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.

Most Hammer nodes consist of identical hardware. All Hammer nodes have variable numbers of processor cores, and 10 Gbps or 25 Gbps Ethernet interconnects.
|Front-Ends||Number of Nodes||Processors per Node||Cores per Node||Memory per Node||Retires in|
|2||Two Haswell CPUs @ 2.60GHz||20||64 GB||2020|
|Sub-Cluster||Number of Nodes||Processors per Node||Cores per Node||Memory per Node||Retires in|
|A||198||Two Haswell CPUs @ 2.60GHz||20||64 GB||2020|
|B||40||Two Haswell CPUs @ 2.60GHz||40 (Logical)||128 GB||2021|
|C||27||Two Sky Lake CPUs @ 2.60GHz||48 (Logical)||192 GB||2022|
|D||18||Two Sky Lake CPUs @ 2.60GHz||48 (Logical)||192 GB||2023|
|E||15||Two Intel Xeon Gold CPUs @ 2.60GHz||48 (Logical)||96 GB||2024|
Hammer nodes run CentOS 7 and use Slurm (Simple Linux Utility for Resource Management) as the batch scheduler 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 Hammer, ITaP recommends the following set of compiler and math libraries.
- Intel 220.127.116.11
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
