[erlang-questions] very large distributed implementation?

Scalaris probably has been tested with many nodes but you would probably
need to check their IEEE paper, or the presentations

Cloudi exists but is not meant for 100s of computing nodes
(http://cloudi.org).  The reason is that private clouds with new
hardware would have many cores, so the need for many nodes is reduced.

Any Erlang code that works on 100s or 1000s of nodes is unlikely to use
the distributed Erlang mode because of the heartbeat message that is
used every minute (i.e., so local network backbones that are not
expected to go down).  That means that such Erlang code is likely to
utilize tcp, udp, etc. with custom code that manages consistency.
