hmmm i've been playing a bit with threads. I'm running 3.3-RELEASE + SMP (dual pIII/450's) anyway... i didn't mess with installing the linux_threads port i noticed that there already is a pthread.h header file on my system i was looking at the Parallel Processing HOWTO from the LDP (linux documentation project) i compiled and ran their sample code for computing Pi (the linear version) and THEN i dl'd /compiled/ ran the pthread version of computing Pi by doing a gcc -pthread file.c it compiled right away and ran fine. comparing "time" between the two binaries, i got a 16% increase in speed using the pthread version versus the linear version. my question... what does all this mean as it relates to this thread? (no pun intended) i ran across something somewhere where the linux_threads port was outdated, or already included in the 3.x versions.. just curious as to what all this means, as the code source was from a Linux HOWTO. thanks!
