8-January-2014 - SU-HPC seminar: OpenMP 4.0
OpenMP 4.0, Michael Klemm, Intel
Thursday, January 23, 3:30 - 5pm, Spilker 232
Abstract: OpenMP 4.0 is the current release of the OpenMP API specification. It added new major features to the OpenMP language to incorporate latest technological trends in HPC and beyond. The new features will significantly increase the expressiveness of OpenMP and its applicability for complex HPC codes. In this presentation, we will provide an in-depth overview of the new features. The presented features include user-defined reductions, support for SIMD instructions, support for accelerators/coprocessors, and affinity.
Bio: Michael Klemm is part of Intel's Software and Services Group, Developer Relations Division. His focus is on High Performance and Throughput Computing.

Michael's areas of interest include compiler construction, design of programming languages, parallel programming, and performance analysis and tuning. Michael is Intel representative in the OpenMP Language Committee and leads the efforts to develop error handling features for OpenMP.
20-December-2013 - TotalView
The Computing Division is currently paying more than $2.5K for software maintenance and support for the TotalView product. The license allows 256 concurrent users, however, according to our logs, we are using much less than that number. We would like to understand the actual demand for TotalView by our community so that we can explore options, such as decreasing our license count.
Please let us know how critical this software is for your research, how often you use it, and what the impact would be if it were not available.
In January 2014, we will contact current TotalView users to gather information for planning and budgeting purposes.
