Sankar Kumar Posted June 6, 2014 Share Posted June 6, 2014 Hi, I am having a big problem on Houdini simulation (Flip, Pyro) cant able to complete full simulation. Each and every time houdini crashes at different Frame. I attached a sample snapshot. Any body please help me. I tried the same simulations in different system. It works fine but my system crashes even a simple simulations. I replaced my motherboard and tried, and i tried Windows 7 & 8 but nothing works Also want to know how much Pagefile size would be used for simulations. My System Details Intel® Core i7-3770 CPU @ 3.40GHz Motherboard Intel DH77EB Graphics Card GeForce 8400GS Total RAM 16.0 GB (4GB Ram * 4) 1TB HDD Any solutions would be nice...

Guest tar Posted June 6, 2014 Share Posted June 6, 2014 it's usually because you are running out of ram. Quote Link to comment Share on other sites More sharing options...
whodini Posted June 6, 2014 Share Posted June 6, 2014 definitely looks like a ram issue. Pull up a task manager when you're doing the sim to see the utilization. Also is your pagefile enabled in windows? usually its on by default, this way if you run out of physical ram you can swap to disk, which is slower unless you have a ssd as the swap, but thats still not as fast as having physical ram.

NSugleris Posted June 6, 2014 Share Posted June 6, 2014 Ram, I had this exact problem on a project recently. I would be able to get it to stay stable sometimes if I did the whitewater passes seperately and the ram would cap and each frame would take an hour or so. Clear the ram, resume the $SF.sim sim frame and then it will sim much faster. 32 Gigs+ for larger white water passes etc, is really nice.

Sankar Kumar Posted June 7, 2014 Author Share Posted June 7, 2014 Thanks for the suggestions... I have another doubt. Is the speed of Hard disk may cause this memory issue. Is any body using SSD type hard disk for houdini. Quote Link to comment Share on other sites More sharing options...
tricecold Posted June 7, 2014 Share Posted June 7, 2014 Yes feed us more info, 16GB Ram may sound a lot but it is quiet limited for medium scale sims. flip sims tends to get bigger and bigger in memory on windows. there is a hack/fix but ofcourse this is not officially supported. If you think your sim is not so much detail yet you are running out of memory, you can try this hack/fix http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=30531&highlight=memory+leak The immediate workaround is to use the VC11 Houdini build on Windows and then copy/replace the tbbmalloc_proxy.dll over from a H12.5 install into H13.0. This will forcefully disable tbbmalloc_proxy. or try ubuntu 1 Quote Link to comment Share on other sites More sharing options...
NSugleris Posted June 7, 2014 Share Posted June 7, 2014 (edited) What build are you running ATM? I'll have to download 10.0.322 to see if it fixes the issue. On that forum post its supposed to be fixed. "On Windows, Houdini 13.0.322 now uses the latest TBB version (4.2 update 2), which contains the improved memory allocator.

" Hi i am using Houdini 13.0.416 now, i think my machine crashing on all versions of houdini 13, Now i will try houdini 12.5 in my new system... Previously i use houdini 12 without any issues If H12 fails in my new system I will try ubuntu... I luv odforce forum without it learning houdini is tough for me...

NSugleris Posted June 9, 2014 Share Posted June 9, 2014 Damn, that's too bad the issue seems to still be there. Linux Mint partition I go. Quote Link to comment Share on other sites More sharing options...

Sankar Kumar Posted June 15, 2014 Author Share Posted June 15, 2014 unfortunately that still seems to be a problem on Windows This problem not only affects Houdini simulations.. It makes my system unstable and creates Blue Screen error frequently even houdini is not in use and my system is Idle... I don't know why? But After i replaced "tbbmalloc_proxy.dll" from Houdini 12.5 my system as well as simulations are stable now.... Quote Link to comment Share on other sites More sharing options...
edward Posted June 16, 2014 Share Posted June 16, 2014 creates Blue Screen error frequently even houdini is not in use and my system is Idle... I don't know why? Have you tried running an overnight memory test on your system? Blue screens like that sound like bad memory to me. Also, make sure you ensure your computer is "hot" before starting your memory test because sometimes those memory defects don't show up when everything is cool.
