You need access to the source in order to look at the decision maps.
They are in ompi/mca/coll/tuned/coll_tuned_decision_fixed.c file.

hello all,
i want to measure the time needed for collective operations on a cluster
by using ompi 1.2.5. i read that the algorithm which is used depends on
msgsize and/or commsize and ompi constructs a decision map for the
collective on the system. now my question:
where can i find these decision map for my system?
i'm no sysadmin, but i hope there is a way to get this information
anyway ;-).
regards,
andy
