 HPCC maintains and regularly updates an extensive software stack. Including provisioning tools, resource management, file transfer clients, development tools, a variety of scientific libraries, a variety of compilers (e.g. gcc/g++, OneAPI) and communication libraries (e.g., OpenMPI). Primarily provided by OpenHPC (https://openhpc.community/). Many opensource applications are custom compiled (about 100 or so used by many academic disciplines). The HPCC website offers documentation to help users resolve technical issues they may encounter (https://dokuwiki.wesleyan.edu/doku.php?id=cluster:0). Additional technical support (and tutors) is provided by the Scientific Computing and Informatics Center (https://www.wesleyan.edu/scic/) and the Quantitative Analysis Center (https://www.wesleyan.edu/qac/).
-ITS funds the system administrative support (0.75 FTE) of one ITS employee. Power and cooling are funded and maintained by Physical Plant. On an annual basis Academic Affairs contributes $25K and the HPCC users contribute $15K. This sets up a 4 year refresh cycle of $160K. On an annual basis Finance contributes up to $10K for maintenance (failed disks etc, monies do not roll over, use it loose it).

 All HPCC hardware is located inside Wesleyan's ITS data center. Physical access is limited by swipe cards to certain ITS personnel. All head/login nodes (2 to 4 or so) are located on an internal subnet protected by Wesleyan's enterprise wide firewall. VPN is required from off campus. The internal HPCC network consists of two private subnets for the 100 or so compute nodes (one for job scheduler and monitoring tools, one for data transfers and NFS mounts). Access to HPCC resources is based on local Linux accounts and groups.
