Virtual School of Computational Science and Engineering Summer School

Posted: April 16, 2015

We are happy to inform that we will be again one of about ten sites nation wide that will be webcasting this year's Virtual School of Computational Science and Engineering Summer School classes. There will be two classes, one devoted to Performance Tuning, running from August 17-21, and the other to Scientific Visualization, running on August 24-25.

For more information and to register, please visit the following links:
Performance Tuning - https://portal.xsede.org/course-calendar/-/training-user/class/420/session/704
Science Visualization - https://portal.xsede.org/course-calendar/-/training-user/class/382/session/703

Also note that these classes are free and open to everyone, not just University affiliates.

These classes will take place at the INSCC Auditorium (Rm 110) from 9am to 3pm MDT.


Matlab updated to R2015a

Posted: April 11, 2015

We have updated Matlab on Linux desktops and clusters to R2015a. This is a relatively minor update so we don't expect many issue with the update. If you encounter problems or want to update your Windows or Mac desktop, please, open a ticket with CHPC.


Tangent cluster down

Posted: March 30, 2015

Tangent cluster is having problems with a network switch so it has been taken down while the switch is being looked at. We will update once it's back up.


Matlab seminars

Posted: March 24, 2015

We will welcome Mathworks engineers to give two seminars titled "Top Productivity Tools and Acceleration Techniques in MATLAB" on Wednesday, April 8, from 2pm to 5pm at INSCC Auditorium (Rm. 110).

For more information and to register, please go to https://go2.mathworks.com/matlab-seminars-at-university-of-utah-sem-na-70273.


R update on Linux machines

Posted: February 3, 2015

We have built a new distribution of R that takes advantage of multithreading when processing numerical arrays and made it the default R to use on CHPC's Linux systems including the clusters. The multithreaded build will run in parallel on a single compute node and standard R linear algebra benchmark achieves 5-10 speedup on kingspeak as compared to the single threaded build. To use multiple nodes, a distributed parallel package such as Rmpi or snow is still necessary.

We have installed external packages that have been built for the older versions but if there is an additional package you need, please, let us know.

For details how to use R at CHPC, see the documentation at
https://www.chpc.utah.edu/documentation/software/r-language.php


IDL update

Posted: January 23, 2015

We have updated the default IDL distribution to version 8.4. Please, let us know if you notice any problems with it.
Also, there are some users that use older version that is hardcoded to their environment. If you'd like to use the default (latest) version, either edit your shell init scripts or get in touch with us for help.


Jan 22: FastX server upgrade has been completed

Posted: January 22, 2015

The FastX server upgrade has been completed. Please remember to upgrade your FastX clients to the latest version (version 39), and if you have any problems send in a report to issues.

Registration:

https://www.eventbrite.com/e/supercomputing-in-plain-english-spring-2015-registration-14309649547

(You only need to register ONCE for the whole semester, not for every week.)

We already have over 250 registrations!

So far, the SiPE workshops have reached over 1500 people at 248 institutions, agencies, companies and organizations in 47 US states and territories and 10 other countries:

* 178 academic institutions; * 29 government agencies; * 26 private companies; * 15 not-for-profit organizations.

SiPE is targeted at an audience of not only computer scientists but especially scientists and engineers, including a mixture of undergraduates, graduate students, faculty and staff.

These workshops focus on fundamental issues of High Performance Computing (HPC) as they relate to Computational and Data-enabled Science & Engineering (CDS&E), including:

  • overview of HPC;
  • the storage hierarchy;
  • instruction-level parallelism;
  • high performance compilers;
  • shared memory parallelism (e.g., OpenMP);
  • distributed parallelism (e.g., MPI);
  • HPC application types and parallel paradigms;
  • multicore optimization;
  • high throughput computing;
  • accelerator computing (e.g., GPUs);
  • scientific and I/O libraries;
  • scientific visualization.

The key philosophy of the SiPE workshops is that an HPC-based code should be maintainable, extensible and, most especially, portable across platforms, and should be sufficiently flexible that it can adapt to, and adopt, emerging HPC paradigms.

Prerequisite:

1 semester of programming experience and/or coursework in any of Fortan, C, C++ or Java, recently


January 22 at 4pm -- FastX server upgrade

Posted: January 9, 2015

Duration: about an hour

On Thursday January 22 at 4pm we will be upgrading the server side of FastX on the cluster interactive nodes (includes the meteoXX and atmosXX nodes) and the frisco nodes. This process will not take long (about an hour), but there is a chance that existing FastX sessions will not be accessible after the upgrade so we strongly suggest that all FastX sessions are shut down before this time. If this is not possible, at a minimum users should save the results of any processes running within a FastX session.

After the server side upgrade all users will also have to upgrade their FastX clients.

The reason we are doing this upgrade at this time instead of waiting for the next downtime is that we have been notified that we can expect up to a 4-6X speed gain for remote visualization operations using this new server version (version 38) with the latest client version (version 39), based on information provided by the company which produces the FastX product. To see the other fixes and improvements included in the release as well visit the Starnet site .

As always, if you have any questions or concerns with these plans, please contact us.
