CAMS/Math Computation Laboratory

High quality facilities supporting numerical computation are essential for the Department of Mathematical Sciences and the Center for Applied Mathematics and Statistics (CAMS) at NJIT to fulfill their educational and research missions.

Thus DMS and CAMS, with the help of SCREMS, CSUMS, UBM, and MRI grants from NSF, together with the generous support of NJIT, have maintained the CAMS Math Computation Laboratory (CMCL) for the research needs of their members since 1989.

Computational support provided by CMCL for the proposers consists of the workstations and desktop PC’s that are networked and available to investigators in their offices, plus other more major, shared facilities of the CMCL (see Table 1).

The DMS has expanded its “Stheno” cluster in stages since its first server became operational in 2011. The cluster is intended to be used to test, debug, and run message-passing interface (MPI) codes. It now has 32 nodes and 392 cores, 3,840 GB of RAM, and 9,872 GB of local disk storage. Two servers of the cluster contain GPU’s, which now total 6, with a total of 32 GB of GPU RAM. The GPU’s are currently CUDA capable and are intended for general purpose computation on GPU-accelerated computing nodes.

The DMS also has its “Gorgon” cluster, which has been expanded sequentially since it became operational in 2010. This cluster is intended for jobs that require large memory, and for parallel computations that use the OpenMP application programming interface. It is now a 32 core system, with AMD Opteron 6134 processors running at 2.3 GHz, and a total of 64 GB of shared memory.

All computational facilities are maintained by the Academic and Research Computing Systems (ARCS) group, headed by its director, David Perel.

Recognizing the need to support the scientific and engineering computing that is essential to research efforts across the campus, NJIT provides all faculty, postdocs, and graduate students access to centralized computing servers for research purposes. These recently received a significant upgrade as part of a substantial donation by Linode, which is a Linux-based cloud hosting company based in New Jersey. The NJIT cluster, “Kong”, now has a total of 359 nodes, 2,812 CPUs, 22,704 GB of RAM, and a disk storage of 318,800 GB. Processors are all AMD Opteron or Intel Xeon models, with speeds from 2.2 GHz to 2.8 GHz. It also features two 2-GPU nodes (NVIDIA Tesla K20x). Each GPU has 2,688 cores, with a peak performance double precision rate of 1.31 Tflops, and 6 GB of RAM.
