The Centre for Development of Advanced Computing (C-DAC) was founded in March 1988 as part of the Department of Electronics (now the Department of Information Technology). C-DAC was originally developed due to the United States' refusal to sell India a Cray supercomputer during the 1980s. The first C-DAC supercomputer, the PARAM 8000, was introduced in 1991; it had the capacity to perform a billion calculations per second. This was followed by the PARAM 9000 in 1996 and the PARAM 10000 in March 1998. These C-DAC supercomputer models were reportedly used to design the nuclear weapons tested in May 1998. In the aftermath of these tests, C-DAC was targeted for sanctions by the US Department of Commerce. US sanctions not only barred C-DAC from buying materials for nuclear or military applications, but also blocked the sale of Export Administration Regulation (EAR) 99 items that included non-sensitive, non-strategic, and non-dual-use item goods.

In November 2002, C-DAC introduced the PARAM Padma, its first trillion floating point operations per second (tereflop) supercomputer. By April 2003, C-DAC had expanded on this technology to develop a terascale supercomputer. This effectively made India one of the five countries in the world to indigenously produce this sophisticated computing system (the others being the United States, Japan, Israel, and China). In addition to the development of the PARAM supercomputer series, C-DAC also manages the Advanced Computing Training School (ACTS), which has branches in several Indian cities with an annual enrollment of 30,000 students.
