Parallelising your code. Do you do it?   [Edit]

Survey period: 5 Jul 2010 to 12 Jul 2010

Our CPUs aren't getting as fast as fast as they used to, and we're now well and truly in a multi-core world. What do you do to take advantage of this? (Suggested by El Corazon)

Most of the regulars know me. I solve big problems, use big machines, but mostly I draw pretty pictures for people. (hey, when push comes to shove, that is all I really do!) Yes, I am also the local parallel pusher (just had my parallel fix an hour ago too). If it is parallel, I use it, when not occupying my time fighting others in our company who don't. Smile | :) Our biggest machine is a dual-quad with dual GPU's -- in single threaded world that system is 500MFlop, in parallel and using everything inside to its advantage it is a 3TFlop calculating monster. The first supercomputer I worked on only did 380MFlop with 500 cores....

I use everything at my disposal, and I could have still checked the last item.... One of our programmers was soooo against threading that we mutexed the code into lockstep. I am still removing the damage. Admittedly I have a special case, reproducing the world we see around us cannot be done single threaded. Still I see so many people overlook areas where things can be threaded because performance doesn't matter (which is absolutely fine, as long as it is really true) and there is no need to do one thing while doing another (also fine, as long as it is true).

I hate our customers to wait. If my customer is waiting for something for even long enough to sneeze, I've got to find a faster way. Smile | :)
