The free upgrade for users of Windows 7 and 8.x has arrived! It will be rolled out starting with people on the Windows Insider program who participated in the evolution of the new "Windows-as-a-service" policy (jokingly referred to as the "eternal beta"). Apparently, Windows is now a "service", meaning that you will get to keep it free of charge for the lifetime of your machine … [Read more...]
More Trinity Racks Installed
"The proof of the pudding is in the tasting" is coming to fruition for the Trinity procurement as Cray installs more racks of the Trinity self-hosted Intel Knights Landing (KNL) processors. Each set of 12 cabinets is delivered, connected and tested one row at a time, by the Cray installation team. When all the phase-one cabinets have been delivered (60 in all), Cray will … [Read more...]
PathScale Supports OpenMP4 and OpenACC On NVIDIA, AMD, ARMv8, Plus Some CUDA
PathScale is capitalizing on over six years of development with the release of ENZO 2015, a compiler suite that allows C/C++/Fortran parallel programs to be built for a variety of hardware platforms from a single OpenACC or OpenMP4 source base. The PathScale compilers can generate executables for AMD GPUs, and NVIDIA GPUs as well as ARMv8 and x86 instruction sets. As a result, … [Read more...]
Intel Extends Barcelona Supercomputing Center
Intel extended it's research collaboration with the Barcelona Supercomputing Center (BSC) – one of four Intel exascale labs in Europe. Begun in 2011 and now extended to September 2017, the Intel-BSC work focuses on scalability issues as parallel applications move towards the exascale. BSC has been making HPC tools such as an instrumentation package (Extrae), a performance data … [Read more...]
Intel Xeon Phi Optimization Part 1 of 3: Multi-Threading and Parallel Reduction
This tutorial begins a 3-part series of educational publications on performance optimization in applications for Intel Xeon Phi coprocessors. In this publication, Ryo Asai (a Researcher at Colfax International) and Andrey Vladimirov (Head of HPC Research at Colfax International) will focus on some aspects of thread parallelism implementation in the OpenMP … [Read more...]
Aug. 2015 Computational Chemical Biology Conference in Australia
The Computational Chemical Biology conference is Chaired by Ross Walker (University of California San Diego) and Ian Gould (Imperial College London) will bring together scientists to discuss multidisciplinary research that leverages computer simulation to address key questions crossing the physical sciences-life sciences/biomedical interface. Topics will include advances in … [Read more...]
Port Some CUDA Codes To Intel Xeon Phi Simply and Efficiently
This tutorial shows that it relatively easy to port many CUDA C/C++ source codes to OpenMP. In the past, such efforts were not generally considered worthwhile because of the large performance difference between multicore processors (that use OpenMP) and GPUs. The introduction of teraflop/s Intel Xeon Phi coprocessors eliminated that performance difference, which makes it much … [Read more...]
No longer a preview – Intel updates the INDE OpenCL Code Analyzer
Intel has updated the new OpenCL™ Code Analyzer, a feature of Intel® INDE OpenCL™ Code Builder, which adds performance analysis capabilities integrated into a Microsoft Visual Studio OpenCL development environment. No longer a preview, the OpenCL Code Builder now supports OpenCL code development, which enables developers to carry on performance optimizations in each step of … [Read more...]
Microsoft Holographic Academy – Great comments, expensive Hololens device to launch with Win10
Previews of Microsoft Hololens show very positive comments and a wildly expensive pricing model with Forbes.com reports Microsoft Hololens will cost significantly more than $400. For that money, preview partners like cnet report, "[t]he experience still leaves me giddy, and ready to toss an as yet undisclosed sum of money into Microsoft's coffers", backed by ubergizo who wrote, … [Read more...]
GCC 5.1 Now Available – Includes Preliminary OpenACC and OpenMP 4.0
The GNU project has released GCC 5.1, which is a major update including a preliminary version of OpenACC and OpenMP 4.0 capability. The source code can be downloaded and built from the mirror sites or the SVN server. Don't expect much in terms of OpenACC performance as the execution model currently only allows for one gang, one worker, and a number of vectors. OpenMP 4 looks … [Read more...]
