[molpro-user] parallel 2006.1 on Opteron/myrinet cluster

[Kirk Peterson]

All,

after rebuilding both the myrinet and mpich software on this system,  
the problem now changes to:

Last System Error Message from Task 1:: No such file or directory
[1] MPI Abort by user Aborting program !
[1] Aborting program!

Molpro jobs work fine on a single processor and all mpi and ga test  
programs seem to run ok.  Any ideas
on what file or directory either ga or molpro cannot find?

regards,

Kirk
