Kohinoor 2

Introduction

Kohinoor 2 is the second High Performance Computing (HPC) cluster installed at TIFR-TCIS Hyderabad. This cluster is composed of 33 nodes, in which one is a head node and all other are execution nodes. This cluster is composed of 1 head node, 32 CPU nodes and 50 TB NAS storage. The cluster nodes are connected using Infiniband HBAs through a 36 port completely non blocking Intel truscale QDR Interconnect infiniband (IB) switch. The cluster is managed by the open source batch scheduler “Open Grid Engine” software for job scheduling and load balancing. The head-node allows user logins for job submission in cluster. The cluster has a local Network Attached Storage (NAS) of 50 TB across the nodes through IB switch, which is used for computational runs.
