CONTRIBUTIONS are WELCOME!
* -m in a file name stands for multi-threading or multi-processing
* -i in a file name stands for direct intrinsics usage. (Usage of simd intrinsics via libraries is not counted)
* -ffi in a file name stands for non-stdlib FFI usage
* (You may find time < time(user) + time(sys) for some non-parallelized programs, the overhead is from GC or JIT compiler, which are allowed to take advantage of multi-cores as that's more close to real-world scenarios.)
