Hammer

Overview of Hammer

Hammer is optimized for Purdue's communities utilizing loosely-coupled, high-throughput computing. Hammer was initially built through a partnership with HP and Intel in April 2015. Hammer was expanded again in late 2016. Hammer will be expanded annually, with each year's purchase of nodes to remain in production for 5 years from their initial purchase.

To purchase access to Hammer today, go to the 2015 Cluster Access Purchase page. Please subscribe to our Community Cluster Program Mailing List to stay informed on the latest purchasing developments or contact us via email at rcac-cluster-purchase@lists.purdue.edu if you have any questions.

Detailed Hardware Specification

Hammer consists of several groups of hardware as the cluster is expanded annually.

Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Interconnect
Hammer-A 198 Two 10-Core Intel Xeon E5-2660 v3 20 64 GB 10 Gbps Ethernet
Hammer-B 40 Two Hyper-Threaded 10-Core Intel Xeon E5-2660 v3 40 (Logical) 128 GB 25 Gbps Ethernet

Hammer 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, optimized for jobs 8 cores or smaller and for maximum job throughput. 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 Hammer, ITaP recommends the following set of compiler, math library, and message-passing library for parallel code:

  • Intel 16.0.1.150
  • MKL
  • Intel MPI

To load the recommended set:

$ module load devel

To verify what you loaded:

$ module list
