The Turing cluster was purchased with funds from the ITS FY2017 Budget in May of 2017. Much like the Biomath cluster, it is optimized for highly parallel jobs requiring very fast Infiniband networking between nodes. Anyone at Colgate is allowed to use the Turing cluster; please send an email to ITSHelp to get an account.
Turing consists of 20 nodes, a master (scheduler) node and a storage node. All are connected via a FDR Infiniband fabric network.
The job scheduler software, PBS Pro, handles the submission and running of intertactive and non-interactive jobs on the cluster.
The master and all compute nodes are directly attached to a FDR Infiniband Fabric. The fabric support transport speeds of about 54 Gbit/s and 0.7 microseconds of latency. The Infiniband fabric is configured to support IPoIB, which allows us to use standard TCP/IP programs and code on the Infiniband network. This makes writing code to run on the fabric very easy, with minimal overhead in the protocol.
The storage node and the infiniband switch both support EDR Infiniband, which has speeds of 96 Gbit/s and a latency of 0.5 microseconds.
A separate 1 Gbit/s Ethernet network is used for general maintenance only.
The master node and storage node are both directly connected to the Colgate campus network via standard ethernet.

Storage is housed on a Dell PowerEdge R730. The CPU is a Xeon E5-2623 v3 (3.0GHz) with 128GB of RAM. The storage array is composed of sixteen 1.2 TB (10,000 RPM) SAS hard drives in a ZFS Raid-Z2 configuration. This is similar to a RAID-6 configuration, but with the additional features of the ZFS file system.
Files stored on the Turing cluster can be accessed via ssh, sftp and scp. User home directories on Turing can also be connected to via samba from a Mac, PC or Linux workstation.

Please see Network Drives on Turing Cluster for more information about using samba.
The /home partition on storage.cluster is snapshotted daily at midnight. These snapshots exist for 2 weeks.
The /shared partition on storage.cluster is snapshotted weekly, on Sunday at midnight.
These snapshots are visible via /home/.zfs/snapshot/GMT-(date)/. Simple command line unix tools can be used to copy files to recover them to a writable location.
