multithreading

[AntoineG92]

Hello,
I would be very interested to know how the multithreading actually works in this program. I tried to tweak the num_thread variable in src/word2vec from 1 thread to 2 or 3 threads but I do not see any significant speed up of training time. Is there another way to do it ?

I am fairly novice to c and would be very grateful if someone could explain me how this works.

Thank you !
Antoine
