| By early December, we expect a single-cabinet test system ("Phase 0") to be delivered
| | #redirect [[Blue Waters Project]] |
| to NCSA, and plan to allow participating science team members access to it during the Fall
| |
| PRAC Workshop (Dec. 13). This system will have 52 XE6 compute nodes (832 AMD Interlagos
| |
| "Bulldozer" cores) and 32 XK6 compute nodes (256 Interlagos cores plus 32 Fermi accelerators),
| |
| all in the same interconnect fabric.
| |
| | |
| Early next year, a substantial (>1.3 PFLOP peak) system ("Phase 1") will be delivered to NCSA for early science
| |
| runs and possibly some porting and tuning. This system will be available for a few months, after
| |
| which it will be integrated with the rest of the cabinets comprising the full Blue Waters system.
| |
| By early January, we will send out detailed information on the process for getting access to
| |
| the early science system.
| |
| | |
| The table below summarizes the key parameters of the various Phases of the
| |
| Blue Waters system. Phase 2 is expected to go into production in Summer 2012,
| |
| and in Fall 2012, the Phase 3 system will have Kepler accelerators installed in the
| |
| XK nodes. For more details, see the newly revised Blue Waters PRAC wiki page:
