Ahh - found the issue... hahah
Just set my defocus node to full precision - now all cores rendering at
100% - awesome
Cheers Peter - mu Linux is working... thank fluff.

Hi Peter
I did try the simple defocus tip - but it doesn't use all the cores
at 100%
i get half of the cores being used ( 8 threads out of 16) - and out of
that half - only one of the threads is using a full 100% - the rest are
down at around 10% usage
Hi,
No it doesn't - on my 16 core Linux machine, Nuke 7 uses all my cores
completely with that test, but I've configured Nuke to use my
hyper-threading cores too - by default, Nuke uses only the physical
cores and ignores the hyperthreaded cores - which I'm guessing is why
you're seeing 8 out of 16 being used.
If you do that "x" in the DAG thing, and enter "[set threads 16]" for
the TCL command, that will tell Nuke to use all your threads, but to
some degree this might make things worse, it's very difficult to say,
as different scripts and footage have different uses-cases in terms of
the way they pull in and process footage.
But the bigger issue sounds like you're only getting one core being
used at 100% - I'm not quite sure what the other 7 are up to -
something sounds quite wrong there...
Peter
