 This page will be maintained and provide information to get users started using the compute cluster. It is a merger of the old "brief description" page and the "queue description" page.
+==== In General ====
+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 or 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.

-All queues are available for job submissions via cottontail2 login node. Some nodes on Infiniband switches for parallel computational jobs (queues: mw256fd, hp12, mw256).  Our total job slot count is roughly 2,624 with our physical core count 1,312. Our total teraflops compute capacity is about 58 cpu side and 2,462 gpu side (mixed mode). Our total memory footprint is about 1,200 GB gpu side,  13,012 GB cpu side.

-Home directory file system are provided (via NFS or IPoIB) by the node M40ha (our file server) from a direct attached disk array. In total, 500 TB of /zfshomes disk space is accessible to the users. Node ''greentail52'' makes available 55 TB of scratch space at /sanscratch via NFS.  In addition all nodes provide local scratch space at /localscratch (excludes queue tinymem). The scheduler automatically makes directories in both these scratch areas for each job (named after JOBPID). Backup services for /zfshomes are provided via disk-to-disk replication from node ''hpcstore'' to node ''sharptail'' disk arrays. The TrueNAs/ZFS appliance performs daily snapshots with a retention window of 180 days. Some faculty&students have their home directories on node ''ringtail'' which provides 33 TB via /home33. Some faculty&students have their home directories on node ''ringtail2'' which provides 66 TB via /home33. Some faculty&students also have their own storage (2x 110 TB via /mindstore).  Static content should be migrated to the Rstore platform.
