### PGI

[PGI compilers](https://www.pgroup.com/products/index.htm)
deliver the performance you need on CPUs, with OpenACC and CUDA
Fortran for HPC applications development on GPU-accelerated systems. OpenACC and
CUDA programs can run several times faster on a single Tesla V100 GPU compared
to all the cores of a dual-socket server, and interoperate with MPI and OpenMP
to deliver the full power of today’s multi-GPU servers.
### NVIDIA

The [NVIDIA HPC SDK](https://developer.nvidia.com/hpc-sdk) C, C++, and Fortran compilers, former [PGI compilers](https://www.pgroup.com/products/index.htm), support GPU acceleration of HPC modeling and simulation applications with standard C++ and Fortran, OpenACC® directives, and CUDA®. GPU-accelerated math libraries maximize performance on common HPC algorithms, and optimized communications libraries enable standards-based multi-GPU and scalable systems programming.

A comprehensive list of available compilers is provided [here]({{site.baseurl}}/compilers). In this guide, we will focus only on those that are free to install and use.

Of those listed at the link above, open source and free are GFortran (with OpenCoarrays), Flang, and LFortran. Finally, NVFortran and IFort* are commercial with free community editions.
Of those listed at the link above, open source and free are GFortran (with OpenCoarrays), Flang, and LFortran. NVIDIA and INTEL offer their compilers for free and as of the latest update of this tutorial, NVFortran (NVIDIA) is available only for Linux systems, while Intel oneAPI is available for Linux, Windows and macOS systems. Both are well documented and readers can find detailed information about installing and using them on their websites respectively.

I think INTEL should be spelled as Intel.

Sorry, @certik I agree, but was too busy at work and missed the opportunity to correct things in time.

No worries @smeskos. Do you have time to submit a PR fixing this?


_Note_: *IFort (Intel's Fortran Compiler) does not offer a free community edition in general. However, if you are a student, educator, or open-source contributor, you may [qualify for free software](https://software.intel.com/content/www/us/en/develop/articles/qualify-for-free-software.html).

Both NVFortran (NVIDIA) and IFort (Intel) are well documented and readers can find detailed information about installing and using them on their websites respectively. In the next chapter, we use GFortran for the tutorial as it is a mature open source compiler. We encourage users to also try other open source and commercial compilers.
