The C-DAC was created at some point between November 1987 and August 1988. C-DAC was given an initial 3 year budget of Rs 375 million to create a 1000MFLOPS (1GFLOPS) supercomputer by 1991. C-DAC unveiled the PARAM 8000 supercomputer in 1991. This was followed by the PARAM 8600 in 1992/1993. These machines demonstrated Indian technological prowess to the world and led to export success. Param 8000 was replicated and installed at ICAD Moscow in 1991 with Russian collaboration.
The PARAM 8000 was considered a success for C-DAC in delivering a gigaFLOPS range parallel computer. From 1992 C-DAC undertook its "Second Mission" to deliver a 100 GFLOPS range computer by 1997/1998. The plan was to allow the computer to scale to 1 teraFLOPS. In 1993 the PARAM 9000 series of supercomputers was released, which had a peak computing power of 5 GFLOPS. In 1998 the PARAM 10000 was released; this had a sustained performance of 38 GFLOPS on the LINPACK benchmark.
By the early 2000s it was noted that only ANURAG, BARC, C-DAC and NAL were continuing development of their supercomputers. NAL's Flosolver had 4 subsequent machines built in its series. At the same time ANURAG continued to develop PACE, primarily based on SPARC processors.
The Indian Government has proposed to commit US$2.5 billion to supercomputing research during the 12th Five-Year Plan period (2012–2017). The project will be handled by Indian Institute of Science (IISc), Bangalore. Additionally, it was later revealed that India plans to develop a supercomputer with processing power in the exaflops range. It will be developed by C-DAC within the subsequent five years of approval.
The aim is to create a cluster of geographically distributed high-performance computing centers linked over a high-speed network, connecting various academic and research institutions across India. This has been dubbed the "National Knowledge Network" (NKN). The mission involves both capacity and capability machines and includes standing up three petascale supercomputers.
The first phase involved deployment of supercomputers which have 60% Indian components. The second phase machines are intended to have an Indian designed processor, with a completion date of April 2021. The third and final phase intends to deploy fully indigenous supercomputers, with an aimed speed of 45 petaFLOPS within the NKN.
By October 2020, the first assembled in India supercomputer had been installed. The NSM hopes to have the manufacturing capability for indigenous production by December 2020.
A total of 24.83 petaFLOPS of High Performance Computing (HPC) machines were put into service between 2019 and 2023. In addition to 5,930 specialists from more than 100 institutes using the newly constructed facilities, 1.75 lakh (175,000) people received training in HPCs. A total of 73.25 lakh (7.325 million) computational high performance queries were run. Seven systems with processing power greater than one petaFLOPS, eight systems with computational capacities between 500 teraFLOPS and 1 petaFLOPS, and thirteen systems with capacities between 50 teraFLOPS and 500 teraFLOPS were installed during this time.
