In September 2020, OSC installed an additional 398 Intel\u00ae Xeon\u00ae \u2018Cascade Lake\u2019 processor-based nodes as part of an expansion cluster and reached full production status on Tuesday, September 22, 2020.<\/p>\n<p>This expansion approximately triples the peak capacity of the original Pitzer cluster (which includes 260 Intel\u00ae Xeon\u00ae \u2018Skylake\u2019 processor-based nodes), adding 3.8 petaflops. Below is a summary of the hardware information:<\/p>\n<ul>\n<li>340\u00a0\u201cdense compute\u201d nodes (48 cores, 192GB RAM)<\/li>\n<li>42 Dual GPU nodes (48 cores, 384GB RAM, 2 V100 32GB GPUs)<\/li>\n<li>4 Quad GPU\u00a0nodes (48 cores, 768GB RAM, 4 V100 32GB GPUs)<\/li>\n<li>12 large memory nodes\u00a0(48 cores, 768GB RAM)<\/li>\n<\/ul>\n<p>In addition, OSC switched to Slurm\u00a0for job scheduling and resource management on Pitzer, replacing the Torque\/Moab environment. OSC also enabled a PBS compatibility layer\u00a0in order to make the transition as smooth as possible.\u00a0For more information on the migration, you can visit\u00a0<a href=\"https:\/\/www.osc.edu\/supercomputing\/knowledge-base\/slurm_migration\">this informational page<\/a>.
