• the E cluster based on the CESDIS Beowulf Mass Storage System, now consists of:
  • 64 Dual Pentium Pro PCs (128 processors)
  • a 72-port Foundry Networks fast ethernet switch
  • 8 Gbytes of RAM
  • 1.2 TBytes of Disk
• the G cluster based commercial Gateway 2000 PCs consists of:
  • 16 Dual Pentium III Xeon fileserver PCs (32 processors)
  • attached to a 72-port Foundry Networks fast ethernet switch and Myrinet
  • 8 Gbytes of RAM
  • 72 GBytes of Disk
• the DL cluster based commercial Dell PCs consists of:
  • 10 Quad Pentium III Xeon fileserver PCs (40 processors)
