MilanSuk Posted January 1, 2014 Share Posted January 1, 2014 (edited) There is no better way how to start the New year than smoke your GPU BulletSOP 2.5 preview features implementation of WIP Bullet Library 3.0 with OpenCL(CPU/GPU) support. Please keep in mind that this version supports only fraction of BulletSOP features and It's only for testing and highly unstable! For OpenCL settings, check btSolver node -> Advanced tab! You can activate "old" CPU solver(which has some bugs unlike BulletSOP 2.0.10) and compare result and speed. Testing scene includes 80K boxes(of course you can try to go higher - change settings on OpenCL tab). And If you want to publish some result(s) it's better to restart Houdini(clean memory) before running final simulation. So Let's try it and let us know about your results! Best wishes,Milan Suk BulletSOP binary is free of charge, but You can make a donation and help keep the project running. It's up to you!Download BulletSOP v2.5 preview for Windows(compile on Houdini 13.0.260): bit.do/bulletsop_2_5_preview PS: This is my result on 3 years old GPU!

papicrunch Posted January 6, 2014 Share Posted January 6, 2014 It s look very impressive ! Nice job. Are there some limitation to using opencl ? And is your opencl implatation compatible with the intel cpu opencl? Have fun, and thank you for your epic contrubution to houdini community Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted January 6, 2014 Author Share Posted January 6, 2014 (edited) Thanks to all of you Nice job. Are there some limitation to using opencl ?And is your opencl implatation compatible with the intel cpu opencl? Limitations are same like a DOP Gas(Smoke) solver -> It's better to keep data in OpenCL memory and GPU which has smaller(and more expensive) memory doesn't allow to simulate large scenes. Example runs on Intel CPU as well, but It's slower Edited January 6, 2014 by MilanSuk Quote Link to comment Share on other sites More sharing options...
Skybar Posted January 6, 2014 Share Posted January 6, 2014 Amazing work Milan! Thanks to all of you Limitations are same like a DOP Gas(Smoke) solver -> It's better to keep data in OpenCL memory and GPU which has smaller(and more expensive) memory doesn't allow to simulate large scenes. Example runs on Intel CPU as well, but It's slower It's slower than GPU OpenCL, or slower than the "normal" BulletSop? Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted January 6, 2014 Author Share Posted January 6, 2014 Amazing work Milan! It's slower than GPU OpenCL, or slower than the "normal" BulletSop? CPU OpenCL is slower than GPU OpenCL - I measured it on Intel i7-3820(3.6GHz) vs. Nvidia GTS450. Feel free to download it and try it on your HW!

OrangeSed Posted January 6, 2014 Share Posted January 6, 2014 Thanks Milan, really nice and a happy new year But is it possible that you compile it for H12.5? Would be amazing! Cheers, Andreas Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted January 7, 2014 Author Share Posted January 7, 2014 But is it possible that you compile it for H12.5? Would be amazing! This is only preview and at this moment only for Win64! Final version will be for all OS(s) and H12 and H13! Quote Link to comment Share on other sites More sharing options...
