The latest addition to the ICTS HPC facility is the 2048-cores Intel cluster. This cluster is composed of 64 nodes, installed in the ICTS data center. Of the sixty-four, one head node and all others are execution nodes. This is a homogeneous cluster with each node consisting of 64 processing cores with hyperthreading enabled. The cluster nodes are connected using Intel Omnipath switches.
Hardware Overview:
The cluster has 64 nodes and the hardware configuration for each node is as follows:-
-
Compute Nodes:
- Intel® Xeon® Processor Gold 6130, 2 processors (16 cores each) operating at 2.1 GHz clock speed
- 192 GB Main Memory DDR4 ECC SDRAM
- 1000GB SATA 6Gbps HDD for OS and system software
- Network: Intel Omnipath (3:1 blocking)
-
Master Node:
- Intel® Xeon® Processor Gold 6130, 2 processors (16 cores each) operating at 2.1 GHz clock speed
- 384 GB Main Memory DDR4 ECC SDRAM
- 2 x 400 Gb Enterprise SSD for OS and system software
- Network: Intel Omnipath (3:1 blocking)
-
Storages:
- Network Attached Storage of 500 TB capacity usable after the RAID
- Parallel File System (PFS)
- Based on BeeGFS parallel file system
- Total usable capacity 150 TB primary storage
- Throughput 5 GB/s
- Archiving Storage: Network Attached Storage of 550 TB capacity usable after the RAID

Operating system
Each computing and master node runs the CentOS Linux operating system, version 7 and you’ll have to interface with them by using the command line.
Thus, you are more than encouraged to become familiar – if not yet – with Linux commands. We can recommend the following sites and resources:
