Are all of these physical cores? All Soothsayer said is correct, but what is suspicious to me, is that cores are occupied exactly by half, which looks like hyper-thread issue… doesn't it? I haven't heard about such things under Windows though, old Linux kernels used to had this problem.
not all the cores is physical.
but mantra only use one cpu.
for example:
CPU1 is core 0~7 CPU2 is core 8~15
mantra always use core 0~7 and core 8~15 is not used.
or mantra will use core 8~15
i have a mac pro .i will try mac houdini to test this issue.
thanks reply.

There are bottlenecks in the rendering process.
The most scalable way to render is to use raytrace, it'll almost always use all cores 100%. That's very fortunate when you render volumes as they raytrace very fast.
If you are using micropolygon then I find that setting the render tile size makes a big difference.
thanks for your reply
I've try to set the tile size up to 64.Its still use half.
anyother way to use micropolygon with full cpu useage?
