The HPCC operates the following computer systems:

ANDY is named in honor of Dr. Andrew S. Grove, a City College alumnus and one of the founders of the Intel Corporation. It is an SGI cluster with 744 processor cores. ANDY is for jobs using 64 cores or fewer and for Gaussian jobs.

BOB is named in honor of Dr. Robert E. Kahn, an alumnus of the City College, who, along with Vinton G. Cerf, invented the TCP/IP protocol. BOB is a Dell cluster with 232 processor cores. BOB supports users running Gaussian09; no other applications are supported on BOB.

CHIZEN is named in honor of Bruce Chizen, former CEO of Adobe, and a Brooklyn College alumnus. CHIZEN is the system that is used as a gateway to the above HPC systems. It is not used for computations.

KARLE is named in honor of Dr. Jerome Karle, an alumnus of the City College of New York who was awarded the Nobel Prize in Chemistry in 1985. KARLE is a Dell shared memory system with 24 processor cores. KARLE is used for serial jobs, Matlab, SAS, parallel Mathematica, and certain ARCview jobs. It is the only system that supports running interactive jobs relying on graphical user interface.

PENZIAS is named in honor of Dr. Arno Penzias, a Nobel Laureate in Physics, and a City College alumnus. PENZIAS is a cluster with 1,152 Intel Sandy Bridge cores each with 4 Gbytes of memory. It is divided into 2 virtual nodes, one with 12 cores and no GPUs and one with 4 cores and 2 GPUs. It is used for applications requiring up to 128 cores. It also supports 136 NVIDIA Kepler K20 accelerators.

SALK is named in honor of Dr. Jonas Salk, the developer of the first polio vaccine, and a City College alumnus. It is a Cray XE6m with a total of 1,028 processor cores. SALK is reserved for large parallel jobs, particularly those requiring more than 64 cores. Emphasis is on applications in the environmental sciences and astrophysics.

ZEUS is a Dell cluster, used exclusively to support classroom and training activities.

Detailed information on each of these systems is available on the CUNY HPCC wiki.
