Hello Your problem may be related to the fact that same policies are identical on some operating systems. For instance DEFAULT and FIRST_TOUCH are often identical. What did you set and what did you get back? There are many examples in the tests subdirectory, in doc/hwloc-helloc.c and in hwloc/helper.h and hwloc/inline.h, but I don't think we have much about the membind API, and this API isn't a easy one unfortunately (given the variety of existing policies and operating systems).
