[Simh] Reduce CPU usage

[Hittner, David T (IS)]

And what version of VMS are you running? Different versions of VMS have different idle characteristics..

Hi Priya,

This is one of those "it works for me" cases.  Idling works fine for a VMS guest on my fc18 x86 test system.

What is the output of "SHOW VERSION" done at the "sim>" prompt?
What does your configuration file look like?

Hi,

The cpu usage while running the emulator is shown as 97% to 99%. Is there a way to reduce this?
And I tried setting the cpu idle but no use. CPU utilization is still high.

sim> show cpu
CPU     idle disabled, model=VAXServer 3900 (KA655), NOAUTOBOOT
        64MB, HALT to console
sim> SET CPU IDLE=VMS
sim> show cpu
CPU     idle=VMS, idle enabled, model=VAXServer 3900 (KA655), NOAUTOBOOT
        64MB, HALT to console

Host OS used is Linux. fc18.

Thanks,
Priya
