Hello Houdini guys!

I have problem with caching fluids when OpenCL option is on.

Here is error lines from console

OpenCL Exception: clEnqueueNDRangeKernel (-4)OpenCL Context error: CL_MEM_OBJECT_ALLOCATION_FAILURE error executing CL_COMMAND_NDRANGE_KERNEL on GeForce GTX 750 Ti (Device 0).

I have installed CUDA + Lastest NVidia drivers
I look on About Houdini info

Open CL is enabled.

Any help will appreciated!

The error reads as a memory error - probably out of vram. Try a GPU with more ram or the OpenCL CPU option.

Thank you for the answer! Can you tell where I can turn ON OpenCL CPU option?

You have to install a CPU driver and point OpenCL to it using the right HOUDINI_ env variable. Hopefully in H16, it will be a toggle i.e. “Run on CPU” if “Use OpenCL” toggle is enabled.
