Kohinoor 1

Kohinoor 1 is the first High Performance Computing (HPC) cluster installed at TIFR-TCIS Hyderabad. This cluster is composed of 17 nodes, in which one is a head node and all other are execution nodes. This cluster is a heterogenous cluster which is composed of 12 CPU nodes and nodes and 4 CPU nodes with 2 Fermi M 2090 GPUs per node. The cluster nodes are connected together through a completely non blocking Mellanox 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 40 TB connected across the nodes through IB switch, which is used for computational runs and a 36 TB NAS is attached to the head node of the cluster for the purpose of archiving and post-processing of data.

Kohinoor 2

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 together through a 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 connected across the nodes through IB switch, which is used for computational runs.

Kohinoor 3

Kohinoor 3 is the third HPC cluster in the Kohinoor tetralogy of clusters in TIFR – TCIS, Hyderabad, which was installed and operational from September 2016.
This cluster is composed of 69 nodes, in which one is a head node and all other are execution nodes. This cluster is a heterogeneous cluster which is composed of 64 CPU nodes and nodes and 4 GPU nodes with 4 Nos of Nvidia Tesla K40 per node. The cluster nodes are connected together through a completely non-blocking Mellanox FDR Interconnect InfiniBand (IB) switch. The cluster is managed by the open source batch scheduler “SLRUM” software for job scheduling and load balancing. The head-node allows user logins for job submission in cluster. The cluster has a locally attached Parallel File System (Open source Lustre) of 200 TB connected across the nodes through IB switch, which is used for computational runs and another 200 TB NAS is attached to the head node of the cluster for the purpose of archiving and post-processing of data.

Kohinoor 4

Kohinoor 4 is the fourth HPC cluster in the Kohinoor tetralogy of clusters in TIFR – TCIS, Hyderabad, which was installed and operational from May 2019.
This cluster is composed of 90 nodes, in which two of them are head nodes and all the other are execution nodes. This cluster is composed of 88 CPU nodes with 32 cores per node. The cluster nodes are connected together through a completely non-blocking Intel OmniPath (OPA) switch. The cluster is managed by the open source batch scheduler “PBS Pro” software for job scheduling and load balancing. The head-node allows user logins for job submission in the cluster. The cluster has a locally attached ZFS File System of 200 TB connected across the nodes through OPA switch, which is used for computational runs and another 400 TB ZFS storage is attached to the secondary head node of the cluster for the purpose of archiving and post-processing of data.
