Thread: more than 8 threads for lw9xxx?

  1. #1

    more than 8 threads for lw9xxx?

    hi with the nr imminent release of quadcore intel xeons and probably a simialar thing for amd lightwave 9's choice of upto 8 threads has now hit a wall....when we get quad cpu quadcore chips in 2007 with an avalaiable 16 cores how will lightwave 9 make use of them when it can only be selected with a maximum of 8 threads?...

    juts looking to future proof lw9x

    Good Question .

    But IIRC Core 2 Quadro (Kentsfield) is 4 cores and not 8 and I'm not sure will Hypethreading be enabled (to make it look like 8 CPUs) in those first CPUs (probably only at Extreme version) so it's still "safe" with 8 threads in LW .

    intel's keynote speach this week saif that their quad core xeon chips shold start to ship in nov 2006..and a macpro or a dell precision should be able to hold them no problemo as they are the same pin config so 8 core pc's are just a few weeks away...and i'll hazzard a guess that a motherboard that can hold 4 of these cpu's [16cores] is nr ready...that'll make 8 core's non selectable doesn't it with the current lightwave 9.0?

    also have a look here..intel's roadmap to 80 cores in 60months...

    okay so 80 core maybe a bit of a pipedream...but 8core is here now...and 16core either with 2x 8 core or 4 x 4core will be here in 2007...time for lightwave to keep up...just make that dropdown list add in 16 threads, 24threads and 32 threads to futue proof it for a couple of years...

    :agree:

    16,32 threads would be cool to see in 9.xx

    Why a drop down box, why not just autodetect the thread count?

  9. #9
    why a drop down list?...because that's what lightwave has right now...it just top's out at 8 threads...we'd like to see it top out higher to keep inline to where multicore pc's are heading in 2007

    Auto-detecting is fine as a default, but the user should still be able to override it and select the number of threads they want.

    On my Dual Processor PowerMac G5 I sometimes set it to one thread if I want to render in the background while doing other things. I'll also set it to eight threads since it often renders faster with eight threads even though I only have two CPUs... even with the new Perspective Camera...

    The main reason I would threads user specified is due to some plugs having crash issues with multiple threads. One would want to be able to change thread # for these instances.

    Also, a good idea would be an option added in the # thread pulldown to detect threads. SO you get the best of both worlds.

    And some plug-ins still are not multi-threaded, which means that an automated thread detector without user override would, in effect, kill these plugs.

    Intuition beat me to it!

    - I know.
    - A very nice psychotic man.
    - Thank you.

    LW9 already defaults the threads to the number of CPUs it detects when first launched, until the user changes it...

    I'd rather FIRST see modeler recognize multiple CPUs/GPU than having 16/32 Threads in layout . You always can start 2 layouts for rendering (workaround yes but it works) but you can't model in two modeleres at same time .

    Right now Dual core Woodcrest has no Hyperthreading anable... So the next generation will surely do the same.
