PathScale - a well-known provider of one of the industry's highest-performance 64-bit C, C++, and Fortran compilers - has added support for ARM and C++11 in their EKOPath 5 compiler suite. “We are pleased to provide the ARM HPC ecosystem with our new EKOPath compiler,” said Christopher Bergstrom, the PathScale Chief Technology Officer. “Our C/Fortran compiler and BLAS … [Read more...]
IPMACC – An Open Source OpenACC to CUDA/OpenCL Translator
IPMACC is a research-grade open-source framework for translating OpenACC source code to CUDA or OpenCL. Binary executables can then be created with OpenCL or CUDA compilers. The authors (Ahmad Lashgar - University of Victoria, Alireza Majidi - Texas A&M University, Amirali Baniasadi - University of Victoria) verified correctness and performance using benchmarks from … [Read more...]

The call closes Monday January 12, 2015. Poster Criteria The purpose of your poster is to convey to a wide audience a research project's significance to scholars in the field and its … [Read more...]
MultiOS Gaming, Media, and OpenCL Using XenGT Virtual Machines On Shared Intel GPUs
At last, a full (opensource!) GPU virtualization solution that allows virtualized guest operating systems to "own" a shared Intel GPU yet allows applications to run with near-native performance! This means games, both DRM and free media, plus OpenCL applications can run in separate guest operating systems on a single Intel GPU system (convenient for users) or in a shared cloud … [Read more...]
AMD and Pathscale Join OpenACC Standards Committee
AMD and Pathscale announced at SC14 that they have joined the OpenACC standards committee. OpenACC provides an efficient and performance-portable path for developing massively parallel programs across a wide range of accelerators, including GPUs, many core coprocessors and multi-core CPUs. OpenACC has been gaining traction for parallel programming. Such a move appears … [Read more...]
CreativeC GPU And Intel Xeon Phi Cluster For SC14 Class Runs Mobile In Van
Our all-day class at SC14 on Sunday November 16, “From ‘Hello World’ to Exascale Using x86, GPUs and Intel Xeon Phi Coprocessors” (tut106s1) received more than double our expected enrollment! Students will be able to run on both Intel Xeon Phi and GPU supercomputers at TACC via an Xsede allocation (thank you very much) and on a CreativeC supercomputer and visualization cluster … [Read more...]
Analysis of Phylogenetic Tree Code Shows OpenACC Within 10% Of Native CUDA
The paper, "Accelerating Phylogenetic Inference on GPUs: an OpenACC and CUDA comparison" by University of Barcelona and Intel Barcelona Research Center claim near-CUDA performance for OpenACC - within 10% - that can be achieved when accelerating a Phylogenetic Tree code based on the popular MrBayes Markov chain Monte Carlo (MCMC) package. Comparing with state-of-art … [Read more...]
MSI WS60 Mobile Workstation – Awesome CUDA-Capable, Linux, and Window Mobility
The recently released MSI mobile workstation (WS60 20 OJ 3K-004US) provides a no-compromise laptop for those who wish a thin-and-light desktop replacement at work and when traveling. This device is now my work machine of choice (that relegated a wonderful HP Z800 workstation to a remotely accessed resource). I have found that the WS60 provides a well-designed and … [Read more...]

The workshop is a fill-day event on October 20th, 2014, with a preceding welcome reception on October 19th, 2014. THis workshop is organized by the HPC Tools group in the … [Read more...]
OpenACC Compilers Deliver 85% The Performance Of Hand-Optimized Code
Directive-based compilers offer both portability and the ability to optimized code for specific platforms such as GPUs and CPUs. A recent LCPC14 paper, "Directive-Based Compilers for GPUs", by Swapnil Ghike, Ruben Gran, Maria J. Garzaran, David Padua at the University of Illinois at Urbana-Champaign found OpenACC code generated by the PGI and Cray OpenACC compilers achieved … [Read more...]
