Subject: [OMPI users] misleading error message in openmpi-1.6.2rc5r27346
From: Siegmar Gross (Siegmar.Gross_at_[hidden])

yesterday I installed openmpi-1.6.2rc5r27346 and it seems to work.
Unfortunately I get a misleading error message when I call "mpiexec"
with an unknown option.

tyr fd1026 112 mpiexec -np 2 -host sunpc0 -report-bindings -bycore \
  -bind-to-core date

tyr fd1026 113 mpiexec -np 2 -host sunpc0 -report-bindings -map-by core \
   -bind-to-core date
mpiexec was unable to launch the specified application as it could not find an executable:

Executable: -map-by
Node: sunpc0

while attempting to start process rank 0.
2 total processes failed to start

Is it possible to display an error message like "unknown option"?

Kind regards
