Introduction to Parallel Programming with OpenACC - Part 2

The second 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.

I have one question, sir, you did not add any flags such as cpu or gpu which you use.

[Recordingization]

How to solve the problem if using openacc slower than sequential program?

[Recordingization]

Hello, Mr, may I know whether openacc can be used in GPU as well as in CPU?Should I add flags like -acc -gpu=cuda11.0 or -acc -ta=gpu?

please do this again with a syntax colored code editor. This is a lot harder to follow in monocolor.
