We're certainly hoping that OpenACC & OpenMP 4 & Cilk+ can share certain parts of their implementations. We're already seeing OpenMP 4 and Cilk starting to converge on some stuff.Evgeny Gavrin wrote:What do you think about support of OpenACC 1.0 (http://www.openacc-standard.org/) in gcc?I like the idea - though, I wonder whether OpenMP 4.0's "target"* would be the better choice as it looks a bit more flexible and better defined. (Conceptually, they are very similar; I think the middle-end/back-end/library part would even be the same.)
In a perfect world, there'd only be one standard for this stuff. That's not likely, so I'd be happy with parsing/FE kinds of things being specific to each standard with everything from initial gimple generation through the optimizers being shared. That may not ultimately be possible, but I think that's the right way to look at the work.
