    Phoronix: NVIDIA, Mentor Graphics May Harm GCC

    Yesterday there was news that OpenACC 2.0 parallel programming support was coming to GCC complete with GPU acceleration support for NVIDIA GPUs. While it was exciting on the surface, it appears that this work may be poisonous and could have a very tough time making it upstream...

    Here's the link to nvidia/PGI OpenACC compiler https://developer.nvidia.com/pgi-acc...nd-c-compilers

    Because they actually like open source?

    I do not work at or for or own stock in either nvidia, amd or intel.

    So where is ARM GPU documentation? As a reminder here is my original post:

    As far as I know ARM doesn't provide documentation for their GPUs. Imagination don't either. And Qualcomm don't.

    In fact, I guess only Intel and AMD have provided doc for their instruction set, so Michael's contact seems wrong about everyone publishing documentation...
    I added the highlight just in case you can't see it.

    As Nille just wrote all of this discussion has been around GPU and my message explicitly stated GPU.

    From the start we talk about GPU ISA end the Article write about GPU ISA.
