How To Increase Cpu Usage When Creating A Cach

[cah8222]

Everytime when I'm creating a particle or a fluid cache, I find that my cpu usage is always less than 20%.

Does anyone know how to increase the cpu usage and speed up creating a cache?
Is there a function, such as batch render, which can let you choose how many processor you'd like to use when creating a particle or fluid cache in Maya?

By the way, there are 4 dual core cpu in my computer.

I do appreciate if someone can help me out.

Theres no switch to adjust it will do it as fast as it can. In any case not all a calculation can be converted into parallel computation (or atleast very effeicient one). In fact very few things can effectively be paralellisized. I think they have something dfone to make this happen in 2009 but still its not a entirely trivial thing as the look of fluids get affected by solve order.

So having 500 parallel computers dont necessarily make all tasks fast, as most things you do is single threaded. In this case its a buit hard since the computations are coupled. This si why 2 types of super computers exist.

In any case theres a second factor at play, caching is also dependent on the speed of your deck (disk bundle), wich can be the bottleneck.

yup, your I/O bound, so get a raid if you want to go faster.

thank you for the reply.

Launch Maya twice and compute the same ncloth scene from different points in time.  No, I'm not kidding!  This works surprisingly well.  I cut my sim time almost in half on a very heavy ncloth scene, and I only had 3gigs ram at the time.  I always wanted to try opening 4 instances of Maya on a quad processor machine (with more ram) to see if method could be pushed farther.

You do have to merge the two ncloth caches when you're done and you'll need to have some overlap to blend with.  Make sure the split point is at a slower/less crucial point of your animation.
