APL (and it's descendants J and K) has everything needed to do justice to SIMD/GPGPU. And it had them since the early 60s. I am not aware of an APL compiler that actually uses GPU or SIMD instructions, but one is possible, and wouldn't require any change to the base language.

Not surprisingly, this is because the idiomatic model is closer to the SIMD mindset than to the "standard" (algol/pascal/c/java/python/go) mindset, which is why it is unlikely to ever become popular.
