Hasta La Motion!

I have recently attempted to obtain some benchmarks for Nuke rendering on Linux systems. One thing I have noticed is that sometimes when rendering a scene with threads set to say 4 it may not render at all or rather it just looks like it hangs. I would have to decrease the number of threads for it to respond. I’ve even witnessed a few instances where my only option was to set threads equal to 1 for it to actually render. I am working with a (2 cpus / 12 cores) Fedora 14 system which also has hyperthreading enabled. Just wondered if anyone has any experience with using Nuke on Linux systems and perhaps share your experience with why opening up too many threads (which I should be able to) can cause rendering to hang.

Thanks.
