Send questions to ciser@cornell.edu
SCHEDULED DOWNTIMES: The Athena nodes are routinely taken down (usually every other month), for security and software updates and routine maintenance. During these periods all nodes and the CISER file server may be down for 24 hours or more. Please keep this in mind when planning long-running jobs. The next scheduled downtimes are:
- December 19, 2007: 6:00 AM - 3:00 PM (completed)
- February 27, 2008: 8:00 AM - 4:30 PM (completed)
- April 16, 2008: 8:00AM - 4:00 PM (completed)
5/08/2008 update: note time change below.
5/05/2008: Interrupted access to CISERRSCH servers
- All network connectivity in Rhodes Hall will be unavailable from 7 AM - 10 AM on Sunday, May 18, 2008. Jobs on the computing servers will continue to run, and will maintain read/write access to your home directory. But you will not be able to access any of these systems, or your CISER home directory, from your local computer during this time.
4/30/2008: New Server added to CISERRSCH
- Another new node has been added to the CISER Research Computing systems:
- RSCH101.ciserrsch.cornell.edu
- This new node has the same specifications as RSCH102-105.
4/16/2008 at 4:00 pm
- All of the CISER Research nodes (Athena 01-02, 64-65 and RSCH102-105) and the associated file server are back online!
- SAS is now on all of these nodes, including RSCH102-105!
- R has also been installed to all of the nodes (except Athena64-65)
- Stata, Adobe, SPSS, TextPad, and Atlas.ti have been updated, and EditPlus is now on all the nodes as well.
- For a more complete list of the software available on each node please see http://ciser.cornell.edu/athena/athena_software.shtml
As always, please report any problems to ciser@cornell.edu
4/16/2008 at 1:00 PM
- The following nodes are back up and available. Please use them as you would any other "Athena" node.
- RSCH102
- RSCH103
- RSCH104
- RSCH105
- SAS Users: please note that SAS is now installed on ALL of the nodes above!
3/26/2008:
- Athena101 was shut down this morning.
- It will not be brought back online in this domain.
- RSCH102 - RSCH105 rebooted this morning due to an interruption in power.
- These nodes should be back online soon.
- Any jobs you had running on any of these nodes will need to be restarted.
We are pleased to announce the installation of FOUR new compute nodes for your research!
The systems are named RSCH102, RSCH103, RSCH104 and RSCH105. Your access remains consistent with logging into the ATHENA nodes, we have just updated the naming convention. (ie: rsch102.ciserrsch.cornell.edu, rsch103.ciserrsch.cornell.edu, etc.)
Details of the nodes are as follows:
- OS: x64 bit Windows
- CPU: Four-Quad core (=16 CPUs)
- Memory: 128 Gigabytes
- T:\temp: over 400 Gigabytes
See http://www.ciser.cornell.edu/athena/athena_software.shtml for software available on these nodes.
2/27/2008
- DOWNTIME UPDATE:
- All Athena nodes (01, 02, 64, 65, and 101) are now back up.
2/20/2008
- Athena01 restarted unexpectedly today shortly after 2 PM. It is back up now. If you had jobs running there you will need to re-start them.
The CISER Research Nodes ("the Athena nodes") , and file server, will be down for maintenance and upgrades on
Wednesday, February 27th, from approximately 8 AM - NOON (EST,USA).
During this time you will have no access to:
- Athena01
- Athena02
- Athena64
- Athena65
- Athena99
- Athena101
- RSCHDFS file server (i.e. the U:\ drive where your home directory resides)
Please be sure to end your jobs and save files to your home directory before the downtime! We will post a notice to this page when the nodes are back up on Wed the 27th.
1/21/2008
- Athena15, 17, and 20 will be taken offline permanently on Monday morning, January 28th.
- If you have been in the habit of using those nodes please make sure any current jobs are ended before Monday morning, and that you have saved all of your output to your home directory, and not to the desktop or the C:\ drive of any node!
- If you need a refresher on proper file storage please see http://ciser.cornell.edu/athena/ciserrsch_sections/athena_c5.shtml#storing
- If you are a Mathematica, R, or S-Plus user please note that those 3 applications will be moved to Athena01 and Athena02.
- If you have been in the habit of using those nodes please make sure any current jobs are ended before Monday morning, and that you have saved all of your output to your home directory, and not to the desktop or the C:\ drive of any node!
- Please note: There are big and exciting changes in store for CISER's general research computing system, currently known as "the Athena nodes", beginning next week! These changes involve retiring Athena 15,17, and 20, to make room for four new 4-way, quad core, Dell Power Edge state-of-the-art servers which we expect to have in operation by mid-February! We will also be phasing in a name change from "the Athena nodes" to the "CISER Research nodes". We will be posting updates and new announcements to this website and to our Athena-l e-list.
