I'm running su2 on Windows7 and I have no problems at all with the single threaded runs but when I try to run parallel I get this problem.
I assume the problem is with my conf file so you can have a look at it here https://dl.dropboxusercontent.com/u/...v_NACA0012.cfg
If I run it without -divide I get the same error but instead of su2_cfd the problem is with su2_prt. I am fairly convinced that my mpirun and openmpi are configured correctly.

PS C:\SU2\test> parallel_computation.py -f .\inv_NACA0012.cfg -n 8 -divide
8 total processes failed to start
SU2 process was terminated by signal '125'
--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not access
or execute an executable:

Executable: C:\SU2\SU2_CFD
Node: BELISKNER

while attempting to start process rank 0.

Thanks Very much!

Hello!

The error could be because of ".\" prefixed to inv_NACA0012.cfg, this would mean its an executable. While I work on a different platform I could produce an error by using .\inv_NACA0012.cfg.


Try this: parallel_computation.py -f inv_NACA0012.cfg -n 8 -divide

Let me know if it works!

Same error

i think you need Windows Server OS, or maybe at least Windows 7 Ultimate.

when I tried going through the installation guidlines for multiprocessor setup, I ran into a message indicating I need Windows Server installed.
(It's been a while, so I don't remember exactly what the message was, but I remember that it became clear I couldn't use mulitple cores unless I spent money upgrading my OS.)

I've since decided to buy a new system (through my new company) and am trying to figure out if Windows 7 Ultimate 64-bit OS will suffice.
