ABSTRACT:: 
STARFISH is a parallel file-system simulator we built for our research
into the concept of disk-directed I/O.  In this report, we detail
steps taken to tune the file systems supported by STARFISH, which
include a traditional parallel file system (with caching) and a
disk-directed I/O system.  In particular, we now support two-phase
I/O, use smarter disk scheduling, increased the maximum number of
outstanding requests that a compute processor may make to each disk,
and added gather/scatter block transfer.  We also present results of
the experiments driving the tuning effort.
