--- Comment #1 from Bruce Cherniak <bruce.cherniak at intel.com> ---
We've seen a similar problem with apps using TBB as their threading model. 
OpenSWR creates its thread pool when the OpenGL context is created and, by
default, binds threads to physical cores.

Two things you might try:
1) Create your application thread pool before creating the OpenGL context.
2) Set the KNOB_MAX_WORKER_THREADS environment variable to limit the number of
threads that OpenSWR creates.  This also tells OpenSWR to not bind threads to
cores.  Setting it to 0 may work in your situation and still enable the full
number of OpenSWR threads.
