Overview of Brown

Brown is Purdue's newest Community Cluster and is optimized for communities running traditional, tightly-coupled science and engineering applications. Brown built through a partnership with Dell and Intel in October 2017. Brown consists of Dell compute nodes with two 12-core Intel Xeon Gold "Sky Lake" processors (24 cores per node) and 96 GB of memory. All nodes have 100 Gbps EDR Infiniband interconnect and a 5-year warranty.

Brown Namesake

Brown is named in honor of Herbert C. Brown, Nobel Laureate and Professor of Chemistry. More information about his life and impact on Purdue is available in an ITaP Biography of Brown.

Brown Specifications

All Brown nodes have 24 processor cores, 96 GB of RAM, and 100 Gbps Infiniband interconnects.
Front-Ends Number of Nodes Processors per Node Cores per Node Memory per Node Retires in
No GPU 1 Two Sky Lake CPUs @ 2.60GHz 24 96 GB 2022
Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Retires in
A 550 Two Sky Lake CPUs @ 2.60GHz 24 96 GB 2022

Brown nodes run CentOS 7 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 Brown, ITaP recommends the following set of compiler, math library, and message-passing library for parallel code:

  • Intel
  • 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
