Web5 de mar. de 2024 · I am interested in offloading work to the GPU with OpenMP. The code below gives the correct value of sum on the CPU //g++ -O3 -Wall foo.cpp -fopenmp #pragma omp parallel for reduction (+:sum) for (int i = 0 ; i < 2000000000; i++) sum += i%11; It also works on the GPU with OpenACC like this Web13 de fev. de 2024 · 1 I'm using OpenMP target offloading do offload some nested loops to the gpu. I'm using the nowait to tun it asynchronous. This makes it a task. With the same input values the result differs from the one when not offloading (e.g. cpu: sum=0.99, offloading sum=0.5). When removing the nowait clause it works just fine. WebThe Offload Modeling perspective introduces a new GPU-to-GPU performance model. With this model, you can analyze your Data Parallel C++ (DPC++), OpenMP* target, or OpenCL™ application running on a graphics processing unit (GPU) and model its performance on a different GPU platform.
