PVM RSH parallel setup problem Windows XP

abe

I am trying to set up 2 Windows XP SP1 PC's to run PVM distributed parallel runs on ANSYS CFX 10 with ServicePack1. I have setup my hosts.ccl file to include the slave node as follows.

EXECUTION CONTROL: PARALLEL HOST LIBRARY: HOST DEFINITION: MASTER

Installation Root = C:\Program Files\Ansys Inc\CFX\CFX-10.0

Host Architecture String = intel_opteron.sse2_winnt5.1 END # HOST DEFINITION MASTER HOST DEFINITION: SLAVE

Installation Root = C:\Program Files\Ansys Inc\CFX\CFX-10.0

Host Architecture String = intel_p4.sse2_winnt5.1 END # HOST DEFINITION SLAVE END # PARALLEL HOST LIBRARY END # EXECUTION CONTROL

I copied the automatically-created PVMhosts file from C:\Temp into the <CFXROOT>\config folder, and it is setup as follows.

&MASTER dx=C:\Program Files\Ansys Inc\CFX\Shared\pvm3.4.4_11-1\lib\WIN32\pvmd3.exe &SLAVE dx=C:\Program Files\Ansys Inc\CFX\Shared\pvm3.4.4_11-1\lib\WIN32\pvmd3.exe

No problems adding the SLAVE under the solver definition, but I get an error from the Solver output...

+--------------------------------------------------------------------+ | An error has occurred in cfx5solve: | | | | Unable to start the PVM daemon on host CLYDESDALE. 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. | +--------------------------------------------------------------------+

Checking in the help files, I launched the PVM console and tried to manually add the SLAVE node (add SLAVE) but it gives me an error along the lines of...

socket closed (?) after reading from : The system cannot find the file specified. socket closed (?) after reading from SLAVE: Error doing $PVM_ROOT/lib/pvmd -s -d0x0 -nSLAVE 1 etc etc etc phase1() rsh failed for hose SLAVE p1_startup() got result "PVMCantStart" for SLAVE phase1() etc etc etc (it re-tries and fails again).

Then the console window gives an error which includes the statement... Auto-diagnosing Failed Hosts... SLAVE... Verifying Local Path to "rsh"... Error - File C:\WINDOWS\system32\rsh Not Found! Determine the path to the "rsh" command on your system, and edit PVM_ROOT\conf\WIN32.def to adjust the path for the -DRSHCOMMAND=\"\" flag. Then recompile PVM and your applications.

Keep in mind, I DO have the RSH service installed, and functional, under the same login name, on the SLAVE machine. I can test it from MASTER with the Echo command.

Sorry for this long post, but I really don't know what to do now. I've looked through the old posts (ca 2002) about RSH and PVM problems on CFX5 but I can't seem to get my system to work. Could it have something to do with the spaces in the install directory names?

Any help would be appreciated.
