So I am trying to test the heightfield erode tool and am getting the error “OpenCL exception: clCreateProgramWithSource(-34)”. My system specs are listed below. Anyone else get similar errors?

OSX El Capitan
Processor: 2 x 2.66 GHz 6core intel xeon
Memory: 64 GB
Graphics: NVIDIA Quadro 4000

Houdini: 16.0.671

MacOs now supports OpenCL CPU but is quite buggy. Can you type hgpuinfo -l in the Houdini Terminal.

Sorry that I haven't replied until now. It seems that Sidefx isn't sending me notifications for subscribed posts.

I ran the command and this is what I got back.

The OpenCL exception at the end doesn't look promising though.

Looks like you need a new graphics card. Houdini needs OpenCL 1.2 and that card is meant to support 1.1.

You could try OPenCL CPU but it is just for compatibility more than speed.

from the Houdini Terminal.app you can put 
 export HOUDINI_OCL_DEVICETYPE=CPU
and then type 
hgpuinfo -c
. That should show the Xeons being used.

If it works then put 
HOUDINI_OCL_DEVICETYPE=CPU
into the houdini.env file.
