Not exactly irrelevent for multitheaded

If the job isn't multithreaded or doesn't scale well
Originally posted by Delgarde View PostSure, but that "so long as" you mention is a pretty big qualifier. If you have a task that's infinitely parallelizable and doesn't require much communication between instances, then a cluster is ideal. On the other hand, if you have a task that's mostly single-threaded or which requires tight interaction between threads, clusters *are* irrelevant, because they don't solve the problem.
I've sometimes thought I should disable all but one Bulldozer module in BIOS for normal websurfing, video playback, and gaming (0ad doesn't make effective use of multicore) to save power, then re-enable all cores when editing video. This would be to save power, but having to remember to go back into setup each time would be a pain. These procs are supposed to "park" unused cores, but I've never observed that in Linux and never tested Windows at all as I don't have or use it. I would like to find a way to force-park and unpark cores from the OS.

Love to see what DDR 4 does for this CPU!
I haven't even looked to see what availability is like with DDR 4 but it would be very interesting to see what DDR 4 can do for this platform. Obviously you would need a test suite that is very good at loading up all of the cores in this chip. The other problem is that I don't know if the initial supply of DDR 4 RAM is faste enough to make a difference.
However that is what Phoronix is all about, testing and verification.
