Thanks. If I understood it correctly: * GCC 5 supports code generation for Xeon Phi (Knights Landing, KNL) * KNL (the hardware) is not yet available [mid 2015?] * liboffloadmic supports offloading in an emulation mode (executed on the host) but does not (yet) support offloading to KNL; i.e. one would need an updated version of it, once one gets hold of the actual hardware. * The current hardware (Xeon Phi Knights Corner, KNC) is and will not be supported by GCC. * Details for building GCC for offloading and running code on an accelerator is at https://gcc.gnu.org/wiki/Offloading Question: Is the latter up to date - and the item above correct? BTW: you could update gcc.gnu.org ->news and gcc.gnu.org/gcc-5/changes.html Otherwise: * OpenACC support is about to be merged (as alternative to OpenMP 4) * Support for offloading to NVidia GPUs via PTX is also about to be merged.
