[novice] Running python script on new session

[art3mis]

I have the following script to recursively turn on 'OpenCl' in all my nodes.

First question, how would I run it once, simply paste into a new Python shell or??

2ndquestion, how would I get this to run every time I start a new session?

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/geometry_node_name'),

There is a mechanism called 123.py which runs when you launch Houdini. I have not used it but you could try searching the help on that.

This is what you need.
