Michael: I'm pretty sure you and I are on the same wavelength, but an alternative reading of your response is that I'm trying to isolate more than one cpu and your work doesn't support that yet. For others who may be reading this message thread casually, isolcpus=3 tells Linux to isolate cpu #3, not isolate 3 cpus. Since the kernel numbers the cpus from 0, isolcpus=3 for a quadcore machine and isolcpus=1 for a dualcore machine both say isolate the highest numbered cpu. For this and your subsequent two messages, thanks. I'm very impressed and pleased by the progress you've been making in the grand unification of different approaches to realtime processing. I'm confident that you and our other major contributors will conquer the niggly stuff (which I can follow only in broad outline; OS internals were never my cup of tea). I've got several more systems to play on while you look into RTAPI. By the way, "Heisenspike" is a great turn of phrase...made me laugh.
