property GPUOverlap: Boolean;
Specifies if device supports overlapping copy and compute operations.
Returns: Boolean
Remarks:
With devices 1.2 and later, it is possible to overlap kernel execution on the device with data transfers between the host and the device. With devices 2.0 and later two independent copy engines are capable of simultaneous copy in two directions concurrent with device computation. In order to overlap computation and copy operations at least two command queues need to be created for the device and device must support multiple command queues.
