Hello all,

for a new development effort[1] in the PLPA sub project[2], we/I need
actual data from running machines. Concretely the cpu topology information
which the linux kernel >= 2.6.16 exports per sysfs.

Those who are willing to help please follow the instructions at the end of
the mail.

Most interestingly are machines with multiple NUMA nodes, enabled
HyperThreading (HTT) and multi-cores.

Thank you very much.

Bert Wesarg

Instructions:

# assume you have mounted the sysfs on /sys
$ cd /sys
$ tar cjf cpu-topology.tar.bz2
devices/system/{cpu/cpu*/topology/*,node/node*/cpu*}

Please give a short description of the machine and send the
cpu-topology.tar.bz2 to the list.
