Re: [BProc] Question about Filesystems

[Greg W. <gw...@la...>]

It really depends on your application. For small clusters mounting home=20=

via NFS seems to be the best alternative. When you get up to 256+ nodes=20=

or you need to do high-speed parallel I/O, NFS just does not cut it.=20
For this type of application both Panasas (http://www.panasas.com) and=20=

Lustre (http://www.lustre.org) look like promising alternatives.
