opencl error with viscous flip sim

[XRM]

Hi fellow FX artists. I was recently doing a sim which required viscous liquids. I wanted to try the opencl option with helps to calculate pressure and viscosity on a graphics card. I am getting this error

My version of Houdini is 15.0.244.16

 

This use to work fine on houdini 14.

First thing to try is a later H15 build. The initial release is 200+ days old.
