I am new to OpenACC which is a new programming standard for GPU Acceleration as well as CPU. As per my knowledge OpenACC is a language which is a compiler directive, directly we can accelerate the ...

I study a lot of articles and the manual of OpenACC but still i don't understand the main difference of these two constructs.

I have been playing around with parallelization both using ACC and OpenMP in Fortran. I am now trying to do the same in matlab. I find it very interesting that it seems to be very hard to paraleliz...

I was wondering what are the major differences between openacc and openmp. What about MPI, cuda and opencl ? I understand the differences between openmp and mpi, especially the part about shared a...

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) fo...

I've been searching the web but I'm still very confused about this topic. Can anyone explain this more clearly? I come from an Aerospace Engineering background (not from a Computer Science one), so...

Are there any OpenAcc compilers that support the copying of derived types containing allocatable arrays to/from the GPU and their use in accelerated code? The OpenACC spec (v2.0) states this is p...

According to NVIDIA website: "The CUDA Toolkit complements and fully supports programming with OpenACC directives." Does this mean OpenACC programs (pargma and API) can be compiled with...

I am learning OpenACC (with PGI's compiler) and trying to optimize matrix multiplication example. The fastest implementation I came up so far is the following: void matrix_mul(float *restrict r, f...
