Actors and fast networks

Hi,

I wonder if some Actor frameworks (Akka?) could use fast networks, such
as Infiniband or Myrinet, and if someone has already tested it?

I guess JFS could be used transparently (as explained on
http://jfs.des.udc.es/docs/jfs.html ) however it would not take
advantage of the API extension.

Also, if anyone has compared JFS performances to a native MPI
application, I'd be glad to see the results. :-)

Thanks
Sylvain
