Trying out Blender      Flip Fluids      – currently baking below lighthouse.blend sample file, 2-3 days so far, about 10 hours go go and 89Gb cache space used up!

Final space cost and rendered frame one, as of 5/29 6am [frame 0 rendered in 2.5 mins]



After 60 frames l got….

So far l have only been able to render up to 149 frames, then l get a cuda out of memory crash. I use both a GTX970 with 4Gb and a GTX1080 with 8Gb, l’ve tried with both and with each cards. Will keep you updated, meanwhile heres a render of the 149 frames








NVIDIA CUDA 8 with LinuxMint

Notes, screenshots and results using, installing, testing Nvidia Cuda on Linuxmint 18.1

“CUDA is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).

Tests done on my custom built Workstation PC as well as Alienware 17 laptop – all GPU specs below.

Quick comparisons [not the focus of this post]  :):

  • Puget systems laptop, with a GTX 980M 8Gb  – 91 billion int./sec, 1819 Gflops
  • My Alienware 17 with a GTX 860M 2Gb – 43.3 b.i.p.s, 866 Gflops
  • My workstation with a GTX 970 4Gb -> 146 b.i.p.s, 2919 GFlops.

Screenshots in no particular order.
