BTW, there are other timeout values which can and should be changed for clusters using TCP_NODELAY sockets (e.g. the full second retransmit timer when sh->users is set and another seldom used 30 second partial packet timer).
The partial packet timer is a 2.0.x vestige, it no longer exists in 2.2.x
Look, face it, parallel processing and clustering are still "uninteresting" in the standard kernel. And I think such a small group of users can live with special local TCP/networking changes in a "beowulf" type package, in fact they already do.
We try hard not to put changes in which handle a special small group of users who have special needs that no-one else has, this is the road to bloat and unmaintainable code. I am, however, not arguing that at some point clustering will be more central and mainstream (ie. common), but this isn't the case right now.
On the other hand, I know that many of your observations will help us improve Linux/TCP generically and for all users, not just cluster folks.
