Jakub Jelinek <jakub at redhat dot com> posted on July 16th that the GCC 4.9.1 release now supports OpenMP 4.0 in Fortran (as well as C/C++). This is great news for multi-core programmers. GCC looks to be on-track to become the opensource platform that both Intel Xeon Phi and GPU programmers can use to to test pragma based programming. As reported on techEnablement.com, … [Read more...]
GCC likely to support both OpenACC and Intel Xeon Phi Offload Pragmas in 2015
It looks like GCC will be supporting both OpenACC and Intel Xeon Phi offload pragmas in future releases. Perhaps the GNU compiler chain will become the melting pot where OpenACC and OpenMP 4.0 pragmas merge to become a single unified syntax. According to Nathan Sidwell, Director of Sourcery Services at Mentor Embedded, their OpenACC effort is working to “make the underlying … [Read more...]

Try Quantum Computing in Your WebGL-enabled Browser
GPUs are wonderful for running energy minimization algorithms where a system relaxes to a low energy state to solve a problem. The 13 PF/s Titan Deep-learning teaching code is a compelling example of this ability. Similarly, Quantum Computing solves a problem (like RSA encryption) by having a quantum system relax to a low energy state. Google has created a WebGL Chrome … [Read more...]
Pragma Puzzler – Ambiguous Loop Trip Count in OpenMP and OpenACC
Pragma-based programming can be described as a "negotiation" with the compiler where the compiler has to assume corner-cases that are not apparent to the programmer. So why does the loop count in the OpenMP and OpenACC article, "A First Transparent OpenACC C++ Class" have to be assigned to a separate variable to generate a parallel … [Read more...]
