System Status: UP
System Temporary Change:
Due to some changes we are making to the GPC GigE nodes, if you run multinode ethernet MPI jobs (IB multinode jobs are fine), you will need to explicitly request the ethernet interface in your mpirun:
For Openmpi -> mpirun --mca btl self,sm,tcp
For IntelMPI -> mpirun -env I_MPI_FABRICS shm:tcp
There is no need to do this if you run on IB, or if you run single node mpi jobs on the ethernet (GigE) nodes. Please check GPC_MPI_Versions for more details.

All systems are back up. Please resubmit your jobs.

Chiller failure, all systems automatically shut down. We'll keep you informed in this space.
