33 rd ANNUAL REPORT 2020-21 157 FACILITIES AT IUCAA Computing Facility 1) High Performance ComputingCluster (Pegasus) Storage Expansion 2) High Performance ComputingCluster (SARATHI) Storage Expansion 3) High Performance ComputingCluster (Vroom) Storage Expansion 4) Wired LAN Connectivity in Housing Colony The IUCAA Computing Facility continues to offer the state-of-the-art computing hardware and technology rich mobile work space for IUCAAmembers, associates and visitors. It also extends an array of specialized High Performance Computing (HPC) environments to the academic community for their research. The hardware and devices currently managed by the computing facility include 340 servers and desktops, 90 laptops, 80 printers and scanners, three large HPC systems and over 7 Petabyte of storage, in addition to diverse equipments deployed for an extensive, high throughput wired and wireless campus-wide network. The number of registered WiFi devices is over 900, and e-mail accounts served by the computing facility amount to nearly 600. IUCAAhas its own registered domain name as “iucaa.in ”. TheWAN services are provided by the National Knowledge Network on a 1 Gbps fibre connectivity, with a fallback arrangement on a 50 Mbps line from TataVSNL. During the year emphasis was given to implementation of the following: The demand for HPC cluster storage is increasing steadily. The storage of Perseus cluster was about 85% occupied within 18 months of its operation. Hence, to serve the computing requirement, we have expanded the storage attached toHPCPegasus cluster by 1PB. In the current year, 2PiB PFS storage with 30Gbps write and read (1:1) throughput has been added to the cluster from the LIGO - India funds. This will help to maintain most of the data from the LIGO - Virgo - KAGRAdetector network at IUCAA. The MeerKAT Absorption Line Survey (MALS), led by IUCAA scientists, is one of the ten extensive surveys being carried out with the MeerKAT telescope in South Africa. The data are being transferred from South Africa to IUCAA through transportable media (tapes and disks) for processing at IUCAA by the MALS team. Currently, the MALS cluster was equipped with 1 PB usable storage. However, the data processing in last a few months has exhausted about 90% of the storage. Hence, in order to continue uninterrupted data processing, we have extended MALS storage by 1.5 PB. During the lockdown period, most of the faculty, students, and staff in the housing colony have been working from home. In order to facilitate this, we have enhanced the coverage of wired LAN
