Thanking you ---------------------------------------------------------------------- >Comment By: Jeff Squyres (jsquyres) Date: 2003-11-23 08:09 Message: Logged In: YES user_id=11722 You will always have to create users in order to run MPI jobs; this has not changed since OSCAR 2.2.x. Specifically, LAM/MPI will not allow itself to be run as root (for security reasons). Hence, you have to create a non-root user and propagate that user out to all the nodes before you can use LAM properly. I am not 100% certain, but I believe that MPICH does not require this. However, I would strongly recommend against running MPI or PVM programs as root (which is exactly why LAM/MPI disallows this behavior). I don't know what you are referring to about a GUI being launched when you logon to the head node; OSCAR does not automatically launch any GUI. You'll have to be a bit more specific about what the program is. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=109368&aid=845264&group_id=9368 ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
