Hello, At the moment, the HWLOC_FSROOT and HWLOC_XMLFILE environment variables override tool options and application configuration. Is it really the behavior we should have? I'd tend to think that the priority order should be:
- application options/configuration - environment variable - default OS backend. i.e. basically move the HWLOC_FSROOT/HWLOC_XMLFILE interpretation to hwloc_topology_init, before the application can override them through configuration calls. Similarly, HWLOCK_THISSYSTEM would be overriden by HWLOC_TOPOLOGY_FLAG_IS_THISSYSTEM. What do people think? (At least we should probably settle that clearly in the documentation) (and document these environment variables, I didn't know about HWLOC_XMLFILE). Samuel
