Welcome to the High Performance Scientific Computing facility at the Harish-Chandra Research Institute, Allahabad. A set of Linux clusters form the core of this facility. Starting in the year 2000, we have been setting up and using Linux clusters for high performance scientific computing.The HPC facility has 4 serial/distributed memory clusters and 1 QDR parallel cluster with about 350 TB of associate storage. Two additional clusters will be set up during the XII plan period and associated networking and storage facilities enhanced accordingly.
