I haven't seen that talk, but from a previous one, Flang is closely related to the PGI compiler, and F18 is to escape that.
I wouldn't miss the grief associated with ifort, which doesn't live up to the mythology. The salient feature of the PGI compiler is probably the offloading, and I assume that's Nvidia-specific, but I don't know how it compares with current, and upcoming, GCC support. The research computing world would be a better place if the money spent on proprietary compilers sponsored GCC improvements instead.
- bondant 7y agoFrom what I've seen, PGI's offloading (with OpenACC) still delivers better performance than GCC, although GCC is improving. Also PGI usually give better error messages or comments about what it's doing when offloading. But yes offloading with PGI is for Nvidia cards only, and GCC contributors are working on adding support for offloading to AMD GPUs.
