Nuredduna Mosix Hardware

Hardware Configuration

Nodes (computational units)

  • Nuredduna mosix cluster has currently 70 nodes and a grand total of 200 computational cores.

  • 40 nodes with Intel Core2 E6600 dual-core processors running at 2.4 Ghz on Intel DQ965GF and Asus P5B-VM microATX motherboards with Intel 965 chipsets

  • 30 nodes with Intel Core2 Q6700 quad-core processors running at 2.66 GHz on a Gigabyte GA-G33M-DS2R microATX motherboard with Intel G33 chipset

  • The amount of memory of each node ranges from 2 to 8 GB of DDR2 running at 667 MHz, for a total of about 280 GB of RAM

  • Nodes are diskless. That implies less power consumption, less heat generation, more reliability and less cost.

  • Nodes are boxed in slim form factor cases Aopen H360 with 300 W PFC power supply.


  • We use three 48-port Gigabit Ethernet switches. One HP Procurve 2448 and two D-Link DGS-1248T. Each of them have a switching capacity of 96Gbps.

  • Switches are connected among them through the IFISC Vlan on the campus network.

  • Node 1 is directly connected to the IFISC Vlan.

  • The other nodes are connected to one of the switches using the Gigabit Ethernet interface integrated on the motherboard.

  • The disk server Dolsa is also directly connected to the IFISC Vlan through two Ethernet cables in channel bonding configuration, providing higher speed and more reliability.

  • The whole cluster is located on floor 0 of the "Instituts Universitaris" building, in a room specially designed for it, including technical floor for cabling. We have a 40A triphasic electrical supply backed up by UPS and a power generator. The cooling capability is 20000 frigories
