/* This testcase is mostly the same as alloc-8.c.
However, on systems where the numa and/or memkind libraries are
installed, libgomp uses those. This test ensures that the minimal
features work. Note: No attempt has been made to verify the parition
hints interleaved and nearest as the kernal purposely ignore them once
in a while and it would also require a 'dlopen' dance.
memkind is used for omp_high_bw_mem_space, omp_large_cap_mem_space
and partition = interleaved, albeit it won't be interleaved for
omp_large_cap_mem_space.
numa is used for partition = nearest, unless memkind is used. */
