CPU utilization based on CPU count??

[jkdh33a]

I have noticed that on our machines that Solid Edge seems to limit itself on the CPU usage. I tried a Dell Precision dual PIII 1.13 MHz and a clone dual P4 Xeon with Hyperthreading enabled. Edge.exe would stop at 50% utilization on the PIII and 25% on the P4 (Hyperthreading makes the machine emulate 4 CPUs). Meanwhile SE works on the feature I'm trying to place and the system idle process sits at 60+% depending on what else is running.

I tried V11 and V16 and they both showed the same behavior. Has anyone else seen the same behavior?

We see the same behavior here on a dual Xeon. SE never uses more than 50% of both CPUs.

I think that's because SE is not optimized for multiple processors, therefore uses only one CPU. CPU usage shown is the average of both : 1 at 100% and one at 0%, so 50% usage.

Brou is correct. For solid edge, you are better off to not have hyperthreading turned on. Since hyperthreading essentially turns oen processor into two, and SE can only use 1 processor (not multithreaded), it will only use 1/2 of the physical processor (what hyperthreading would show as 1 full processor).

The hidden line display mode in Solid Edge supports multiple processors. If your computer contains multiple processors, hidden line performance is improved.

That's what I found in SE help.
