Hi Brice! Thanks for the quick response! Yes, 64bits works as expected. It is strange, but `lstopo -v` returns the correct output: ``` Machine (P#0 total=12333504KB Backend=Windows OSName=Windows WindowsBuildEnvironment=MinGW OSRelease=10...
Yes, no problem. GitHub restricts the XML attachments so I changed the file extension to `.txt`. [hwloc_topology.txt](https://github.com/open-mpi/hwloc/files/5816243/hwloc_topology.txt)

Here are two attached files with the debug output generated by [the provided below packages](https://github.com/open-mpi/hwloc/issues/444#issuecomment-760965354): - [32bit log](https://github.com/open-mpi/hwloc/files/5829272/hwloc_cpukinds_debug_output_intel64.txt) - [64bit log](https://github.com/open-mpi/hwloc/files/5829273/hwloc_cpukinds_debug_output_ia32.txt)
Sorry, but I have no access to the machine at this moment. So I would check proposed options later.

Yes, I got it right now! This sample returns very strangely values: ``` C:\temp\kivan>windows-cpukinds-example.exe efficiency class 59 efficiency class 69 efficiency class 101 efficiency class 0 C:\temp\kivan>windows-cpukinds-example.exe efficiency class 105...
It is strange, but they were different when I ran it 3 first time, but now it looks reproducible: ``` C:\temp\kivan>windows-cpukinds-example.exe efficiency class: 0 group affinity: 3 efficiency class: 97...
