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.

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.

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.
