I'm getting a couple errors

libOpenCL.so.1: no version information available
[s]tatus [p]ause [r]esume [b]ypass [q]uit => ERROR: clEnqueueReadBuffer() -38

Looks like the broker is able to connect to the compute node but didn't crack anything. Could it be caused by the catalyst drivers installed on the broker? Which leads to my other question. I have two systems, both with GPUs installed. The wiki says not to configure the broker on a compute node but I've also read somewhere that having the broker on a compute node could reduce network chatter?

my setup:
PC-1: Broker Node -- has 6 GPU but not configured for computing yet, acting as broker only
PC-2: Compute Node -- has 8 GPU

Code:
