Overview of Halstead

Halstead is the newest of Purdue's Community Clusters, optimized for Purdue's communities running traditional, tightly-coupled science and engineering applications. Halstead was built through a partnership with HP and Intel in November 2016. Halstead consists of HP compute nodes with two 10-core Intel Xeon-E5 processors (20 cores per node) and 128 GB of memory. All nodes have 100 Gbps EDR Infiniband interconnect and a 5-year warranty.

Halstead is named in honor of Maurice H. Halstead, Professor of Computer Science and Software Science pioneer. More information about his life and impact on Purdue is available in an ITaP Biography of Maurice H. Halstead.

Detailed Hardware Specification

All Halstead nodes consist of identical hardware. All Halstead nodes have 20 processor cores, 128 GB of RAM, and 100 Gbps Infiniband interconnects.

Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Interconnect TeraFLOPS
Halstead-A 408 Two 10-Core Intel Xeon-E5 20 128 GB 100 Gbps EDR Infiniband 237.58

Halstead 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).

For more information about the TORQUE Resource Manager:

On Halstead, 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
