System Architecture

Param Yukti is based on a heterogeneous configuration consisting of Intel Xeon Cascade lake CPUs and NVIDIA Tesla V100 GPUs. The system is designed and built by the HPC Technologies team, Centre for Development of Advanced Computing (C-DAC).


The compute nodes of Param Yukti are connected by InfiniBand HDR 100 Gbps high speed network and a secondary network for support and maintenance. The network topology is shown in the figure below.


The storage subsystem comprises of the following components:

  • 2x ES7990 Embedded Lustre Parallel File System storage appliance
  • 12x 1.92 TB SAS SSD drives for metadata pool
  • 164x 10 TB 7.2K drives for 2 x data pool (with 1x MR)

Software Stack

Software stack is an aggregation of software components that work in tandem to provide support for utilizing the computing resources through different means. The software stack has three layers: (i) the kernel and hardware drivers, (ii) middleware applications, management tools, etc., and (iii) application libraries, programming tools and computational software. Param Yukti supports all major programming languages and tools. For a list of available software see the resources section.
