lazza79 Posted March 13, 2017 Share Posted March 13, 2017 Hi Guys, I have a simulation with roughly 50K RBDs and 27K constraints. All the rbds are packed (using mid button H16 says that they occupy 40mb instanced) but still, when I perform the sim, it takes up all my ram 63.8Gb. Is there a way I can debug this? How do I know what is taking memory? Thank you! Lazza Quote Link to comment Share on other sites More sharing options...
Atom Posted March 13, 2017 Share Posted March 13, 2017 I guess you would use the Performance Monitor to try to determine where memory consumption is the greatest. Really? 50,000 RBD objects. Whew that is a lot. If your motherboard supports up to 128GB maybe you could upgrade your memory? Quote Link to comment Share on other sites More sharing options...
lazza79 Posted March 13, 2017 Author Share Posted March 13, 2017 Thank you Atom, Performance monitor, afaik, actually only returns the times of the single processes... am I wrong? My MB can be upgraded to 128 but it's too expensive... Thanks! Lazza79 Quote Link to comment Share on other sites More sharing options...
lazza79 Posted March 13, 2017 Author Share Posted March 13, 2017 Ops, I just realized that I can enable "memory stats" in the Performance editor.... Now I know where is the mem consumption, the problem is I don't know why... 1 Quote Link to comment Share on other sites More sharing options...
cwhite Posted March 13, 2017 Share Posted March 13, 2017 Around 10GB of memory usage in the Bullet solver is in the ballpark of what I'd expect for a sim of that size. Is there any indication of what nodes account for the other ~50GB (perhaps SOPs for the simulation's input geometry)? Quote Link to comment Share on other sites More sharing options...
lazza79 Posted March 13, 2017 Author Share Posted March 13, 2017 (edited) actually, this result is just after 30/40 frames. Most of the rbds are still inactive... You mean outside the dop? I mean, where the dops "points" for the RBD packed geos? Edited March 13, 2017 by lazza79 Quote Link to comment Share on other sites More sharing options...
cwhite Posted March 14, 2017 Share Posted March 14, 2017 Yeah, I meant the SOP network where the RBD objects' geometry comes from Quote Link to comment Share on other sites More sharing options...
