If you don't know C++ well, you might be surprised how fast C++ can be sometimes. This is especially true when code involved is small, because then inlining - which is what C++ is very good at - and templating, which makes excessive inlining possible in the first place - has the most effect.The following code compares C and C++ sorting:  #include <iostream>#include <algorithm>#include <vector>#include "stop_watch.inl" // see https://gist.github.com/2057981#ifndef COUNT#define COUNT 100000000#endifint compare_int(const void* p1, const void* ...

During last semester I was attending Multiprocessor Architectures course, given at Facultad de Informática where I study my Computer Science degree.As part of the assignments due to pass the course, we had to do several programs written in C to benchmark matrix multiplication by testing different techniques and technologies. First of all we had to do a secuential program in three different versions:A normal one where the result matrix is ordered by rows and the loops range the matrix by rows tooAn “inter” version where the result matrix is ordered by rows but the loops range the...
