With directive coding, you annotate code with compiler directives to take advantage of parallelism or accelerators. The two primary standards are OpenACC and OpenMP.   ... , including extra CPU cores, and build the code for the targeted accelerator? Turns out a couple of directives are available.

of a program. If the compiler understands the directives, it creates parallel code to fulfill them. Directives have proven to be a good approach to easy parallelization, so OpenACC borrowed this approach (see

-GPU requires re-writing code to use the GPU cores. Some new methods (OpenACC) could help with this issue, but the traditional MPI model is being stressed by the new hardware. Similar to the early days of Beowulf
