Get the MemoryResource for the current device.

Returns the MemoryResource set for the current device. The initial resource is a CudaMemoryResource.

The "current device" is the device specified by Device.activeDeviceId.

The returned MemoryResource should only be used with the current CUDA device. Changing the current device (e.g. calling Device.activate()) and then using the returned resource can result in undefined behavior. The behavior of a MemoryResource is undefined if used while the active CUDA device is a different device from the one that was active when the MemoryResource was created.

Get the MemoryResource for the specified device.

Returns the MemoryResource set for the specified device. The initial resource is a CudaMemoryResource.

deviceId must be in the range [0, Device.numDevices), otherwise behavior is undefined.

The returned MemoryResource should only be used when CUDA device deviceId is the current device (e.g. set using Device.activate()). The behavior of a MemoryResource is undefined if used while the active CUDA device is a different device from the one that was active when the MemoryResource was created.

Set the memory resource for the current device.

If memoryResource is not null, sets the MemoryResource for the current device to memoryResource. If memoryResource is null or undefined, no action is taken.

The "current device" is the device specified by Device.activeDeviceId.

The memoryResource must outlive the last use of the resource, otherwise behavior is undefined. It is the caller's responsibility to maintain the lifetime of the memoryResource object.

The supplied memoryResource must have been created for the current CUDA device. The behavior of a MemoryResource is undefined if used while the active CUDA device is a different device from the one that was active when the MemoryResource was created.

Set the MemoryResource for the specified device.

If memoryResource is not null, sets the memory resource pointer for the device specified by deviceId to memoryResource. If memoryResource is null or undefined, no action is taken.

deviceId must be in the range [0, Device.numDevices), otherwise behavior is undefined.

The memoryResource must outlive the last use of the resource, otherwise behavior is undefined. It is the caller's responsibility to maintain the lifetime of the memoryResource object.

The supplied memoryResource must have been created for the current CUDA device. The behavior of a MemoryResource is undefined if used while the active CUDA device is a different device from the one that was active when the MemoryResource was created.
