Hi, I am using numactl-2.0.8-rc3 on a large server machine with 8 NUMA nodes and 8Gbyte of memory per node. I ran a test application compiled using numactl-2.0.8-rc3/test/tshared.c. I understand that this piece of code allocates memory pages as interleaved on all numa nodes. Later the application gets the memory policy (MPOL_F_NODE|MPOL_F_ADDR) for the pages allocated and prints out deviations from round-robin allocation if any. In my tests I find a huge bias and deviation from the expected round-robin allocation. Around 90% of the pages are allocated on node#0. I tried numa_set_strict(1) but numa_alloc_interleaved does not honor this flag in agreement with the documentation. Please explain this behavior to me. Must I patch numactl to enforce round-robin strictness?
