KNOWN ISSUE: "cfx5parhosts -benchmark" does not work on Windows platforms
|
SYMPTOM: Executing the command "cfx5parhosts -benchmark" on a Windows machine results in output similar to the following: Running benchmark with 1 partitions. For best results, ensure that no other jobs are running on this machine while the benchmark is running. An error has occurred in cfx5parhosts: The ANSYS CFX solver exited with return code 128. No results file has been created. An error has occurred in cfx5parhosts: Error finding the total CPU time in the ANSYS CFX solver output file <folder>Benchmark_001.out: perhaps the job did not complete properly. PROBLEM: The "cfx5parhosts -benchmark" command allows the determination of the relative speed of a machine by running a benchmark case. On Windows platforms, where the HP MPI-based solver is used by default, the cfx5parhosts script does not set up the path correctly to pick up some required HP MPI libraries. WORKAROUND: Add the following folder to the path: <CFXROOT>toolshpmpi-win-1.1-1bin On most Windows machines the path can be set temporarily inside the Command Prompt itself, just for the purposes of running the benchmark. This can be done by opening the CFX Launcher, selecting Tools > Command Line, and then typing: path %path%;C:Program FilesANSYS Incv121CFXtoolshpmpi-win-1.1-1bin cfx5parhosts -benchmark assuming the default ANSYS installation path. FIXED IN: No fix is currently available. |
