Is there a setting in C4D or the SDK to set the number of CPUs? I would like to do multi-processor testing of my shader plugin on a single-CPU system. I know some other packages let you set the number of CPUs manually, but I didn't see anything like that in C4D.
Has anything changed from R7 to R8 for developers with respect to handling multithreading? I read in the R8 press release about it taking advantage of "several innovations in CPU technology (such as Hyperthreading)." I have someone using an R7 plugin with R8 on a dual and getting crashes.
Thanks,
Jane

Yes, go to Preferences->Common and set Render Threads to something else than Optimal. Now when you render C4D will used the specified number of threads (splitting the image in horizontal segments).

Also, notice that the other threads may take a while to start, so the effect is only visible on scenes that take more than a couple of seconds to render.
