Read Me

This is a test program which simulates multiple separate NFS clients
from a single client machine.  It uses IP aliases and userspace
RPC client code to send NFS traffic that appears to come from
multiple hosts.  It also includes feedback-controlled call rate code
which generates very steady call rates from each simulated client;
this allows the IOPS and Throughput numbers in nasmgr's per-client
stats pages to be tested.  

The workload is currently only looping streaming reads using 32KiB
rsize one file per simulated client.  A PRNG based on the digits of
PI sets the relative weights of each simulated client to different
values, and a total throughput of 10MB/s (decimal megabytes not binary
mebibytes) is divided between clients according to that weighting.
The expected call rate and throughput for each client is printed
during startup.

To use:

1. build and copy the "weber" executable to the client machine.

2. ensure the server has an exported directory /server

3. ensure the server has in /server files called read.N for
   N=0 to however many simulated clients you want.  These should
   each be a multiple of 32KiB long.  Actual size doesn't matter,
   but small files can live entirely in the server's RAM.  I use
   1MiB files.

4. run weber.  Arguments are: server, number of simulated clients,
   protocol.  The server should be on the 192.168.42/24 subnet (and
   have it's last octet greater than the number of simulated clients
   you plan to use)

   # ./weber shake-g42 32 tcp

Creating local IP aliases is inherently very OS-specific.  Currently
the code only knows how to do so for IRIX.

Note, the test.melbourne.sgi.com network has DNS entries for
all the addresses in 192.168.42/24, called "fakeN-g42".
