Gen1 (Rudra-I)

Under the build approach C-DAC has designed and developed a compute server “Rudra” as one of the most important subassemblies required for Supercomputers. Rudra, C-DAC’s indigenous server platform features Intel Xeon 2nd Generation Cascade Lake processor supporting DDR4 memory, with two expansion slots for GPU and Accelerator cards. C-DAC is in process of deploying HPC Systems across the nation with compute performance totalling 40PF, based on Rudra Servers called PARAM Rudra.

C-DAC has partnered with EMS partners in India for mass manufacturing of Rudra servers. More than 1300 servers have been produced so far and are getting deployed at different installation sites. Under transfer of technology agreement, C-DAC has also transferred the Rudra Server Design to three industry partners, viz. M/s VVDN, M/s Kaynes technologies and M/s Avalon technologies. All these activities have catalysed the development of entire eco-system right from design, manufacturing and userbase generation.
