Intel Paragon OSF/1 AD on the Paragon's compute processors. Oak Ridge National Laboratory operated a Paragon XP/S 150 MP, one of the largest Paragon systems, for several years. The prototype for the Intel Paragon was the Intel Delta, built by Intel with funding from DARPA and installed operationally at the California Institute of Technology in the late 1980s with funding from the National Science Foundation. The Delta was one of the few computers to sit significantly above the curve of Moore's Law. The computer boards was produced in two variants: the GP16 with 16 MB of memory and two CPUs, and the
Doubling time million by 2084. The notion of doubling time dates to interest on loans in Babylonian mathematics. Clay tablets from circa 2000 BCE include the exercise "Given an interest rate of 1/60 per month (no compounding), come the doubling time." This yields an annual interest rate of 12/60 = 20%, and hence a doubling time of 100% growth/20% growth per year = 5 years. Further, repaying double the initial amount of a loan, after a fixed time, was common commercial practice of the period: a common Assyrian loan of 1900 BCE consisted of loaning 2 minas of gold, getting back 4
