 * This testcase verifies D2D functionality of hipMemcpyParam2DAsync API
 * Where Memory is allocated in GPU-0 and stream is created in GPU-1
 *
 * Input: Intializing "A_d" device variable with "C_h" host variable
 * Output: "A_d" device variable to "E_d" device variable
 *
 * Validating the result by copying "E_d" to "A_h" and checking
 * it with the initalized data "C_h".
