Get the status of the primary context. Returns whether the current context is active, and the flags it was (or will be) created with.

Requires CUDA-7.0.

Specify the flags that the primary context should be created with. Note that this is an error if the primary context is already active.

Requires CUDA-7.0.

Destroy all allocations and reset all state on the primary context of the given device in the current process. Requires cuda-7.0

Requires CUDA-7.0.

Retain the primary context for the given device, creating it if necessary, and increasing its usage count. The caller must call release when done using the context. Unlike create the newly retained context is not pushed onto the stack.

Requires CUDA-7.0.

Release the primary context on the given device. If there are no more references to the primary context it will be destroyed, regardless of how many threads it is current to.

Unlike pop this does not pop the context from the stack in any circumstances.

Requires CUDA-7.0.
