These node each have four RTX1080S (32 GB memory footprint) gpus providing 702 teraflops (mixed mode).

| All queues are available for job submissions via all login nodes. Some nodes on Infiniband switches for parallel computational jobs (queues: me256fd, 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 528 GB gpu side, 8,532 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 ''sharptail'' (our file server) from a direct attached disk array. In total, 10 TB of /home 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 /home are provided via disk-to-disk point-in-time snapshots from node ''sharptail'' to node ''cottontail'' disk arrays. (daily, weekly, monthly snapshots are mounted read only on ''cottontail'' for self-serve content retrievals). 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). In addition no-quota, no-backup user directories can be requested in /homeextra1 (7 T) or /homeextra2 (5 T). All home directories will migrate to a FreeNAS/ZFS appliance named ''hpcstore'' in 2020 (190T usable, scalable to 1.2P). | Home directory file system are provided (via NFS or IPoIB) by the node ''hpcstore'' (our file server) from a direct attached disk array.

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). |

| 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. | Two (old) Rstore storage servers each provide about 104 TB of usable backup space which is not mounted on the compute nodes.
