January 11, 2006: Happy new year
- We moved to a much faster wiki at http://wiki.cogkit.org
- Refernces have been updated on Gregors homepage at http://www.mcs.anl.gov/~gregor
- Several significant enhancements to karajan have been made so that at this time we do recommend using the CVS version and not the release version.
- We expect a release at the end of January.
- Most of the guides are now completely in the wiki and no longer in LaTeX. This should simplify the maintenance and the community could help improving the guides.
- Accounts on the wiki have to be requested through e-mail to gregor@mcs.anl.gov. Unfortunately spammers abused our wiki.

May, 2005: Mike Sosonkin wins the Myron M. Rosentahl award
We like to congratulate Mike Sosonkin for winning the Myron M. Rosentahl award at Polytechnic, NY. An annual award established by Professor Myron M. Rosenthal for the best senior project in computer science at Polytechnic NY. Mike has performed exemplary and made the project he worked on over the summer to his senior thesis. He put a lot of additional effort in the project, which were obviously rewarded. His topic was the development of a certificate authority for Grids.
May 13, 2005: Java CoG Kit Workflow presentation at TACC
A presentation about the Java CoG Kit workflow was given at TACC by Gregor von Laszewski.
April 30, 2005: Status of CoG Kit Port to the Globus Toolkit 4
Now that the final version of the Globus Toolkit 4 is released and no major changes are expected, we will start our port to GT4.0.0 next week. As we have done several ports to pre-releases this should not take too much time. We will announce our alpha port to this release as soon as we have it available.
The upcoming Java CoG Kit GT4.1a will also include enhancements to the file abstractions, the workflow specification language and the workflow engine. We will also introduce major enhancements to our GridShell. As pointed out on the mailinglist we have also replaced the classes that included the word "core" in the package name to avoid confusion with the term core used in GT4.
April 30, 2005: CoG Kit Contributions to Globus Toolkit 4
We are happy to report that the Java CoG Kit group has contributed to the development of the Globus Toolkit 4 by providing the following:
- the Java CoG Kit jglobus module that is known under cog-jglobus.jar which includes the GridFTP Java client libraries, the GSI libraries developed in conjunction with the GT4 team, the client interfaces to old style Globus Toolkit services
We also conducted extensive tests of using prereleases of GT4. Additionally the Java CoG Kit group also helped in the development of the Grid Usage Sensor Service as used by WS-GRAM and GridFTP and other services.
What is not distributed? The Java CoG Kit contains two major frameworks that are not distributed with the current version of GT4 but provide significant add on features. This includes our _abstraction model_ that makes it technically possible to develop Grid programs that can run on GT2, GT3, or GT4. It also includes the availability of a _workflow framework_ for Grids that allows you to utilize workflows without having to write Java programs. Besides this, the setup component of Java CoG Kit 4 may be of interest to many as it is an enhancement of what is included in jglobus.
April 30, 2005: Globus Toolkit 4 Web site: Where is the CoG Kit link?
The Globus Toolkit 4 has been released and the web site has been restructured. We were made aware by some in the community that the link to the CoG Kit is now more difficult to find. Therefore, we like to make you aware that besides the link http://www.globus.org/cog you can simply go to http://www.cogkit.org. This allows us to maintain all our Web pages to be maintained through a wiki. We invite the community to make suggestions to the improvement of these pages. We are working with the GT4 web designers to add more prominent links for the Java CoG Kit.
April 29, 2005: Java CoG Kit Abstractions demonstrated by IBM project
The Java CoG Kit abstractions have been proven useful to IBM. An article about this can be found at http://www-128.ibm.com/developerworks/library/gr-ogce/. Note that the classes have been modified recently. We have in Java CoG Kit 4 more advanced file abstractions. We also have replaced the word "core" with "abstractions" to avoid confusion with the use of word core in GT4.
April 25, 2005: FAQ
We have started to collect some Frequent Asked Questions and hope the community will help us adding questions and answers. At present we allow the community to add information to the FAQ. The link can be found at http://www.cogkit.org/w/index.php/FAQ
April 10, 2005: Simplification of the Web pages
We have simplified the design of the Web pages and now exclusively use our Wiki to maintain them.

Award: CoG Kits receive best research Poster Award at SC2004
Among 109 other entrants the Java CoG Kit team under leadership of Dr. Gregor von Laszewski (the co-PI of the REU) won the best research poster award at the Supercomputing 2004 conference in Pittsburgh in November. The poster, "The Next Generation of the Java CoG Kit," summarized a multi-year research effort conducted Argonne National Laboratory and the Computation Institute at University of Chicago, in making Grid computing more easily accessible. In order to integrate Grid computing into a researcher’s portfolio of tools, the Java CoG Kit provides a useful step in this direction.
