ITP: pvfs
[ you might have seen this on debian-devel, figured this would be the
better forum ]
I'm going to tackle packaging pvfs.
PVFS makes use of the leftover disk space in a cluster, presenting one
great big file space to applications. ( 3 extra gigs on 10 nodes, 30
gigs of space to play with). Reads and writes to a file can be
executed in parallel (an MPI job doing file i/o on distinct chunks of
a file, say )
PVFS is GPL, and you can read more about it at
http://parlweb.parl.clemson.edu/pvfs
It's going to be a bit tricky to package: on the server side there's
a metadata server running on one host, i/o servers running on N
machines. On the client side, there is a C API one can code directly
to, or one can use a kernel module and a userspace daemon to pretend
the PVFS system is a regular unix-like file system.
