Blender 3.0 takes support for AMD GPUs to the next level
NVIDIA, Intel and AMD sit on the ISO C++ and ISO Fortran standard committees. They voted GPU support into the C++ 2017 and Fortran 2018 ISO standards. While NVIDIA implemented this YEARS ago, almost 5 years after these ISO standards were voted in, Intel and AMD have not even announced a plan for implementing GPU support for ISO standard languages on their GPUs.<p>Instead, Intel and AMD strategy is pushing applications to &quot;rewrite CUDA with HIP&#x2F;OneAPI&quot;, which are not real standards and are no more portable than CUDA. The people claiming that they are &quot;open&quot;, probably also think that OpenACC is an open standard, even though it mostly only runs on NVIDIA GPUs.<p>If you care about portable GPU code, unfortunately, NVIDIA is the only vendor that actually delivers.<p>You can take your standard conforming C++ code _today_, not a single line of CUDA, OpenMP, OpenACC, etc. and the nvidia compiler compiles it and runs it on GPUs and multi-core CPUs. You can also take your normal Python NumPy code and run it on NVIDIA GPUs &quot;as is&quot; without changes.<p>It doesn&#x27;t get any more portable than that.<p>I don&#x27;t understand how there are so many people in these threads that apparently care about portability happy about AMD and Intel rewriting open source applications in their proprietary vendor-specific technologies, instead of angry about them pushing their proprietary technologies, instead of implementing GPU support for ISO standard languages, just like NVIDIA does.
