Anyhow, sufficiently recent Linux does expose the information (under /sys/devices/system/node/), it's just that PLPA doesn't use it by design. I guess that it would be a fairly straightforward project for someone to try replacing PLPA with hwloc without needing to know much about GE internals. If anyone is interested, see http://www.open-mpi.org/projects/hwloc/doc/v1.1.1/switchfromplpa.php As well as helping with architectures like Magny-Cours, it would introduce support for more platforms than Linux and Solaris. _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
