This wiki is intended for the users of the Stanford shared research computing resources.  E.g. the "cardinal" and "corn" and "barley" machines.

+
----
-
The machines are available for anyone with a SUNetID. Simply "ssh corn.stanford.edu" with your SUNetID credentials. The DNS name "corn.stanford.edu" actually goes to a load balancer and it will connect you to a particular corn machine (e.g. corn21) that has relatively low load.

FarmShare is Stanford’s community computing environment. It is primarily intended for use in coursework and unsponsored research (note that some software tools, like ANSYS, are only licensed for use on Farmshare for academic course use, not research); users participating in sponsored or departmental research should investigate the [https://sherlock.stanford.edu Sherlock] service or other, local alternatives, instead. FarmShare is ''not'' approved for use with [https://dataclass.stanford.edu high-risk] data, including protected health information and personally identifiable information, and is subject to University [[Policy | policies]] on acceptable use.
-
The "barley" machines are only accessible via a resource manager (currently Open Grid Engine). You can submit jobs from any corn.  You'll need to ssh to corn-image-new.stanford.edu and a directory on /mnt/glusterfs will be created for you on non-AFS storage. E-mail the barley-alpha mailing list for more info.

__NOTOC__
-
The "cardinal" machines are older and slower and smaller and intended for long-running processes (on the order of days) that are not resource intensive. E.g. mail/chat clients.  You could log in to a cardinal and run a screen/tmux session there to do things on other machines...

This FarmShare Documentation Is Not Current

This wiki describes a previous version of FarmShare.

Accurate documentation of the current system can be found at https://srcc.stanford.edu/farmshare


FarmShare is Stanford’s community computing environment. It is primarily intended for use in coursework and unsponsored research (note that some software tools, like ANSYS, are only licensed for use on Farmshare for academic course use, not research); users participating in sponsored or departmental research should investigate the Sherlock service or other, local alternatives, instead. FarmShare is not approved for use with high-risk data, including protected health information and personally identifiable information, and is subject to University policies on acceptable use.

For a description of the current environment, see FarmShare 2. More information can be found in the service documentation.

    SSDS Consulting

    The SSDS group supports statistical software, including R, Stata, and SAS. They are located in the Velma Denning Room in the Bing Wing of Green Library and hold office hours Monday–Thursday, 2–5 PM, starting in the second week of each quarter and ending the last week of classes. SRCC staff are present on the third Tuesday of each month, from 2–4 PM. SSDS office hours are not held during the Summer Quarter.

    Software

    A variety of useful software, including some popular commercial software, is provided as part of the FarmShare environment. If something is missing, or a particular application, library, or utility needs updating, please let us know. We try to accommodate reasonable requests but staff time is limited.
