Make sure you're using the right mpirun -- you might have multiple installed on your machine. OMPI's "mpirun --help" definitely includes a description of the --mca parameter: -mca|--mca <arg0> <arg1> Pass context-specific MCA parameters; they are considered global if --gmca is not used and only one context is specified (arg0 is the parameter name; arg1 is the parameter value) -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
