Roughly 1/3 of the TCS nodes thermal-checked themselves off ~1140 today due to a glitch in the water supply temperature. Unfortunately, all jobs running on those nodes were lost. Please check your jobs and resubmit if necessary.

System Temporary Change for MPI ethernet jobs:
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.
