Pitzer expansion and slurm migration

OSC has expanded Pitzer Cluster approximately tripling the peak capacity. A summary of the expansion: 340 "dense compute" nodes (48 cores, 192GB RAM), 42 Dual GPU nodes (48 cores, 384GB RAM, 2 V100 32GB GPUs), 4 Quad GPU nodes (48 cores, 768GB RAM, 4 V100 32GB GPUs), 12 large memory nodes (48 cores, 768GB RAM) Please see the following page for information on requesting the different types of nodes on pitzer: https://www.osc.edu/resources/technical_support/supercomputers/pitzer/guidance_on_requesting_resources_on_pitzer OSC also switched to Slurm for job scheduling and resource management on Pitzer, replacing the Torque/Moab environment. We enabled a PBS compatibility layer in order to make the transition as smooth as possible.
