  6. NEW BOOK: OPENACC FOR PROGRAMMERS Edited by: By Sunita Chandrasekaran, Guido Juckeland Discover how OpenACC makes scalable parallel programming easier and more practical • Get productive with OpenACC code editors, compilers, debuggers, and performance analysis tools • Build your first real-world OpenACC programs • Overcome common performance, portability, and interoperability challenges • Efficiently distribute tasks across multiple processors • READ MORE

  7. RESOURCES Paper: From MPI to MPI+OpenACC: Conversion of a legacy FORTRAN PCG solver for the spherical Laplace equation “Overall, adding OpenACC to POT3D to add multi-GPU capabilities did not involve overly extensive development time, and for PC1 only required a 3% change in the source code. This, combined with the positive GPU performance results, encourages us to move forward in implementing OpenACC in our global MHD code MAS. The lessons learned in the POT3D implementation will be of great assistance in that venture, and we hope they will also be of assistance to other researchers considering adding accelerated computing to their legacy code using OpenACC.“ READ NOW
