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.

To attend the training in person, please contact me via email at jasona@tacc.utexas.edu.

Wrangler Maintenance 7 November 2017

Posted by Matthew Edeker on Oct 23, 2017 9:27:42 AM

Wrangler will be unavailable from 7:30am to 5:30pm CST on Tuesday 7 November 2017 for system maintenance.

Wrangler has been returned to production and the queues are open. A substantial upgrade was done to Slurm scheduler. Unfortunately, this meant jobs placed in the queue prior to maintenance were lost. We will be contacting users directly to ask them to resubmit. Thank you for your patience.

Wrangler maintenance has taken longer than expected and does not currently have an ETA for completion. We apologize for any inconveniences.
