Blief History of PACS/PAX Computers
Project of PACS/PAX computers was started at Kyoto University in 1977 by Tsutomu Hoshino. The first and second machines PACS-9 and PAX-32 were made at Kyoto University in 1978 and 1980 respectively, and the project was moved to the University of Tsukuba in 1981.
At the university of Tsukuba, PAX-128, PAX-64J, QCDPAX, and CP-PACS were constructed. The latest machine CP-PACS was built in 1996, and was upgraded to have 2048 nodes.
