Port Some CUDA Codes To Intel Xeon Phi Simply and Efficiently

May 15, 2015 by Rob Farber Leave a Comment

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...]

GCC 5.1 Now Available – Includes Preliminary OpenACC and OpenMP 4.0

April 26, 2015 by Rob Farber Leave a Comment

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...]
