That's why you should have a separate 100Mb network for NFS traffic and other crap like that, then have a 1Gb network for your actual calculations, MPI traffic, etc. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFDghRCXVaO67S1rtsRAlpkAJ4vs6ROMe1TF4IcwNoyANTMtDjmfQCgwcGI xzSx4qUzq2cLje32i0DD0hw= =Ps1N -----END PGP SIGNATURE----- -- [email protected] mailing list
