for spamming you all. I am not sure if this mailing list is the appropriate place to bring this issue. I tried to submit a bug report at https://trac.einsteintoolkit.org/. But my ticket was rejected as Trac suspected it as spam!
