is it possible to run this code using a python node? Every time I try to run the code Houdini ends up freezing. Seems like you can't use the multiprocessing module does anyone know if this is the case?

No that's not going to work for a multitude of reasons. The multiprocessing module is spinning up a bunch of child processes to perform the work, and so the computed result has to be returnable to the parent process as a value. Your example tries to create a new node in the child process which (even if it worked via a correctly bootstrapped hython process) couldn't be passed back to Houdini as a value.
A python node is even further restricted - you're expected to only change the data local to the node. Exactly what that data is varies by context.
