HPC Cluster Page Updated with Julia Example Script

  • Wed, 11/02/2016 - 10:39am - Posted by: Mike Cammilleri

    We've added a simple example of submitting a Julia job to the SLURM cluster along with some important notes regarding Julia package directories and setting the appropriate environment variables. Be sure to check for updates to the HPC cluster info page here

High Performance Cluster now online using SLURM

  • Wed, 10/05/2016 - 11:02am - Posted by: Mike Cammilleri

    All,

    Statistics is now running our own high performance compute cluster consisting of six - many core, high memory nodes. The cluster will eventually replace the bigmemXX servers and the open, un-restricted way of running R, MATLAB, and other jobs. BigmemXX servers will be considered deprecated and will no longer be monitored for efficiency (if there was any).

    The new HPC cluster is considered in BETA as we continue to test and adjust the configuration. The system uses a job scheduler called SLURM (http://slurm.schedmd.com/) which is much like Condor in that it uses simple submit scripts to start and run jobs. The scheduler will allocate the requested resources and queue your jobs so that it will run well with other users.

Help Docs Only Available From Stat Machines

  • Mon, 01/04/2016 - 11:03am - Posted by: Mike Cammilleri

    Currently our Statlab Help Docs are only available from department computer terminals. This is due to some security issues to the wiki. We are currently moving the documentation into the main website. Thank you for your patience.

Network connectivity sporadic

  • Mon, 02/02/2015 - 1:37pm - Posted by: Mike Cammilleri

    We are experiencing some network issues that cause desktop computers to be unable to boot within the department. This is a campus level network issue and there is some delay in getting it resolved. If your computer can not boot either use a machine in the lab or contact us. Thanks for your patience.

How to perform long running jobs

    In order to maintain network permissions over time (days, weeks, etc.) you will need to take extra steps before executing your code. Here is an example of the commands to run using bigmem03:


    ssh bigmem03.stat.wisc.edu
    stashticket
    screen
    ssh bigmem03

    Ctrl-A d
    exit

    Then, reattach to your screen session by logging back into the server and typing

    screen -r

    If you need to know more about screen, see the man page for screen (man screen). The idea is to run an ssh session inside a screen session. This will ensure that your AFS tokens remain valid after you leave the computer for hours, days, or weeks at a time.

    TIP: you can... read more

Antivirus and other software

  • Wed, 09/03/2014 - 2:21pm - Posted by: Mike Cammilleri

    If you are bringing in your own laptop into the department, I strongly advise installing FREE anti-virus software available to you from campus. Norton Anti-Virus from the Department of Information Technology (DoIT) is a stripped-down, no advertising, no bloat/spy/mal-ware version of Antivirus that will not interfere with your computer. To download, use your campus NetID and password.

    Also, while you are a valid student, faculty, or staff of the UW System, you can get some discounts on other software such as Microsoft Office. Please do not use pirated software from other countries as we will not be able to support them... read more
