Nettet2. mai 2024 · OpenACC Implementation. Very quickly we realized that the serial version of our code had many backwards compatibility issues and we had to rewrite the code for our grayscale, enlarge, shrink, and sobel edge detection functions to be parallelizable by openACC. This led to a speedup of slightly below 5x. Nettet3. jul. 2012 · mpicc is just a wrapper around certain set of compilers. Most implementations have their mpicc wrappers understand a special option like -showme (Open MPI) or -show (Open MPI, MPICH and derivates) that gives the full list of options that the wrapper passes on to the backend compiler.
