Updated on Mar 29, 2016 1:48:37 PM

The course description has been revised to include an agenda and additional details for this event. Please review the following updated description.

The course will cover features that are becoming more important to HPC as shared-memory microarchitectures are becoming more complex, and the need for directing the parallel execution of even more complex coding paradigms is becoming paramount to achievement of efficient programming and optimal performance.

Three major topics will be explored to address these challenges.

1.)OpenMP Tasking basics:
Syntax and operation, synchronization, data-sharing model, dependencies and prioritization. Examples and lab will show how to generate tasks and control tasking for while loops, task loops, pointer chasing and tree searchers as well as show how to set up task dependences among tasks.

2.) OpenMP SIMD basics:
SIMD syntax and combination with parallel loop directives. SIMD directives are used to advise compilers about execution of loops within the SIMD execution units (vectorization). For instance, this includes use of linear variables, alignment of arrays and forced SIMD execution. Moreover, the declare SIMD directive provides mechanism for creating vectorized functions. Examples and lab will illustrate vectorization of loops and functions for optimally executing code in SIMD logical units.

3.) OpenMP Thread Affinity basics:
Declaration of places and bind operations. OpenMP now provides a general, non-vendor-specific syntax and runtime control to place threads of a work-sharing loop (and nested loops). The control can be directed to abstract places (cores, sockets, etc.) or numbered places (cpu ids). Also, binding policies describe mapping distributions. Examples and exercises will illustrate situations where affinity may be needed for testing and/or obtaining optimal thread binding.

After presentation topics labs will provide experience for using syntax and concepts, in simple-to-understand examples; and experiments on codes will test understanding. Late afternoons will be used for lab reviews and providing assistance with users who are interested in implementing new OpenMP features in their code. (The latter is limited to availability of the three instructors.) Additional OpenMP features (including proposed 5.0 features) may be discussed in the late afternoon if time permits.

Updated to include the date, and time of the course:

April 22nd, 2016
1:00pm - 5:00pm CT

The goal of this training workshop is to provide introduction and guidance on how to develop and run applications with Hadoop and Spark clusters. This course is being offered to in-person attendees on UT’s main campus in POB room 2.402 and to remote attendees via webcast. Due to support considerations, access to Wrangler for hands on exercises will be restricted to confirmed in-person attendees.

There are four sessions in this training workshop. In the first session we will give an introduction on the MapReduce programming model and how to develop Java applications with the MapReduce library to use on a Hadoop cluster. In the second session we will demonstrate how to run Hadoop applications, using the Hadoop Streaming interface to utilize other programming languages and other Hadoop based libraries. In the third session we will give an introduction on developing Spark applications with Java. And in the fourth session of the workshop we will will demonstrate different ways to utilize Spark clusters including running Spark applications using spark-shell and other packages.

This training will primarily use the Java programing language. The participants are advised to have prior knowledge and experiences with Java application development. During the training sessions, in-person participants will have opportunities to practice with prepared exercises and examples on Wrangler. In-person attendees who would like to participate in class exercises should also have basic knowledge on working with Wrangler or review our previous training sessions' materials on this topic at the following link before the workshop starts.

In consideration of our remote participants that are unable to attend in person, we have decided to offer a webcast session for this course. Please note that due to support constraints, participation in the hands on lab exercises will be reserved for in-person attendees.

This is an introductory course to give attendees an overview on the analytic software and environment support on Wrangler. In this course, we will cover software like R, Python, Hadoop and Spark. The goal of this course is to let users try out those support to decide if it is suitable for their research and prepare users to get started with Wrangler system. Advanced knowledge on those software packages and programming language is not required to attend this course. When considering whether or not to attend this course, please note that we plan on offering an in-depth course in April 2016 on Spark and Hadoop, and an in-depth course in May 2016 on Parallel R.  If you are interested in attending these upcoming courses, we strongly recommend attending Introduction to Data Analysis on Wrangler in order to be better prepared.

You are welcome to attend this course in-person on UT Austin's main campus in the POB building, room 2.402. Registration closes on March 2nd, 2016 at 12:00 PM.

Python is a commonly used language for scientific application development. To take full advantage of modern supercomputing resources or even modest HPC clusters with Python based applications it is crucial that the developer understand how to parallelize their code.

This class will cover the Python module, mpi4py, that provides a Message Passing Interface (MPI) implementation and enables multi-node computation. In addition, the multiprocessing module, which provides general multi-process computation, will be covered. Both topics will be illustrated through hands-on examples.

This course is intended for students that have proficiency with the Python language and with the Linux OS command-line. In order to participate in the lab exercises, students' machines must have ssh/terminal capability and have logged into TACC HPC systems.

The Texas Advanced Computing Center (TACC) is pleased to announce that Lonestar 5 (ls5.tacc.utexas.edu) is now in full production. This new system enables researchers across the state access to a 30,000 core, 1.2 PetaFlop Cray XC40 customized by TACC staff to provide a unique environment designed to meet the needs of our diverse community of computational researchers. Like Lonestar 4, Lonestar 5 will also include both GPU-enabled and large memory nodes.

Lonestar 5 has been funded by a collaboration between the University of Texas System, Texas A&M University, Texas Tech University, the Institute for Computational Engineering and Sciences and the Center for Space Research at UT Austin, and TACC.

Accounts of active Lonestar 4 users have automatically been activated on Lonestar 5. PIs with active Lonestar 4 allocation have allocation on Lonestar 5. The amount of Lonestar 5 allocation is .75 of the Lonestar 4 balance on Monday, January 11, 2016. Allocation expiration dates remain the same.

PIs without a current Lonestar 4 allocation should request Lonestar 5 allocation via the TACC User Portal.

https://portal.tacc.utexas.edu

The existing Lonestar 4 will remain in production through Monday, February 15, 2016 to enable users to migrate codes and data to the new system. Lonestar 4 login nodes will remain available through Monday, March 14, 2016 for access to $WORK and $SCRATCH for current Lonestar 4 users to further facilitate migration of their projects to Lonestar 5. Please note the following important dates:

  • January 11, 2016: Lonestar 5 production begins 
  • February 15, 2016: Last day of Lonestar 4 production 
  • March 14, 2016: Last day of access to Lonestar 4 login nodes, $SCRATCH, and $WORK

NOTE: Be sure to read the Lonestar 4 to Lonestar 5 transition guide, available at the following URL:
