Are you primarily a user of OpenACC, or also interested in helping implement it in GCC? > I'm very interested to OpenACC support in GCC, I know that there is a > branch that contains a basic implementation for it. There's the openacc-1_0-branch, which Samsung had been using to implement OpenACC 1.0 with GIMPLE -> OpenCL translation, and there's the gomp-4_0-branch where several stakeholders are now implementing offloading (as libgomp plugins; used for both OpenACC and OpenMP's target construct), OpenACC, and the missing bits of OpenMP 4 (which has been the branch's original purpose). > How can I build gcc with this branch? Check out the branch, and build it; just like trunk or a release. > What is the actual status of openacc implementation? "Work in progress". :-) Not yet suitable for real-world code. > With a similar interest, I would like to merging support to OpenMP 4.0 > "target" directives, I know that actually only host is used as fallback... That's correct. The offloading code will be merged into trunk once its "ready" -- difficult to be more precise, right now. Grüße, Thomas
