This is the first WPVM version with fixed bugs. As you can see, there are few fixed bugs because I have received
few bug reports: I hope that means WPVM is stable, and ready to be used intensively.
In the last weeks WPVM (32 bits) have been intensively tested with NAS benchmarks and it behaves very good.
With 'very good' I mean is error free and very interesting performance results.

SUMMARY
---------
WPVM (Windows Parallel Virtual Machine) is a software package that permits a heterogeneous
collection of MS Windows computers hooked together by a network to be used as a single large 
parallel computer. 
WPVM is based on the original PVM package (version 3.3.0) from the Oak ridge National Laboratory.
WPVM machines can coexist in a virtual machine with UNIX computers running the Oak Ridge 
original PVM.


OFFICIAL WEB SITE

COPYRIGHT NOTICE

Using and distributing WPVM:
WPVM may not be used for commercial or industrial purposes without a prior license agreement 
with the author.
Beside that, WPVM may be used for any other purposes at no cost. In may be 
distributed by any means, provided that the original files as supplied by the author remain 
intact and no charge is made other than for reasonable distribution costs.
You do not need to register or buy a license in order to use WPVM for non-commercial uses.
WPVM may be made available on any archive or BBS system, although I would appreciate people 
to fill in the form with general data, before download it from the official Web site.
This is very important  to me in order I can gain insight on what kind of people/organizations 
are interested in using the package.


FIXED BUGS:
------------

1- Now you can spawn locally, (in each host), more than 10 processes. (actually you are limited to ~45)
2- When the virtual machine lost connection with one host, master and slave daemons behave now in a stable way.
3- Some small interface problems are now fixed.

WPVM PROBLEMS:
--------------
However people have successfuly run the WPVM daemon in NT workstations, it does not run in NT server.
Nevertheless, WPVM runs ok in other MS Windows 32 bits environments. 
In future releases, when I have a 32 bit debugger, that bug will be fixed.
For now, if you want to play with WPVM on NT, you can try 16 bits version: It runs well in that environment.
