I removed the RedHat LAM/MPI and all tests pass with flying colors. I checked for other RedHat RPMs that may conflict with the OSCAR distros and that remained installed after the OSCAR installation completed and there are several of them, such as PVM. Should these have been removed by the OSCAR installation process? Should they be removed? My guess is yes. > Running the test scripts outside the test environment will invariably not > work well.

Is there anything I should be concerned about with regard to running OSCAR 1.4 under RH 7.1? Any known problems that may arise down the road?
