LoneStar5 has been returned to production and the queues and login nodes are available for use. We apologize for the inconvenience of having extended the maintenance window. We experienced hardware problems with Cray cabinet controllers as well as hardware issues with the /scratch shared filesystem. So please note that there will be performance degradation on /scratch until raid arrays are rebuilt over the next few hours. If possible please limit your IO on /scratch.

Texas Advanced Computing Center
ACB 1.104
J.J. Pickle Research Campus
10100 Burnet Rd. Austin, TX 78758

OpenMP is one of the most popular paradigms to exploit the now ubiquitous manycore and multi-core processors. In this beginner-level training session, we will provide an overview of the basic concepts of OpenMP. We will introduce the trainees to the Interactive Parallelization Tool (IPT) that is designed for parallelizing serial C/C++ programs semi-automatically. The participants in the training session will be introduced to OpenMP and will learn to use IPT for parallelizing their C/C++ applications.

Prerequisites: Experience working in a Linux environment, and familiarity with C/C++/Fortran or any other programming language.

We are offering the training to both in-person and webcast participants. Local participants are strongly encouraged to attend in person.

We are presently testing a resolution to the problems occurring between the external network (e.g. internet, license servers), and LS5 compute nodes. Please let us know if any further issues transpire. Thank you very much for your patience during this extended maintenance period.  

Updated on Aug 1, 2017 8:07:50 PM

LS5 has been returned to production. We apologize for the delay. Unfortunately the rsip service error was not resolvable within a reasonable time-frame and so the rsip errors persist. This means that some compute nodes are still unable to access outside IP addresses. We are able to make some changes towards resolving this while the system is running so please watch user news for updates to this service

Updated on Aug 1, 2017 5:08:32 PM

LS5 is still experiencing issues relating to the rsip server setup. We estimate that this can be solved within a reasonable amount of time and so are extending the LS5 until 23:00.

Do you have a computational problem that would benefit from using a large scale computing system?

Do you need to scale your simulation or data analysis to a petascale system?

Registration is now open for the “Scaling to Petascale Institute” to be held June 26-30, 2017. Details are at https://bluewaters.ncsa.illinois.edu/petascale-summer-institute

This institute is for people developing, modifying and supporting research projects who seek to enhance their knowledge and skills to scale software to petascale and emerging extreme scale computing systems. Participants should have familiarity with Linux, programming in Fortran, C, C++, Python or similar language, and familiarity with MPI (message passing interface). There will be hands-on activities for many of the sessions.

Presentations will be made by faculty and professionals from Argonne Leadership Computing Facility (ALCF), the Blue Waters project at the National Center for Supercomputing Applications (NCSA), National Energy Research Scientific Computing Center (NERSC), Oak Ridge Leadership Computing Facility (OLCF), Stony Brook University, and the Texas Advanced Computing Center (TACC).

The agenda will address the following topics.

MPI - Introduction and Advanced topics
OpenMP
Scaling, code profiling, and debugging
GPU programming
OpenACC
Phi programming

On April 28th, 2017; TACC will be offering a morning introductory course and an afternoon performance optimization course on OpenMP.

The morning course will introduce participants to the OpenMP threading model, and describe the basic constructs necessary to parallelize loops on manycore architectures. Topics covered will include understanding the fork/join threading model, using OpenMP pragmas, and loop parallelization.

The afternoon course will provide an introduction to OpenMP optimization techniques for manycore and vectorized architectures. Topics covered will include using OpenMP’s SIMD directives, configuring OpenMP thread affinity, and changing OpenMP thread scheduling behavior.

You are welcome to register for either or both courses. Both of the courses are available to in-person and webcast participants. Local participants are strongly encouraged to attend in person.

J.J. Pickle Research Campus
10100 Burnet Rd. Austin, TX 78758

This training will provide existing R users with training on how to use R in an HPC environment. We will cover logistical issues with getting your R code up and running on TACC resources, as well as how to take advantage of the unique resources available at TACC. This includes covering usage of the 'parallel' package in R and how to manage CRAN packages in a multi-user environment. Previous familiarity with R is assumed.

We are offering the training to both in-person and webcast participants. Local participants are strongly encouraged to attend in person.
