Nils,
the V890 and all other US-III/IV machines except for the E10K/E25K
are Uniform Memory Access with respect to I/O, so it should not
matter which CPU/core you select.
This is because all memory is connected to on-CPU memory controllers
and the IO bridge chip (Schizo, pcisch) transacts on the

Hi,
I am trying to reduce context switches on a V890 with 16 cores by delegating one
core to interrupt handling (by setting all others to nointr using psradm).
Does the hardware design of this machine imply that (a) particular core(s) is
best suited for this task?
Thanks,
Nils
