Overview of Radon

Radon is a compute cluster operated by ITaP for general campus use. Radon consists of 45 HP Moonshot compute nodes with 32 GB RAM and are connected by 10 Gigabit Ethernet (10GigE).

Radon Detailed Hardware Specification

Radon consists of one sub-cluster "E". The nodes have 2.5 GHz quad-core, Hyper-Threading enabled Intel Xeon E3-1284 CPUs (8 logical cores), 32 GB RAM, and 10 Gigabit Ethernet.

Radon nodes run Red Hat Enterprise Linux 6 (RHEL6) and use Moab Workload Manager 8 and TORQUE Resource Manager 5 as the portable batch system (PBS) for resource and job management. 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 16.0.1.150
  • MKL
  • Intel MPI

This compiler and these libraries are loaded by default. To load the recommended set again:

$ module load rcac

To verify what you loaded:

$ module list
