Important Franklin Announcement |

NERSC is preparing to upgrade Franklin to a quad-core XT4 system
starting next Tuesday, July 15th.
The upgrade work will be carried out in multiple phases in order to have
minimal impact on your access to the system. The system will be divided
into two sections during the upgrade: a "production environment" that
you will have continued access to, with very brief periods of system
unavailability, and a "test environment" where the upgrade work is being
performed.
Each of the current 2.6 GHz dual-core chips will be swapped with a
quad-core chip containing four 2.3 GHz AMD Opteron processor cores. Each
compute node will also be upgraded to 8 GB memory, shared by all cores
within the node, keeping the same average 2 GB/core memory as we have
now.
For more details on the upgrade, including a detailed time line, please
