Since 1999, we maintain several beowulf computer clusters, which we call Boadicea (*Beowulf Oriented Architecture for Distributed, Intensive Computing in Engineering Applications*).

The current configuration is:

Periferic services

  • Router: Intel Core 2 Duo E4500 2.2GHz.
  • Monitoring: KVM Virtual Machine over Intel i7 920
  • Display node: Intel Xeon 2.80GHz 4GB

boadicea08:

  • 12 Dual Intel Dual-Core Xeon L5240 3.0GHz with 8 Gb RAM.
  • Communications: 24-port Gigabit switch.

boadicea09:

  • 30 Intel i7 with 6-16 Gb RAM.
  • Communications: 3x 48-port Gigabit switch.

storage:

  • 6TB Raid6 -> 4TB Useful
  • 12TB Raid5 ->10TB Useful
