more than 1 processor for CATIA
more than 1 processor for CATIA
(OP)
I have CATIA V5 R15. Will having two processors do any good with CATIA V5 R15? Is the software setup to accept multithreading?
What about hyperthreading? Does having hyperthreading enabled help when working in CATIA V5 R15?

RE: more than 1 processor for CATIA
I have recently acquired an Intellistation A Pro with 2.2 GHZ proc, and 4GB RAM. I have 2 of these machines, and will be running SMP once my second processor option board arrives. This will be a mirror of the first machine - 2X 2.2 GHz proc, 2X 4GB RAM, etc. Even if it's not double throughput, it will still be useful for running multiple session, or multiple intensive applications.
BTW - off topic, but does the second processor need its own graphics adaptor?

The rest as far as I am aware in uniprocessor.
However, I am a fan of SMP / dual core machines as they enable you to still be productive (on some other task email, calcs, etc.) whilst Catia has tied up one processor /core thinking about something hard.
In the windows SMP world you do not need as seperate graphics adaptor one will be fine.
There are different ways of implmenting SMP at a board level as far as I am aware intel use a shared memory model (both cores address the same memory through the same bus) where as AMD has seperate memory buses for each core. But it is a while since I took an active intrest in achitecture so I could be wrong with current processor.
Dual 64 bit processor will be treated in the same way dual 32bit are. Again as far as I am aware hyperthreading is a additional CPU instructions for assisting in the priotising & processing of other CPT instructions.

RE: more than 1 processor for CATIA
The SMP behaviour between 32bit & 64bit is the same with DMU (includes caching for assembly workbench) and FEA making use of multiple processors as these bits of catia are muti-threaded.
Execution of 64bit Catia is likley to be slower that 32bit Catia as 64bit uses 64bit pointers and these are longer the 32bit pointers and therefore require more processing to manipulate them.
I wote a reasnoble explanation of Catia memory behaviour in this thread http://www

The same goes to any 3D package, like maya, XSI and 3dmax, where the rendering uses as many cpu's you have, but the workflow uses only one, with few exceptions.
the possible advantage in multi-cpu system in this case is the ability (in some cases) to seperate the applications on a cpu level - CATIA on one, UG on the other, and run them in 2 monitors on the same workstation :)
multi-cpu shines in 3D rendering, video/audio encoding, CAE, and all other situations you send the computer to work while you wait.

In cad it could be automatic feature recognicion, in FEM it's the analysis part (not the modeling), and the same goes to CFD and rendering.
all interactive operations are NOT multi threaded. The iea os multi-processing requires certain algorithems which benefit form the division of labor.
