The argument seems to be that C isn't suited to SIMD because some functions (exp, for instance) are not. But it then talks about how exp is implemented in hardware, in a way that forces it to be a non-SIMD calculation. That's not a C issue, that's a CPU issue. No language can save you there (unless it uses a software-only function for exp).
Is this article really confused, or did I misunderstand it?
The thing that makes C/C++ a good language for SIMD is how easily it lets you control memory alignment.
