I don't if the GTX 780 Ti allows for multiple context given that it's a graphics card and not a compute card.

If it does, then check to see if the compute mode is set to "Exclusive" ( i.e. run "nvidia-smi -a" and look for "Compute Mode").

If you're running on Windows, then it might be the WDDM driver that's inhibiting multiple context creation. You may need to use the Tesla Compute Cluster (TCC) driver, which on Windows is only available for Tesla cards.
