Weber is Purdue's new specialty high performance computing cluster for data, applications, and research which are covered by export control regulations such as EAR, ITAR, or requiring compliance with the NIST SP 800-171. Weber was built through a partnership with HP and AMD in August 2019. Weber consists of HP compute nodes with two 10-core Intel Xeon-E5 "Haswell" processors (20 cores per node) and 64 GB of memory. All nodes have 56 Gbps EDR Infiniband interconnect.

Weber nodes run CentOS 7 and use SLURM as the batch system 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 Weber, 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
