All:
After installing Lubuntu 13.10 (64-bit Mac) on my MacBook, I notice an
anomaly with respect to multi-processor usage.
I installed gnome-system-monitor (because I like the graph showing
internet throughput).
On using it on other systems, when it's on a multi-processor system, it
shows a CPU-usage graph-line for each available processor. But in this
case (even though it has two processors), there is only one CPU-usage
graph line.
When I checked the "System Tools"..."System Profiler and Benchmark"
tool, it showed that it is a dual core (2 processor) machine, and that
each processor has a speed of 2 gigahertz.
Yet when I later ran Qsynth on it (where it was configured to use
PulseAudio, rather than JACK), there were cut-outs in the sound,
suggesting that perhaps it is only using one processor.
So I am wondering if the Gnome System Monitor is actually correct in
showing only one processor?
If so, why does the System Profiler show that it is a dual-processor?
