Speed Up Pyro FX Simulation Using OpenCL - Houdini Tutorial
In this video we have three pyro tests and we will compare between the simulation speed using CPU only simulation and using GPU acceleration "using OpenCL" with the CPU for the simulation ..
*First Test: Smoke Cluster
------------------------------------------
Pyro Division Size = 0.105
Frame Count = 500 Frames
*Simulation Fully Cached to System Memory.
*Second Test: Billowy Smoke & Animated Object
------------------------------------------------------------------------------
Pyro Division Size = 0.045
Frame Count = 400 Frames
*Simulation Fully Cached to System Memory.
*Third Test: Fireball
-------------------------------
Pyro Division Size = 0.051
Frame Count = 100 Frames
*Simulation Cached to a limited System Memory (10 GB only).
*Workstation Specification:
--------------------------------------------
CPU : 2 X Intel Xeon E5-2640 v4 @2.40 GHZ (10 core each CPU, total 20 cores) "@ default clock speed".
GPU : MSI GeForce GTX 1070 "@ default clock speed", 8 Gbps, 8 GB GDDR5, Bandwidth: 256 GB/sec.
Ram : 64 GB.
*The software that used in this video to monitor CPU, GPU and RAM usage is "MSI Afterburner Software".
