Hello,

I think the original question was how to run a matrix to vector multiplication efficiently in parallel. 
The usage of C libraries is one way to handle it. However, we do not see the description of actual use-case.
At least, it was not clear to me… was the question about pure “math” multiplication or something else.

All-in-all Here is very good description how to run matrix to vert multiplication in parallel. I guess you can dap at the technique for your need.

So basically what you suggest is that I need an external piece of software written in a low level language that uses low level SIMD instructions on the bare CPU or maybe uses GPU. --2096565089-1804289383-1407247931=:5440
