Houdini Lounge » Setting Open CL device

illusionistics
hey, did it work with the “_DEVICENUMBER” in your case? When trying it I get
an “incorrect device number” exception in Houdini -
could you perhaps hint me on how to switch the buses instead of the slots?
(Got this crappy optimus notebook and it defaults to the intelHD as openCL device
on Win - while on Linux (same device, employing bumblebee) the nvidia card
is used for both (GL/CL), as desired + it´s about twice as fast.
Would love to get this working on Win too…),
thnx + cheers!

Hi yes - HOUDINI_OCL_DEVICENUMBER = 0
worked perfectly for me

As Artye says: go to: help>about houdini>show details - to check and then try either 0 or 1 as device number.

Hi there, quick question about choosing the gpu i want to be my open cl device..
i have a GTX1080 in slot 1 with no displays and a 970 in slot 2 and it handles both my displays. Id like to use the 1080 for open CL.

Is this the correct command to add to my env file?

HOUDINI_OCL_DEVICENUMBER = 1

Thanks in advance

While there are now more tools that make it easier (UV flatten being one), I can recommend checking these out:

this works nicely get get everything “unitized”. Enter the expression in the uniform scale parameter of the transform sop. I just have it saved as a preset.

1/max(max(bbox(opinputpath(“.”,0), D_XSIZE), bbox(opinputpath(“.”,0), D_YSIZE)), bbox(opinputpath(“.”,0), D_ZSIZE))

i have this same problem, my issue: “bad parameter reference” on any light I have to manually delete the “sun angle” on the distant light tab, even if I save this as a permanent default when I next start houdini the issue is back. Any ideas? Did u fix your problem?
