Ruby SSH key fingerprints

These are the public key fingerprints for Ruby:
ruby: = 01:21:16:c4:cd:43:d3:87:6d:fe:da:d1:ab:20:ba:4a
ruby: = eb:83:d9:ca:88:ba:e1:70:c9:a2:12:4b:61:ce:02:72
ruby: = ef:4c:f6:cd:83:88:d1:ad:13:50:f2:af:90:33:e9:70

These are the SHA256 hashes:​
ruby: = SHA256:685FBToLX5PCXfUoCkDrxosNg7w6L08lDTVsjLiyLQU
ruby: = SHA256:D7HjrL4rsYDGagmihFRqy284kAcscqhthYdzT4w0aUo
ruby: = SHA256:XplFCsSu7+RDFC6V/1DGt+XXfBjDLk78DNP0crf341U


An outage of Globus service is scheduled from 11 a.m. to 3 p.m. Saturday, December 9, 2017 for scheduled upgrades from Globus. Active file transfers will be suspended during this time and they will resume when the Globus service is restored. Users trying to access the service at will see a maintenance page until the service is restored.

DOWNTIME 7AM-7PM 12/12/2017

** DOWNTIME EXTENDED TO 7 PM ** A downtime for all HPC systems is scheduled from 7 a.m. to 7 p.m. Tuesday, December 12, 2017. The downtime will affect the Oakley, Ruby and Owens Clusters, web portals, and HPC file servers. Login services, including, and access to storage will not be available during this time. To stay up to date on system notices, follow @HPCNotices on Twitter ( As always, you can contact us at OSC Help.


Singularity is a container system designed for use on High Performance Computing (HPC) systems. It allows users to run both Docker and Singularity containers.

From the Docker website: "A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings."


We will have rolling reboots of Oakley and Ruby clusters starting from 8:30AM on Monday October 9, 2017. A rolling reboot of Owens will be scheduled for a later date. These rolling reboots will address recent security vulnerabilities patched by RedHat. These rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. We apologize for any inconvenience this may cause you. Please contact if you have any questions.


LAPACK (Linear Algebra PACKage) provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.

Availability and Restrictions

A highly optimized implementation of LAPACK is available on all OSC clusters as part of the Intel Math Kernel Library (MKL). We recommend that you use MKL rather than building LAPACK for yourself. MKL is available to all OSC users.
