Hello Jorge, I've just noticed Servet in the ipdps 2010 proceedings. There are probably interesting things to do between Servet and hwloc http://www.open-mpi.org/projects/hwloc/
On one hand, servet could use hwloc to get binding implementations on various OSes. Indeed, Servet version 1.0 actually doesn't even build on Debian Linux systems: you need to #define _GNU_SOURCE before including <sched.h>, and then use CPU_ZERO/CPU_SET instead of __CPU_ZERO/__CPU_SET, and these are specific to Linux of course. Just using hwloc for that part will provide you wide OS support. On the other hand hwloc has the following TODO item: on OSes or systems which don't know the cache size and sharing from the hardware itself, just find out from measures, which is exactly what Servet just does :) Ideally, Servet would be using the BSD licence but it's currently GPL. Maybe a compromise would be to make Servet a library which some BSD plugin of hwloc could be compiled against if the user already has Servet installed. That would need Servet made a library. What do you think? Samuel
