libgomp/testsuite/libgomp.c-c++-common/alloc-11.c

/* This testcase is mostly the same as alloc-9.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.  */
