February 29, 2008: Stop operation of the current system March 1, 2008: Start operation of the new system
DOWNGRADE? � � � Due to a serious restructuring of the budget in NAOJ, our computer system will be drastically downsized and functions for observation and data archive are prioritized. Great cut of computer budget for NAOJ as well as for Subaru. But, computation performance of each workstation (ows, ana…) will be upgraded.
