The GRAPE Cluster
| ¡¡ | Master | 4 Slaves |
| CPU | 2 x Dual Core Zeon 5130 (2GHz) | 2 x Dual Core Zeon 5130 (2GHz) |
| Memory | 2 GB | 1 GB |
| Hard Disk | 500 GB | 80 GB |
| GRAPE | no GRAPE boards |
1 GRAPE6-BLX64 board each (260K particles, 130 Gflops peak) |
This cluster was installed and is being maintained by the Astrophysics group at Kyung Hee University. Four more GRAPE slaves will be added by May 2007.

History
Nov 2006 : The consortium was formed in a pork restaurant near Kyung Hee University to build up a cluster of GRAPE machines.
Jan 2007 : Ordered the first set of four GRAPE6-BLX64 boards and host computers.
Feb 2007 : First set arrived.
Mar 2007 : Installed the first set.
Apr 2007 : Ordered the second set of four GRAPE6-BLX64 boards and host computers.
