It's a variation on Clang, so calling it a new language seems overkill. It adds the OpenGL notion of uniform and varying variables, so that you can be explicit about SIMD without it being awkward (pragmas, compiler flags, prayers, assembly readings). I rewrote some OpenCL kernels for ISPC and it was a great experience. The resulting shared object could just be loaded and called from ctypes in Python, where OpenCL requires a lot of rituals.
