HPSS Outage Tue Mar 19 - Fri Mar 22

March 12, 2013 by Francesca Verdier

The NERSC HPSS "User" system ( will be down for four days from Tue Mar 19 07:00 to Fri Mar 22 17:00).  The system will be upgraded from HPSS version 6.2 to version 7.3.

This new version of the HPSS server software is not compatible with current GridFTP servers.  This means the NERSC HPSS systems will not support any grid-based transfer methods (including GlobusOnline) following the upgrade.  We expect to install a fix for this problem during a scheduled downtime by the end of April.

All users now enabled on the new Cray XC30, Edison Phase I

All user accounts have been enabled on the first phase of Edison, NERSC’s newest HPC resource, a Cray XC30. The system was installed last December and is currently in the pre-production phase, a time when NERSC users are given access to the machine, and also when NERSC and Cray staff are still making improvements to the system. Users are invited to run jobs on the Edison Phase I system free of charge in exchange for providing feedback to NERSC staff about their experiences using Edison.
