OPTIMUM Cluster

SLIM’s OPTIMUM HPC Cluster

In 2014, with the support of the Natural Sciences and Engineering Research Council of Canada (NSERC), and with matching support of SINBAD sponsors ION, CGG, Schlumberger and Sub Salt Solutions, SLIM acquired an SGI Linux HPC cluster (based on Intel’s Ivy Bridge 2.8 GHz E5-2680v2 processor) with cumulative theoretical peak floating-point performance of 25 Tflops.

The compute subsystem of the cluster comprises 1120 CPU cores. The high-speed inter-processor communication utilizes FDR Infiniband network at 56 Gbs. Storage subsystem consist of 176 TB high-throughput Lustre distributed parallel file-system over the Infiniband network and 6 TB of NFS storage over Ethernet network.

OPTIMUM cluster has 600 licenses for MATLAB distributed computing server.  The system's dedicated use is for research, development, and testing of SLIM’s algorithms.
