*count the number of devices with compute capability greater or equal to 1.0 that are available for execution. If there is no such device,
cudaGetDeviceCount() returns 1 and device 0 only supports device emulation mode. Since this device will be able to emulate all hardware features, this device will report major and minor compute capability versions of 9999.
|count ||- Returns the number of devices with compute capability greater or equal to 1.0|
- Note that this function may also return error codes from previous, asynchronous launches.
