is there any way to simulate a slow cpu?

Question

i have a piece of coursework that that involves running a program on minix 3
which i am running on vmware.
i have to play around with the cpu allocation algorithms

the problem is my core i7 is way to fast so is there any way to simulate hardware like a pentium 1 or restrict the am mount of clock that virtual machine can have, or any other software
regards
mitch

Answer 1

Normally you can specify the processor speed and type along with available RAM that the virtual machine has in the configuration settings for that VM.



DR Bears face you are somewhat misinformed, 80286's predated the pentium processors by about 10 yrs. The first 80286 was released in 1982 and ran at 6Mhz and 8Mhz. They where followed by the 80386 in 1985 (running at 12Mhz) and then the 80486 in 1989 (running at 50Mhz). The first pentium's where released in 1993 and ran at 50 and 60Mhz. The name pentium was chossen over 80586 when Intel where told they could not copyright a number.

jointly as im particular it may be severe-high quality to have a swifter CPU, in case you dont choose one, you dont choose one. you besides mght easily do to no longer reformat or reinstall each time you have subjects. in case you're having to try this you have severe issues. you relatively could desire to in no way could desire to try this. A nicely maintained compute can run for an exceptionally long term with out ever having a difficulty, i know, mine does. the only element you suggested that jumps out is the CPU utilization being indexed at 80 5-a hundred%. In otherwords its working at finished load. Now, is it doing this once you dont have any apps working, or once you attempt to do artwork? If its the former, you merely approximately veritably have a virulent disease/secret agent ware/despite working. while idle the CPU, even slower ones, could desire to coach little or no utilization. Now if it DOES coach little or no utilization while idle, and then once you are attempting to run the apps you like, it runs at finished load(and slows down), thats an illustration that your desires have outgrown the CPU. if so, its time for an improve.

Answer 3

Hi

I should speak to grandad he could have one in the cupboard that would best show how lucky you are to have such a powerful tool to work with.

Pentium 1 what you really mean is a 286 then that would be approx 35mhz and if its got a maths coprocessor then that would by a 386dx not a 386sx some still worked at 25mhz and 1mb ram.

That would be 15 years old at best..

back in 1984 it was 12mhz so now you see how far we have come in 5 years.

Answer 4

Interesting question. You can change how much RAM your system uses in your bios. Or allocation of your graphics card memory, in bios too. That might be a good start.

Answer 5

You could may be clock it down by reducing your FSB down to something ridiculous... like 10mhz that's if your motherboard would let it... I've never personally tried it before, so I don't know if the BIOS will let you.

Answer 6

There are some Z80 simulators around would that work?

Answer 7

add up some ram!!
