Support for GCC and clang will appear in future versions of Grid when the AVX512 support within GCC and clang will be more advanced. - For BG/Q only [bgclang](http://trac.alcf.anl.gov/projects/llvm-bgq) is supported. We do not presently plan to support more compilers for this platform. - BG/Q performances are currently rather poor. This is being investigated for future versions. +- The vector size for the `GEN` target can be specified with the `configure` script option `--enable-gen-simd-width`. ### Build setup for Intel Knights Landing platform
