The enumerations are described as follows:

• MEMORY_TYPE_DEFAULT: default type of device memory, which can be obtained by calling the aclrtMalloc API provided by AscendCL. When allocating memory, pass one of the three enumerated values of aclrtMemMallocPolicy, which are ACL_MEM_MALLOC_HUGE_FIRST, ACL_MEM_MALLOC_HUGE_ONLY, and ACL_MEM_MALLOC_NORMAL_ONLY.
• MEMORY_TYPE_P2P: type of inter-device memory, which can be obtained by calling aclrtMalloc. When allocating memory, pass one of the three enumerated values of aclrtMemMallocPolicy, which are ACL_MEM_MALLOC_HUGE_FIRST_P2P, ACL_MEM_MALLOC_HUGE_ONLY_P2P, and ACL_MEM_MALLOC_NORMAL_ONLY_P2P.
