Hi Murali,
I just ran IOR using a server using ramfs (output below).
I searched the pvfs2 lists for existing IOR scripts and the only
thing I found was the mpi-io scripts. I will test those next, but I
was wondering if you had other IOR scripts in mind.

Hi Scott,
Excellent!! Very cool stuff!
Can you also run connectathon, ior and/or ltp?
There must be email archives on the -dev list for cmnd line options to
run them..
thanks!

Hi all,
The code is complete as far as features go. I am using the gossip
library for all output. I can use the command line tools and the
kernel module works as well.
I have tested the server by killing clients during long transfers and
the clients can reconnect correctly and continue with new operations.
I have killed the server while the client has mounted the kernel
module, and when I restart the server, the client can start new
operations.
I have only briefly looked at the $PVFS2/test/io/bmi suite. I will
try to run these next.
Are there any other suggested tests? Should I try to run the full
$PVFS2/test suite? What is recommended?
I will test on older hardware first. After I am familiar with the
tests, I will then switch to some 10G machines.
Thanks,
Scott
