    After Effects not reporting virtual cores

    Visualart.be Level 1

      I'm currently installing my new workstation and came across the same issue however, I have 36 physical cores, 72 virtual cores but only 36 are visible by AE.

      Using latest CC2014.

          Relax.  It's not that important.  AE doesn't use virtual processors.

           

          As Mylenium pointed out in a previous thread, AE makes spotty use of the Render Multiple Frames Simultaneously feature, because not all effects can use it -- they only use one core.  If you have a lot of effects stacked on a layer, and only ONE of those effects is limited to a single processor, AE will use a single processor.

           

          If you wish to use multiprocessing if at all possible, an acceptable rule of thumb is to allocate 1/4 of your PHYSICAL processors  to the OS and other applications, and let AE have the others, with about 4 gigs memory assigned per processor.  If it's able to use multiprocessing, it will, but it's a crap shoot.

            ok, fair enough, brings me down to my next question, how can I assign more then 6gb (max selectable in dropdown) per process ? I got 256GB at hand.

            Most of the time I don't use all cores assigned to AE anyhow (cause it's plane silly to have like 35 instances of ae running on your system)

             

            About time AE gets some proper multithreading doh...

              Those values in the menu are under your control. You can change them in the preferences file. The line that defines the 6GB entry looks like this:

              "MP - Allocation Per Background Process v2 Preset VI" = "6.000000"

                Hi Todd, thanks for the feedback, managed to change it.

                 

                However onto next thing when I look at the resources AE is using it's far from using the potential of my new workstation.

                Are there specific things I should look at or change to get AE more up to speed ?

                 

                Current hardware setup:

                 

                2x Intel Xeon E5-2699v3 @2.30Ghz (2x18core)

                256GB Ram

                System disk: 2x120gb SSD RAID0

                Scratch disk: 2x120gb SSD RAID0

                Workdisk: 4x512GB SSD RAID0

                Video: 2x GTX980

                Windows 8.1 Pro

                 

                So for example, I'm loading in a 4K DNG sequence, I would expect Disk Usage would get up to maximum speed, however in Resource monitor it shows it's using only a mere 10MB/sec

                For this example CPU & RAM are behaving quite normal as I don't expect it to be CPU intensive or Fill up my RAM completely.
