Web2 de jul. de 2012 · If you have been following Parallel Forall, you are already familiar with OpenACC. OpenACC is an open standard that defines compiler directives for parallel computing on GPUs (see my previous posts on the subject ). We can add a single line to the above example to produce an OpenACC SAXPY in C. WebWhat is OpenACC? A set of directive-based extensions to C, C++ and Fortran that allow you to annotate regions of code and data for offloading from a CPU host to an attached …

Webor writing them to disk. For example, MPI has basic support for describing the layout of user-de ned data types and sending user-de ned objects between ranks [4]. A Fortran compiler could automatically perform deep copy, since Fortran pointers are self-describing dope vectors. In fact, deep copy is the language-speci ed behavior for intrinsic WebOpenACC defines an extensive list of pragmas (directives),[30]for example: #pragma acc parallel#pragma acc kernels Both are used to define parallel computation kernels to be executed on the accelerator, using distinct semantics[31][32] #pragma acc data Is the main directive to define and copy data to and from the accelerator. #pragma acc loop cst software logo
