How to switch to GPU or OpenCL for all the sims, cache and viewports.

[cgartashish]

Hi,

Please let me know if there is a simple setting in preference where we can enable or switch to GPU or OpenCL. I am not sure whether viewport uses GPU, I think it does and I would also like to know if we can directly switch a DOP node to use GPU for its calculations. Can Mantra and Arnold use GPU? 

Please let me know the specific settings. Thanks again.

def set_opencl(parent_node, parm_value):
    for node in parent_node.allSubChildren():
        for p in node.parms():
            if p.name()=='opencl':
                try:
                    p.set(parm_value)
                except hou.PermissionError: #this handles the case that the parm is inside of a locked .otl
                    pass

hou.session.set_opencl(hou.node('/obj/dopnet1’), 1,)

if you put this function into the session module you can enable or disable opencl in a dopnet using the last line of code with either 1 or 0 as the last argument
