Introduction to Parallel Programming with OpenACC - Part 5

The fifth in a series of short videos to introduce you to parallel programming with OpenACC and the PGI compilers, using C++ or Fortran. You will learn by example how to build a simple example program, how to add OpenACC directives, and to rebuild the program for parallel execution on a multicore system. To get the most out of this video, you should download the example programs and follow along on your workstation.

Fortran version:
!$acc data copyin(A(1:nsize, 1:nsize), b(1:nsize)) copy(x1(1:nsize), x2(1:nsize))
do while(residual > TOLERANCE .and. iters < max_iters)

end do
!$acc end data
