1. Create a set of mini numa interface. In Linux, the interface is based on system call rather than libnuma. In Windows, the interface can also work, but the policy class is dummy. Different from Linux, Windows doesn't provide numactl tool or numa lib to setup numa policy, thus the default policy is followed in Windows, that is, using the closest host numa node to allocate pinned host memory in hipHostMalloc(). To get the closest host numa node of a GPU device, you need query the new attribute hipDeviceAttributeHostNumaId. Then you can create a thread with CPU affinity on the numa node. For example, reference the test in hip-tests/catch/perftests/memory/hipPerfHostNumaAllocWin.cc. 2. Remove pfnSetThreadGroupAffinity and pfnGetNumaNodeProcessorMaskEx as the functions have been exposed since Win7 and Win server 2008. 3. Other minor fixes.
