The "Hadoop cluster" consists of 58 nodes with 464 physical cores in total, each node having:

  • 2 sockets Intel Xeon CPU E5520 @ 2.27GHz, 4 cores each, hyperthreading active (16 cores total)
  • 36 GB of RAM
  • 2 TB of disk
  • 1 GE network connection
  • OS Scientific Linux 5.5
    • Linux kernel 2.6.18

plus 2 headnodes, each having:

  • 2 sockets Intel Xeon CPU E5520 @ 2.27GHz, 4 cores each, hyperthreading active (16 cores total)
  • 96 GB of RAM
  • 10 GE network connection
  • OS Scientific Linux 5.5
    • Linux kernel 2.6.18

All nodes are however SHARED between the different Hadoop tasks and the OpenNebula virtual machines.
