Out of memory even though the assigned gpu is free #7

Notice that context buffer is created before gpu assignment: https://github.com/lzqsd/OptixRenderer/blob/84b48be7543c46832ec9ad090f96951d5cc6750d/src/optixRenderer/src/optixRenderer.cpp#L514-L525 This could induce serious memory harassment when there are other jobs running on a multi-GPU server. If any one gpu memory is used up, the program will throw out of memory exception and quit, despite that there are plenty of free devices. The gpu should be set before the createBuffer() line in createContext():https://github.com/lzqsd/OptixRenderer/blob/84b48be7543c46832ec9ad090f96951d5cc6750d/src/optixRenderer/src/creator/createContext.cpp#L36

Sorry, I tried your solution, but it did not work? Any other advice?
