Hello John, Your list is basically OK. Some comments below. > [ ] hwloc-bind > - not tested. This seems important enough to test. Basic testing is easy, but it becomes annoying when you want to test things that may not be supported by the OS. Testing CPU binding on Linux should be easy. Memory binding too if you check whether the machine is NUMA first. > [ ] hwloc-ps > - isn't tested and that seems like it would be easy to test.

I'd be interested to see if you can get something to work. > [x] lstopo > - tested by utils/hwloc-ls.sh > [x] lstopo-no-graphics > - tested by utils/hwloc-ls.sh These are actually very basically tested. We store most lstopo output to a file but we don't check its content at all. Obviously, the output depends on the machine, so in-depth testing isn't easy. But right now, we somehow just check sure they don't crash. > = tests/linux/test-topology.sh = > > "This directory contains tarballs of Linux sysfs hierarchies collected on sysfs + some files from /proc and /proc/device-tree when it matters. > various systems.

And set_xmlbuffer() for reimporting what we exported. Brice
