Is there a method to share the GPU between two separate OpenCL capable programs, or more specifically between two separate processes that simultaneously both require the GPU to execute OpenCL kernels? If so, how is this done?

It depends what you call sharing.
In general, you can create 2 processes that both create an OpenCL device, on the same GPU. It’s then the driver/OS/GPU’s responsibility to make sure things just work.
That said, most implementations will time-slice the GPU execution to make that happen (just like it happens for graphics).
I sense this is not exactly what you’re after though. Can you expand your question with a use case ?
