Hi Li,
number one, do:
cat /proc/cpuinfo
you should see both cpu's listed.
secondly to test the "real-world" effect.. start up a couple of cpu
intensive programmes, one should run mainly on one cpu, the other mainly
on the other cpu.
For a single process to take advantage of SMP it must be written with
threads, ie concurrent paths through the code.
eg try comparing the speed of an OpenGL programme linked to a normal Mesa
OpenGL rendering library, against the same OpenGL programme linked against
Mesa compiled with threads..
regards,
