Go up one level in this thread


I am using a dual p6/200 with NT 4 WS SP5. Depending on the task you are
running, NT seems to utilize SMP quite reasonably. For instance a single p6/200
runs Crafty's bench in version 16.15 with 102 kN/sec. On the dual system (with
the usual SMP overhead), it performs at 192 kN/sec. I would say that's pretty
good. (Much better than your proposed 25% gain!)

However when you are using 8, 16, or even more processors, NT 4 will not serve
you well (I think it only supports up to 4). But NT 5 (has now this ridiculous
name of Windows 2000 professional), will support more CPUs.

I do not know the performance of Be for multiple CPUs when running Crafty. But I
am sure that you will be able to compile Crafty with GNU 2.9x for Be and tell us
your results.

Some people claim that Crafty 16.15 runs faster on NT 4 WS SP5 when compiled
with VC++ 6.0 SP3 than with any other current compiler/OS combination for
Intel-based systems up to 4 CPUs (but with at least two CPUs). (For the moment,
forget 98 and 95 since these OS'es only support one CPU.)
