Computer processors

Gurus, can you help explain how this works.

Is dual core or quad core better for Pro-E?

Is dual core or quad core better for Mechanica?



I have 6 GB of ram on Windows XP x64, do I have to configure the 3 gig
switch I hear people talking about for Pro or Mechanica to utilize?

If so, how do you configure the switch?



Thanks in advance for all your help and insight.

Mike,

Pro/E can't take advantage of multiple processors (except maybe in assy retrieval?), so dual or quad (or even single) doesn't matter. Processor speed is more important to Pro/E than number of cores. Given the choice between more cores and more speed, take more speed.

Mechanica, on the other hand, I believe can use multiple cores, I believe. I'm not a mechanica user, so I'm not certain.

If you're running 64 bit windows you don't need the 3 gig switch, in fact it probably isn't even available. I think you may need to be running 64 bit Pro/E to take advantage of the extra memory.

While Pro/E does not take advantage of multiple CPUs/Cores, the system as a whole can. You can run Pro/E on one core while the OS, Office and other apps use the other core(s).

The 64bit version of Pro/E is required to take advantage of the extra memory.

Does the x64 version of ProE WF5 M050 use the 64 bit imbedded browser also?

[fstrieffler]

Would multi-core processors still help? Even though Pro/E might not be able to use them directly, would they allow other things running on the machine to be shuffled off to another processor, thereby effectively giving Pro/E more resources?

Thanks.

Mike,

I am not a Computer Processor expert by any means.

As for the question about RAM. The 3 gig switch for Windows XP is only
related to the 32bit version of the OS. A 32bit OS can't see anything
larger than 3 GB of RAM. If you are running a 64bit OS, you don't need to
do anything in order for all the RAM to be visible and usable by the OS.
This however does not mean that a software application is optimized for
using that RAM or Multiple Processor Cores.

I believe that Wildfire 4 supported multiple processors for threading an
assembly but not sure how much support Pro/E has for multi-core setups
across the board. I am running Wildfire 5 on Windows 7 Professional
64-bit. We have 6GB or Ram on some systems and 12GB on others. We are
running Quad Core's but I could not tell you if Wildfire 5 is taking
advantage of them.

Pro/E supports multi-core, but I think it's only for specific operations.

I don't think you can find processors without multi-cores anymore. I can
only hope Pro/E or CREO Elements/Pro will support them across all
functions. I seriously don't think PTC will be using many resources on
CREO elements/pro anymore, so the real question will be if CREO 1.0 will
support multi-cores across all functions. It would be nice.

I do agree that your entire system will benefit from multi-core even if
Pro/E does not. If you run other apps outside of CREO elements/pro, you
will benefit from the additional processors and RAM.

I also think that with i7 chips, there is some internal "shenanigan" that allow things to run faster with multi-cores... Sorry if I got too technical... Nyuk! Nyuk! Nyuk! 😉

Thanks...

As I understand the 'shenanigans' with the i7 & i5 (but not the i3, I believe) is that it will allow 'overclocking' for short bursts. In other words, the processor runs at X speed most of the time, but it will go Y% faster for short bursts.
