Yes, I'm using the sarek target w/ solaris 10.

There exists only phys_mem0 object. What do I need to
do to have phys_mem1? Perhaps private L1 cache and
shared L2 cache? I would like to see memory accesses
from each processor.

No, I haven't. The current CPU switch time is 1000000
cycles.

How do I enable cpu1? Isn't it done automatically when
I set g_NUM_PROCESSORS to 2?

Thank you for your help.
