Bolt

t story compares? https://github.com/HSA-Libraries/Bolt https://github.com/NVIDIA/thrust in the last few years they have (once again) dumped everything and started over, ROCm supported essentially no consumer cards and rotated support rapidly even in the CDNA world. It offers no binary compatibility support story, it has to be compiled for specific chips within a generation, not even just "RDNA3" but "Navi 31 specifically". Etc etc. And nobody with consumer cards could access it until like, six months ago, and that still is only on windows, consumer cards are not even supported on linux (!). That's fine for non-commercial and HPC, but it makes it difficult to imagine ever shipping commercial products to end-users on it. I guess you... ship as source, and your users have to figure out ROCm and compile it in-situ? Or ship a binary for every single GPU to ever release (including NVIDIA, Intel, ....) https://geohot.github.io/blog/jekyll/update/2023/06/07/a-div... This is on top of the actual problems that still remain, as geohot found out. Installing ROCm is a several-hour process that will involve debugging the platform just to get it to install, and then you will probably find that the actual code demos segfault when you run them. AMD's development processes are not really open, and actual development is silo'd inside the company with quarterly code dumps outside. The current code is not guaranteed to run on the actual driver itself, they do not test it even in the supported configurations, because all the development is happening on internal builds etc, not release code. oh and AMD themselves isn't using the open driver of course... they only test and validate on AMDGPU-PRO. it hasn't got traction because it's a low-quality product and nobody can even access it and run it anyway, let alone ship commercial products on it. and now everyone regrets it because it's turned into a money fountain.
