Geometry saving errors May 4, 2018, 10:21 a.m.

The original poster this type of error:

“Error saving geometry for : \obj\grid_object1\grid1”

I have found this is usually because of low disk space. Mantra may need to save some temporary files in order to render and if the drives are full it can't do that to render. I got the same thing recently and cleared off space on the drive and it no longer returned that error. Hope that helps.

Cache Simulation Enable and Ram issue April 26, 2018, 3 p.m.

So lowering the cache limit seemed to help prevent the machines from maxing their ram and crashing.

But what I don't understand is this “Cache Memory (MB)” setting doesn't seem to work as expected?

You would expect the machine to start swaping the ram when it reaches the limit but its not happening. For example when the default of 5000 MB is used the machines will peak at over 20,000 MB usage during the caching process, so It's not clear if this is a multiplier per frame or per CPU thread? Would be helpful to know so I can more accurately allocate the ram usage per sim.

Cache Simulation Enable and Ram issue April 25, 2018, 10:50 a.m.

What I don't understand is when I set a memory limit, why doesn't the machine respect that limit and just swap the ram when it needs more. The machine seems to just plow through and use 64 GB of ram, and then crash.

I'm not sure if that's an issue with the machine or with the settings in Houdini to run the sim?
