Hi SimVascular team!
I am using Ubuntu 16.04 and SV(SimVascular-2017-04-09),
In Simulations step, I choose "Number of Processes: 8", and click Run Simulation.
It looks good, no error or warning, all 8 CPU are 100% in use, but when I check in directory, there is no 8-procs_case/ under the project folder
then I tried "mpiexec -np 8 svsolver" in command, again, no 8-procs_case/
I checked http://simvascular.github.io/docsFlowSo ... runningjob, still not fixed this problem,
Any help would be appreciated!

Re: no 8-procs_case
Hi,
you probably have the same problem as I had: viewtopicPhpbb.php?f=188&t=7948&p=0&start=0&view=
It also didn't work properly for me using a manually installed OpenMPI, but I got it working using the mpiexec bundled with the svsolver.
Cheers,
Rok

Re: no 8-procs_case
Hi Abel,
Please update SimVascular to the latest version: you need to install two packages: both SimVascular and svSolver from simtk.
If you still have the issue, there a few methods you can try to solve it:
Method 1:
run "mpiexec -version" in terminal to check if the default mpi is mpich or openmpi. If it's mpich, it should mention "HYDRA" in the version info.
if not, you need to change the default one back to mpich. svSolver can't run with openmpi.
Method 2:
If you'd like to run from the terminal, you can try the command like
/usr/local/sv/svsolver/[yyyy-mm-dd]/bin/mpiexec -np [numver of processor] /usr/local/sv/svsolver/[yyyy-mm-dd]/svsolver
If it works, and you want to run from the GUI, you can refer to
http://simvascular.github.io/docsFlowSo ... figuration
specify MPIExec as /usr/local/sv/svsolver/[yyyy-mm-dd]/bin/mpiexec
Thanks,
