this happens for both houdini 12 and 13
centos 6.4
when i write out large files (like *.sim) that are about 1gb or over, my whole computer will restart.
houdini should be able to handle any size files right?
anyone else experience this?
system crash when writing out large(1gb) files

my buddy has been simming a giant smoke simulation on h13 centos 6.3 , file sizes go as much as 30gb/frame. We didnt have any problem, until it started swapping 128gb machine. I dont know if it makes a diffrence, but we are using Lustre filesystem

No No it is not compressed and we also had to have the vel fields, thats why it got so huge, but never the less we were also quiet impressed, it was reaching 3hr/frame at around frame 397 on a dual Xeon e5-2620.

No they are bgeos, with volumes with some extra fields, gradient,velocity rest etc. Oh I can actually show now since the trailer is out.

1:57 altough thats pretty much the beginning of cache, but the sim was used on plenty of shots including close ups, which was pretty impressive we could put the camera showing %30 of the sim yet still had enough detail.
But the image quality there is pretty bad.

You can add whatever extra fields you want to import to the BGEO froim the DOP import fields ,
But I also don't think the sim files are crashing your Houdini, because even if you export or not every field that would be in the sim file is calculated every frame, regardless if you are writing the sim files to HDD or not.
If you have a lot of inputs for the simulation, trying cashing every source to HDD first,
This way you will know your source is not the problem,
So you can focus on the DOP net
Better share a hip file if you can, That would help a lot.

just to be sure, if its an intense sim utilizing %100 of the cpu, it could be a PSU issue also, Usually PSU issues restart the entire systems.

How much Ram have you got? The only restarts Houdini has ever forced is running out of OpenCL ram - but that was before and might be fixed now.
