HIGHLIGHTS 

The overall supercomputing capability of Param Pravega is 3.3 petaflops.

The majority of its components were made and assembled in India.

Param Pravega now has a storage capacity of 4 petabytes.

WHY IN NEWS 

The Indian Institute of Science (IISc) has constructed a new supercomputer that is said to be one of the nation's most capable. It is said to be the largest supercomputer at an accredited university, and it was inaugurated by Param Pravega and developed under the National Supercomputing Mission (NSM). The Param Pravega supercomputer at IISc is said to have a total high performance computing capability of 3.3 petaflops (1 petaflop equals quadrillion operations per second). Many of the parts of Param Pravega were made and assembled in India. According to IISc, it is 'intended to fuel different research and educational endeavours.' The Indian Institute of Science (IISc) has finally deployed and activated a new supercomputer called Param Pravega, according to a release. The new supercomputer has a maximum computational capability of 3.3 petaflops, as previously stated. The Center for Scientific and Industrial Research created Param Pravega (C-DAC).

SPECIFICATIONS OF PAEAM PRAVEGA :

The nodes of Param Pravega are heterogeneous, using Intel Xeon Cascade Lake CPUs and Nvidia Tesla V100 GPUs. The ATOS BullSequana XH2000 series machine has a peak supercomputing capability of 3.3 petaflops. 11 DCLC racks of compute nodes, two service racks of Master/Service nodes, and four storage racks of DDN storage make up Param Pravega. Two master nodes, 11 login nodes, two firewall nodes, four administration nodes, one NIS slave, and 624 compute — CPU + GPU — nodes make up Param Pravega's node setup. Regular CPU nodes, high-memory CPU nodes, and GPU nodes are the three types of nodes that have been created. In Param Pravega, there are 40 GPU nodes with 2.5GHz Intel Xeon G-6248 CPUs and the same RAM and storage configuration as the conventional CPU nodes. Each node's GPU is made up of two Nvidia V100 Tesla (HBM2 device memory) GPUs with a total capacity of 16GB. Regular CPU nodes get Intel Xeon Cascade Lake 8628 CPUs with 48 cores, 192GB RAM, and a 480GB SSD in a two-socket configuration. There are 428 normal CPU nodes in Param Pravega. The high-memory CPU nodes of IISc's supercomputer each have 768GB of RAM, and there are 156 of them.

The pin is connected Lustre disk with a throughput capacity of 100GB per second provides 4 petabytes of space to Param Pravega. The supercomputer runs the CentOS 7.x Linux software. On GPU nodes, the system additionally receives CUDA and OpenAAC SDKs. Mathematics, scientific, and application libraries such as Intel-MKL, GNU Scientific Library, HDF5, NetCDF, and a variety of Python-based mathematical and data processing libraries are also available from Param Pravega. This isn't the first supercomputer at IISc. It bought SahasraT in 2015, and it was India's fastest supercomputer at the time. SahasraT has been employed by IISc to study COVID-19 and other infectious disorders. Many of the studies that have used SahasraT include simulations of turbulent flows for green energy systems, as well as climate change and its consequences.
