Re: CPU speed slowing down

I don't know about Cadcamnet, but Anandtech has a report today to the contrary.

is Intel's "roadmap" for this year. In Q1, '04, they will have a 90nm, P4, 3.4ghz, 1mb cache unit and by Q4, '04 they will have a 90nm, P4, 4.0 ghz, 1 mb cache piece on a new socket called LGA-775. Seems like a fair bit of advancement to me.

Microns bring you more GHz and more transistors. You need more transistors for 64 bits.

64 bits brings you essentially more RAM, not much more power for CAD (floating point).

But you also need more transistors for dual cores processors, which will bring you true dual processing at lower cost and without the FSB bottleneck.

*IF* SW was preparing its code to take advantage of multiprocessing (parallelisation, thread-safe, ...) it *COULD* explain some speed/reliability issues in the latest versions and *WOULD* open a brighter future... Just my 2 eurocents guess...

That's certainly plausible. Dual cores are coming, both for Intel and AMD. The only issue is the fact that SW has always denied that there was any useful parallelism in solving models. Any speculation where they could actually find some parallelism? I'm thinking assemblies are a candidate, since more than one model will need to be updated in many rebuilds. What about individual parts? Could the FMT be analyzed for independent branches?

Certainly.

Check your parts FMT (which is actually a graph) with

;-) There could be some parallel branches, but it's not enough to process them in parallel. Think about a cube with 2 holes on different faces that intersect in the middle of the cube : the FMT show them as parallel, while the faces actually depend of each other...

I believe parallelism can be exploited at an even finer grain, for example to compute faces in shells. But these are more related to Parasolid than SW.
