 In 1980s and 1990s, the scientific research and mathematical work on the supercomputers was also carried out by mathematician Dr. Tasneem Shah at the Kahuta Research Laboratories while trying to solve additive problems in Computational mathematics and the Statistical physics using the Monte Carlo method.In 1990s, the Khan Research Laboratories deployed a series of supercomputer systems at its site, becoming nation's one of the first fastest computers at that time.Technological imports in supercomputers were denied to Pakistan, as well as India, due to an arms embargo, as the foreign powers feared that the imports and enhancement to the supercomputing development was a dual use of technology and could be used for developing nuclear weapons in 1990s.
