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).

Detailed Hardware Specification

Radon consists of one logical 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. 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). Nodes contain 4 physical cores, but Hyper-Threading allows each core to process two execution threads, and jobs can request up to 8 cores from the scheduler.

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

  • Intel
  • MKL
  • Intel MPI

To load the recommended set:

$ module load devel

To verify what you loaded:

$ module list
