A project for developing an HPC facility with PetaFlop computing capacity for conducting a real-time commensal search for Fast Radio Bursts (FRBs) and pulsars with the GMRT is funded under the National Supercomputing Mission (NSM). The Centre for Development of Advanced Computing (CDAC) and NCRA have signed a Memorandum of Understanding (MoU) to jointly build the data centre to host 60 of CDAC's indigenously developed Rudra servers hosting 90 A100 GPUs, 10s TB memory and 2 PB storage.
