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.
