APIs tested: hipMemcpy, hipMemcpyAsync, hipMemcpyHtoD, hipMemcpyHtoDAsync
hipMemcpyDtoH, hipMemcpyDtoHAsync, hipMemcpyDtoD,
hipMemcpyDtoDAsync
-Scenario-1:: The aim of this test case is to cover all the negative test cases
for 8 hipMemcpy apis
-Scenario-2:: This test launches NUM_THREADS threads. Each thread in turn tests
the working of 8 hipmemcpy apis
-Scenario-3:: This test case verifies the working of Memcpy apis for range of
Memory sizes from smallest one unit transfer to 1GB.
SWDEV-238517 for enhancing hip unit tests
