SYMPTOM:
When running the CFX Solver in PVM distributed parallel mode, and a Windows 64bit machine is used as a slave, the run fails with an error message similar to the following:
+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The solver executable D:Ansys |
| Incv110CFXbinwinntsolver-pvm.exe on host twin64 could not be |
| found, or is not readable. Check that the executable is readable |
| by the user running the rsh service. |
+--------------------------------------------------------------------+
PROBLEM:
There are two problems associated with using Windows 64 machines as slaves in a PVM distributed parallel run.
The first is due to an errror in the machine type returned by the slave machine leading to the above error message. If the platform for the host is not explicitly set in the hosts.ccl file, the slave incorrectly reports the machine type as Windows32 and the job fails as a result. To correct this simply add the relevant details to the hosts.ccl file.
However, even with this correction, subsequent jobs may still fail with the following error message:
+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| Unable to start the PVM daemon on host twin64. This may indicate |
| that the PVM daemon is already running on that host, or that it |
| left files in /tmp on that host because it did not exit cleanly |
| last time it was run. |
+--------------------------------------------------------------------+

WORKAROUND: No workaround is currently available. FIXED IN: ANSYS CFX Release 11.0Service Pack 1. |
