Hello world with OpenACC

Compile and run a simple OpenACC test program, provided as hello(.c|.F90).

In order to compile the program on Puhti, you'll need to first load the following modules:

module load pgi/19.7 cuda/10.1.168

After this, you can compile the program using the PGI compiler (pgcc or pgf90). Just remember to turn on support for OpenACC (-acc flag with PGI).

An example batch job script (job.sh) is provided and can be used to run the program after fixing it with a valid account (project number).
