Re: about virtual processors

For a 2CPU system most of us recommend using only a single CPU VP. Based on this, set: MULTIPROCESSOR 1 NUMCPUVPS 1 SINGLE_CPU_VP 1 NOAGE 1 AFF_SPROC 0 AFF_NPROCS 0 This is because IDS does not take advantage of only two CPUs well due to the overhead of managing the additional VPs. With 4 or more CPUs most of us use, and recommend using, one less CPU VP than CPU. However, there is some hint that faster CPUs, ie >300MHZ MAY be able to provide enough horsepower to add more than one CPU VP per processor which would imply that 2 CPU VPs on your system MAY gain you something. I am experimenting with 30 CPU VPs on a 20 CPU Sun ES6000 w/ 360MHZ processors. YMMV so experiment. -- Art S. Kagel Any organism which has ceased to grow, has begun to die.
