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.
