disable opencl and preconditioner faster than enable each of them?
im using houdini 17.5
my cpu e5-2695 v4*2
my gpu quadro p5000

this is my test resuit(fluid)
3.12 opencl
2.32 preconditioner
2.29 disable all

this my project

didn't check your setup but it shouldn't be a surprise - preconditioner is for quad-core setups IIRC, openclgpu runs across the slow PCI bus. 1 puny gpu card vs 72threads of cpu goodness…

Try openCL CPU, in misc prefs. in theory that should be faster .

thanks, I was wrong, I thought that opencl means something like cuda can speed up by gpu and cpu ,does houdini has gpu acceleration or somthing like that?

opencl cpu 2.47, disable still win, strange

that machine is beast!

what? no no no
I forgot to save when I uploaded the file,thats my 100 frames resuit
seriously???15m,8m???
500frames:
28m28s
I am really confused now , thats crazy

AH I see your test now, at the object level where it meshes, so…

CPU only
100 frames 1m 45s

Linux should give you a boost. OpenCL doesnt affect 100 frames that much. It only works on the viscosity and pressure in DOP land IIRC - good news, though, H18 optimises flippy

version 18 going to be very impressive for large scale with my 2990wx muahahahaha

It’s amazing, I will definitely buy amd next time.
