Without access to GPU, the OpenACC code runs about twice faster comparing to the * OpenMP one, using the Nvidia HPC SDK <code>nvc</code> compiler. According to other data sources, with access to GPU, the CPU: 1x* OpenACC version should run about 7 times faster than the OpenMP solution that runs on CPU; and the Basic: ~1x* OpenACC version runs about 2Proper: ~4.5 times faster than an 5x* OpenMP version with GPU offloadingBasic: ~0.1x* OpenMP GPU Proper: ~4x
