# Increase the number of allowed incomming ssh connections to support many mpirun applications
# attempting to hit a mpi host/worker (i.e. rabbit node) all at once. A compute node has 192 cores,
# and each rabbit has 16 compute nodes. This means 3072 (192*16) ssh connections could come in at
# once. Round to the nearest power of 2 for good measure.
