Recommended Posts

Hi!

I trying to simulate a DOP dynamic

and become у amssage that houdiny has memory allocation error..

What`s wrong?

There could be many reasons. However, if you're using an ATI video card, it's because there is a memory leak upon every redraw in the driver.

Which driver? If you're running an 8X.XX series video driver, you better have HyperThreading turned off. If you want to keep HyperThreading turned on, then you will need to go back to an 7X.XX series video driver.

If that doesn't work, do you have have a hip file that demonstrates the problem?

We have still memory allocation errors here on our side. HT is disabled and we're using FX 3400 PCIe cards with driver version 81.67. We never managed to simulate more than 100 frames in one go. This problem has really something to do with the graphic card?

Actually I also have the problem of "memory allocation error" (and subsequent houdini crash) when caching in SOP, and often in COPs ... is there a way to make houdini just tells you "hey dude!.. i'm on 32bit platform.. so i cant use further memory" instead of just crashing?

cheers.

Deactivating the "Cache Simulation" option in the dopnet operator seems to fix the memory allocation crash, at least for the moment.

However, I think Houdini should be capable to cache some hundred frames RBD.

If anyone on this thread could post a hip file (and describe the steps required to duplicate the crash), that would go a long way towards helping us figure out what is going wrong...

Thanks,

Mark

As soon as I have time I will strip down a demo scene for reproduction this week because the actual scene contains confidential material.
