I don't think it was ever abandoned. Had a reasonable size team on it for at least the last five years. Just very focused on HPC for most of that. I believe it's running nicely on Frontier. It looks like there have been some dead ends on the path, e.g. HSAIL doesn't seem to be a thing any more. Also looks like making it run on older generations of graphics cards was hard work which might be why the supported card list was mostly the instinct line.
