No, it hasn't been tested on 1000 nodes as yet. The largest cluster we've tested on is about 128 nodes. A "large cluster" jgroups config will be based on what we used here. Expect to see a wiki page on this pretty soon. I do know of people in the community testing on up to 400 nodes; I don't have access to these configurations though.
