I do (an aging Abit BP6 with dual Celeron 433s).
[james@howells proc]$ grep cpu stat
cpu 8638 486 3637 29070 4949 115 0
cpu0 8638 486 3637 29070 4949 115 0
[james@howells proc]$ grep processor cpuinfo
processor : 0
[james@howells proc]$ ls /sys/devices/system/cpu/
cpu0
At a quick glance, I can't see any way of spotting that this is a SMP
system.
However, SMP kernels should run perfectly well on single processor
systems: is there any chance, Chadley, that you can run your script
under a kernel compiled for SMP?
