[mpich-discuss] UNUSUAL MPICH-2 ERROR

[Sticks Mabakane]

Dear Jeff,
 
We are currently moving our Blue Gene system from Loadleveler resource manager to Moab Scheduling system. The Moab is currently running very well with Slurm in Blue Gene but the problem is the mpi. Unfortunately; all the mpi wrappers in /bgsys/drivers/ppcfloor/comm/bin/ were compiled against Loadleveler libraries. Is there any Blue Gene documentation that you think it may help me?
 
Regards,
 
Sticks

You should not install have to install MPICH2 on any Blue Gene system.
Please look in /bgsys/drivers/ppcfloor/comm/bin/ for the mpi*
compiler wrapper scripts.  If they are not present, please follow the
IBM documentation on how to install the system software via RPM.  Do
not try to install MPI on a Blue Gene by downloading the latest
MPICH2.

Jeff
