CHPC Presentation Series

NLP Services at CHPC
Date: November 5, 2009
Time: 1:00 - 2:00 p.m.
Location: INSCC Auditorium
Presented by: Sean Igo

This presentation is an overview of the equipment and software presently available at CHPC for Natural Language Processing (NLP). It will also cover related resources for general Artificial Intelligence use such as machine learning and data mining, and will include a brief descripton of CHPC's general resources and how to access them.


CHPC Presentation: Telematic Collaboration with the Access Grid, 10/29, 1 p.m., INSCC Auditorium

Posted: October 26, 2009

Date: October 29nd, 2009 **Corrected**
Time: 1:00 - 2:00 p.m.
Location: INSCC Auditorium
Presented by: Beth Miklavcic, Jimmy Miklavcic, Josh Bross and Colin McDermott

The development of the InterPlay performance series began in 1999 and was built upon the Access Grid infrastructure. It was followed by an emerging first public performance in 2003 and continues to date. It has created many unique challenges and at present, the challenges have matured and multiplied with each subsequent performance. This developmental process, the issues surmounted and those currently being addressed are discussed in this presentation. Beth and Jimmy Miklavcic will provide an overview of the InterPlay performances from 2003 to 2009 and a preview of the Cinematic Display Control Interface being developed by undergraduate researchers Josh Bross and Colin McDermott.


CHPC Downtime completed sucessfully about 7:15 p.m. (10/13/09) - cluster up and scheduling jobs

Posted: October 13, 2009

CHPC successfully completed the downtime today. The /scratch/mm space which had been deployed on the marchingmen cluster prior to retiring that system, has been re-deployed on tunnelarch as /scratch/ta and is available on the interactive and compute nodes of the tunnelarch cluster.

If you see any problems with your desktop, please reboot and see if the issue is resolved. If the problem persists, please let us know by sending email to issues@chpc.utah.edu


CHPC Major Downtime: Tuesday, October 13th, 2009 - ALL DAY

Posted: October 7, 2009

Duration: From 8:00 a.m. until evening, Tuesday October 13th, 2009

Systems Affected/Downtime Timelines:

  • All HPC Clusters
  • Intermittent outage of CHPC supported networks
  • All CHPC supported desktops mounting CHPCFS file systems.

Instructions to User:

  • Expect intermittent outages of the CHPC supported networks.
  • Desktops mounting the CHPCFS file systems plan for CHPCFS to be unavailable most of the day. Those with Windows and Mac desktops should be able to function, but will not have access to the CHPCFS file systems. CHPC recommends that you reboot your desktops after the downtime.
  • All HPC Clusters will be down most of the day.

During this downtime maintenance will be performed on the cooling system in the Komas datacenter, requiring all clusters housed in the data center to be down most of the day. CHPC will take advantage of this down time to do a number of additional tasks, including work on the network and file servers.

All file systems served from CHPCFS will be unavailable for a good part of the day. This includes HPC home directory space as well as departmental file systems supported by CHPC. We will work to get things online as soon as possible.


CHPC Presentation: Introduction to Programming with OpenMP, 10/08, 1 p.m., INSCC Auditorium

Posted: October 6, 2009

Date: Thursday, October 8th, 2009
Time: 1:00 - 2:00 p.m.
Location: INSCC Auditorium
Presented by: Martin Cuma

This talk introduces OpenMP, an increasingly popular and relatively simple shared memory parallel programming model. Two parallelizing schemes, parallel do loops and parallel sections, were detailed using examples. Various clauses that allow user to modify the parallel execution were also presented, including sharing and privatizing of the variables, scheduling, synchronization and mutual exclusion of the parallel tasks. Finally, few hints were given on removing loop dependencies in order to obtain effective parallelization.


CHPC Presentation: Introduction to Programming with MPI, 10/01, 1 p.m., INSCC Auditorium

Posted: September 29, 2009

Date: Thursday, October 1st, 2009
Time: 1:00 - 2:00 p.m.
Location: INSCC Auditorium
Presented by: Martin Cuma

This course discusses introductory and selected intermediate topics in MPI programming. We base this presentation on two simple examples and explain the MPI parallel development of them. The first example encompasses MPI initialization and simple point to point communication (which takes place between two processes). The second example includes introduction to collective communication calls (where all active processes are involved) and options for effective data communication strategies, such as derived data types and packing the data. Some ideas on more advanced MPI programming options are discussed in the end of the talk.


***REMINDER*** Updraft users: /scratch/general and /scratch/uintah will be scrubbed of all data at Noon on MONDAY 9/28/2009

Posted: September 15, 2009

***REMINDER***

In order to optimize performance on the /scratch/general and /scratch/uintah file systems (on the updraft cluster) CHPC will use the General DAT of updraft from Noon on September 28th until Noon on Monday, September 30th. ALL DATA FROM THESE FILESYSTEMS WILL BE SCRUBBED! Please make sure that any important results you may have in those spaces is copied elsewhere by Noon, Monday September 28th, 2009.
