29 The IUCAALibrary The IUCAA library provides users access to a comprehensive collection of books and journals in astronomy, astrophysics, and related areas. The library acquired 64 new print titles and 361 eBooks from the Springer Physics and Astronomy collection for 2023-24 and renewed the subscription to Annual Reviews. The library maintained its renewals to the Grammarly Premium software and Overleaf, the collaborative cloud-based LaTeX editor for writing, editing and publishing scientific documents. The library renewed its subscriptions to 63 journals for 2023. In addition to e-journal subscriptions, the library continued to receive access to seven e- resources, courtesy of the E-Shodh Sindhu Consortium for Higher Education Electronic Resources, MHRD, Government of India and two NDL e-resources as listed below: 1. American InstituteofPhysics 2. AmericanPhysical Society 3. I ns t i tute for Stud i es i n I ndus t r i a l Development (ISID)Database 4. JGatePlus (JCCC) from IUCAA and various Indian Universities, running applications for Molecular Scattering, Molecular Dynamics, Stellar Dynamics, Gravitational N-Body Simulations, Cosmic Microwave Background Evolution, Fluid Mechanics, Magnetohydrodynamics, Plasma Physics, and the analysis of diverse astronomical data. The Sarathi Cluster is primarily used for gravitational wave research and is mostly used by national and international members of the LIGO Scientific Collaboration (LSC), which includes many IUCAA members and Associates. The cluster is comprised of heterogeneous compute servers, it is built in three phases. The cluster consists of more than 8000 Physical cores. The theoretical peak performance of the compute node CPUs of the cluster is nearly 530 TFlops. The cluster has 2PiB PFS storage with 30Gbps write and read (1:1) throughput The Vroomcluster is used solely for the MeerKAT Absorption Line Survey (MALS). This cluster has 21 compute nodes, 2MDS nodes, 4 GPU notes and 2 head node which delivers 25 TF computing speed and has a parallel file system of 3.5 PiB usable capacity attached to it. The cluster is also attached to 2 PiB archival storage for archiving/serving the processed data to international community. Sarathi Cluster Phase III, Pegasus Cluster, and Sarathi Cluster Phase II are listed at 36th, 50th and 53rd rank respectively in the list of top Supercomputers in India published on January 31, 2024. The list is maintained and supported by CDAC's Terascale Supercomputing Facility (CTSF), CDAC, Bangalore. The list is available at HPC clusters listed in Top Supercomputers in India https://topsc.cdacb.in/filterdetailstry?page=60 &slug=January2024
