Running on the cluster: machine file -> Filename too long???
 
Good day

I'm trying to run Star-CCM+ on the 4-node cluster (NodeA, NodeB, NodeC, NodeD).
Network connection is ok, running on any one/two/three node(s) is ok too.

Machine File contents:
Code:

NodeA:28
NodeB:28
NodeC:28
NodeD:28

Settings:

Error message:

Error in the log:
Code:

Starting local server: starccm+ -server -cpubind -rsh ssh -machinefile D:\Work\MachineFile.txt -np 112
mpirun: Drive is not a network mapped - using local drive.

"C:\Program Files\CD-adapco\STAR-CCM+11.04.012-R8\mpi\platform\9.1.4.0\windows\bin\mpirun.exe"  -aff=automatic:bandwidth  -np 112  -hostfile D:\Work\MachineFile.txt "C:\Program Files\CD-adapco\STAR-CCM+11.04.012-R8\star\bin\starccm+.exe"  -cpubind  -node

Length of the last string is 253 symbols - which seem to be too long, but - it successfully starts on 3 nodes (using "Parallel on named hosts" or "Machine File" with 3 nodes listed - both) with the following command:
Code:

"C:\Program Files\CD-adapco\STAR-CCM+11.04.012-R8\mpi\platform\9.1.4.0\windows\bin\mpirun.exe"  -aff=automatic:bandwidth  -np 84  -hostlist NodeA:28,NodeB:28,NodeC:28 "C:\Program Files\CD-adapco\STAR-CCM+11.04.012-R8\star\bin\starccm+.exe"  -cpubind  -node
which has a length of 260 symbols!


PS2 Obviously, I can reinstall Star to shorter path - like C:\StarCCM+ instead of C:\Program Files\CD-adapco\STAR-CCM+11.04.012-R8, - but that doesn't seem to be the case.

Has anyone got any ideas or maybe has experienced the problem before?
