Overview of Bell
Bell is a Community Cluster optimized for communities running traditional, tightly-coupled science and engineering applications. Bell is being built through a partnership with Dell and AMD over the summer of 2020. Bell consists of Dell compute nodes with two 64-core AMD Epyc 7662 "Rome" processors (128 cores per node) and 256 GB of memory. All nodes have 100 Gbps HDR Infiniband interconnect and a 6-year warranty.
New with Bell is that access is being offered on the basis of each 64-core Rome processor, or a half-node share. To purchase access to Bell today, go to the 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 firstname.lastname@example.org if you have any questions.
Bell is named in honor of Clara Bell Sessions, minority advocate and Professor and Director of Continuing Education of Nursing. More information about her life and impact on Purdue is available in an ITaP Biography of Bell.
All Bell nodes have 128 processor cores, 256 GB of RAM, and 100 Gbps Infiniband interconnects.

Bell 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 Bell, ITaP recommends the following set of compiler and message-passing library for parallel code:
- GCC 6.3.0
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
