Subject: [Lustre-devel] Vector I/O api
Date: Fri, 11 Jul 2008 21:56:07 -0600	[thread overview]

Tom -

In a recent call with CERN the request came up to construct a call that can
in parallel transfer an array of extents in a single file to a list of
buffers and vice-versa.  This call should be executed with read-ahead
disabled, it will usually be made when the user is well informed of the I/O
that is about to take place.

Is this easy to get into the Lustre client (using our I/O library)?  Do you
have this already for MPI/IO use?

Thanks.

Peter
