Many thanks, I'll read your link with attention. Do you have further links on threads and IPC ? I'm thinking in rewriting an old and unfinished logical interpreter in C that used assembly code (nasm) for truth evaluation of the smallest elements. I'd like also to create a "small" database for prime numbers (using John Moyer's storage code) in order to test several things on prime numbers distribution.
