Overview of Radon

Radon is a compute cluster operated by ITaP for general campus use. Radon consists of 24 64-bit, 8-core Dell 1950 systems with 16 GB RAM and 1 Gigabit Ethernet (1GigE) local to each node.

Detailed Hardware Specification

Radon consists of one logical sub-cluster "D". The nodes are 2.33 GHz quad-core Intel E5410 CPUs, 16 GB RAM, and 1 Gigabit Ethernet.

Radon nodes run Red Hat Enterprise Linux 5 (RHEL5) and use Moab Workload Manager 7 and TORQUE Resource Manager 4 as the portable batch system (PBS) for resource and job management. Radon also runs jobs for BoilerGrid whenever processor cores in it would otherwise be idle. The application of operating system patches occurs as security needs dictate. All nodes allow for unlimited stack usage, as well as unlimited core dump size (though disk space and server quotas may still be a limiting factor).

On Radon, ITaP recommends the following set of compiler, math library, and message-passing library for parallel code:

  • Intel
  • MKL
  • OpenMPI 1.6.3

To load the recommended set:

$ module load devel

To verify what you loaded:

$ module list
