| All queues are available for job submissions via all login nodes. Some nodes on Infiniband switches for parallel computational jobs (queues: mw256fd, hp12). Our total job slot count is roughly 2,144 with our physical core count 1,480. Our total teraflops compute capacity is about 58 cpu side, 25 gpu side (double precision floating point) and 702 gpu side (mixed mode). Our total memory footprint is about 560 GB gpu side, 8,916 GB cpu side. | All queues are available for job submissions via all login nodes.

| Home directory file system are provided (via NFS or IPoIB) by the node ''hpcstore'' (our file server) from a direct attached disk array. In total, 190 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 365 days. Some faculty have their home directories on node ''ringtail'' which provides 33 TB via /home33. Some faculty also have their own storage (2x 110 TB via /mindstore). All home directories will migrate to a FreeNAS/ZFS appliance named ''hpcstore'' in 2020 (190T usable, scalable to 1.2P, ETA summer 2020). | Home directory file system are provided (via NFS or IPoIB) by the node ''hpcstore'' (our file server) from a direct attached disk array.

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. |

| Two (old) Rstore storage servers each provide about 104 TB of usable backup space which is not mounted on the compute nodes. Each Rstore server's content is replicated to a dedicated passive standby server of same size, located in same data center but in different racks. As of Spring 2019 we have added two new Rstore servers of 220 T each, fully backed up with replication. Faculty may request shares for their labs to off load static content from the HPCC. | |

| Commercial software has their own queue limited by available licenses. There are no scheduler license resources, just queue jobs up in appropriate queue. Commercial software jobs are processed on the nodes of mw256fd and mw128. | There are no scheduler commercial software license resources. Only stata has a limited 6 user license. |

| **There are no wall time limits in our HPCC environment except for queue ''test''.** You are responsible for checkpointing though. Consult these pages, all nodes in all queues are DMTCP enabled (read [[cluster:190|DMTCP]]. Login nodes and storage nodes are on UPS but all compute nodes are on utility power. Crashes do happen, be prepared to restart your long running jobs. | **There are no wall time limits in our HPCC environment except for queue ''test''.** You are responsible for checkpointing though.
