On some host OSes, the OS may allocate virtual addresses that are larger than can be handled by NVGPU. As a workaround, we noticed that the host OS will not allocate such large addresses when running single threaded. There is no other way to prevent this issue nor is there any guarantee that this workaround will always work...
