GPU Vendor/Programming Model Compatibility Overview

There are three vendors of HPC-grade GPUs (NVIDIA, AMD, Intel), and many different programming models to use the devices for general computing. It's a zoo! This repository collects data about the state of support of the various combinations, for C/C++ and Fortran.

The initial collection was done for a presentation (v1.0), continued to a blog post (v1.2), and further extended to a proper paper (v2.0).
The current version in HTML for can be found at x-dev.pages.jsc.fz-juelich.de/models/.

I'm happy to accept contributions for extension/correction. Please add issues or file a pull request (note the MIT license).

Structure

The core of the work is the compat.yml file, the YAML-structured raw data. By scripts and templates, this data is converted to HTML or PDF (via LaTeX; an SVG version is created from the PDF as well).

Files:

• render_table.py: Read in definitions from compat.yml, massage data, and generate HTML and/or LaTeX code. Can be either printed to screen and/or written to file. See render_table.py -h
• compat.yml: All the raw data, in YAML. Starts with SVG code for status icons. Then come the status assessments in form of dictionaries. And finally, a list of descriptions of the assessments.
• templates/: Folder for all templates to be consumed by the Python script, containing Jinja2 template files generating the respective code from the raw data. While a lot of the content is similar, there are some distinct differences – like how the footnotes are handled, because LaTeX is typeset while HTML is static.
• output-fragments/: Folder for generated files from the templates, plus skeletons containing boilerplate code to augment the generated files. For HTML, this is not much beyond the CSS; but for LaTeX this also includes some important definitions; but I did not want to cascade it any further.
• Makefile: Generate all of these. Check out make html pdf svg.

Also, _gen-symbols/ exist, which is part of my exploration for all of this. I just might need it if I change the icons.

SC23 P3HPC Paper

The template table-template--descriptions.in.paper.tex is a heavily modified version of the standard TeX template extended to -- amongst others -- support references (from references.bib). render_table.py can also generate references in HTML output, but the implementation is very fragile; lets hope it doesn't break🤞.

A preprint of the paper can be found at arxiv.org/abs/2309.05445.
