Workflow system 6.1.1 released

[Bernd Schuller]

Dear all,

I'm pleased to announce the availability of the 6.1.1 release
of the UNICORE workflow system, developed in the European
Chemomentum project (http://www.chemomentum.org)

It can be downloaded from http://www.unicore.eu/download

This release is based on UNICORE 6.1.1, and brings several bugfixes
and new workflow engine features. These include support for
conditional and loop constructs using user-defined variables,
file existence tests, and job exit code checks.

The workflow system can be used from the Eclipse client and
from the UCC (with workflow extensions).

Similar to the UNICORE 6 quickstart package, there is a tar.gz and a
jar file. Please refer to the file docs/setup.txt for information on
how to integrate with an existing UNICORE installation.

To update from the previous release, you should replace the jar files,
stop, delete the persistence data of the workflow engine, and restart.

Please note that this is work done in an ongoing project,
so the software is still under fairly heavy development. Also, the source
code is not yet in the usual UNICORE Subversion repository.
Documentation is also still a bit scant, sorry about that, but this
will improve in the near future.


Many thanks to all who helped build and test this release!

Best regards,
Bernd.
