Right, UTK did quite a lot of work on optimizing collectives over KNEM and looking at the impact on several applications. Have a look at the bottom of http://runtime.bordeaux.inria.fr/knem/ for references. On the Inria side, we mostly focused on KNEM itself, the main publication about this lower-level side of the software stack is the 2013 JPDC article (there's a link in the above URL too). Brice
