networking options

[Matthew Timothy Pratola]

Hi all,

Just looking for some information and/or recommendations on the various
networking options available for building beowulfs.  The beowulf in
question would consist of ~1000 nodes.  I'm aware of myrinet, dolphonics,
fiber and of course the ethernet options.  Also of concern is topology.
If any of you can expand my knowledge (or point me to articles which will
help me) in this regard, it is much appreciated.  Even practical
experience in terms of real-world latency, throughput and reliability of
these various options would be helful, as well as knowing if they require
the use of a proprietary MPI implementation (bad for us).

thanks,

Matt
