Thomas has become the successor of Mr. Hartmann and manages now the labs "Compuattional Science Lab" and "Technical Computer Science". This was and is a lot of work and therefore Spinhenge@home came a little bit too short. Second, the forum is now back online. It can be reached here. Third, we are currently reorganizing our software architecture for the client application which unfortunately takes much more time than planned. One thing is that we want to merge all input information in just one compact file, so that we can save space and time on your computers. Also, we are implementing several new functions. Most important for us now is a new method that allows us to simulate a magnetic nano system which is subject to a time dependent magnetic field. With this we are able to calculate the so-called AC susceptibility for a system which gives us information about its internal energy barriers. This property is vital for identifying so-called single molecular magnets (SMM). These SMM are candidates for future memory devices since they allow to store information in a much smaller space than conventional magnetic recording materials. The implementation of this method is not that easy and requires the numerical solution of stochastic differential equations which simulate the dynamics of the individual magnetic moments in a nano system. The first big chunk of this task is done and successfully tested (many thanks to Andrértmeier!). We hope to be able to do first test calculations using the new client application soon! Fourth, we are currently planning the reorganization of our server infrastructure. The three project server should run in the future in a virtual environment. Please keep fingers crossed! And thanks a lot for your patience!

We are working on it.

Vielen Dank für die großartige Unterstützung in 2011. The team of Spinhenge wish all participants and their families a good 2012. Thanks for the great support in 2011. Best regards The Spinhenge team Tue, 27 Dec 2011 23:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#155 http://spin.fh-bielefeld.de/all_news.php#155 We have had a hard server crash of database server. The spare parts have been built in. After it was repaired I have had to rebuild the database. Now all should work again. If you have trouble please post it on our forum (here). Were are back online now! We are very sorry for the long outage. Regards Thomas Tue, 22 Nov 2011 23:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#154 http://spin.fh-bielefeld.de/all_news.php#154 When the 04_core_shell_nanoparticles series is finished, we will pause Spinhenge@home for about three month. We plan to upgrade the server hardware, the client and the server hardware. We also need some time to evaluate the results of the last two series (the *fe30_map_*_* and the core_shell_nanoparticles). Updates about our progress will be post on the news and our forum. We thank all users for the great support!!!

The spare parts have been built in. After it was repaired I have had to check the database and the file server. Now all should work again. If you have trouble please post it on our forum (here). Were are back online now! We are very sorry for the long outage. Regards Thomas Mon, 06 Jun 2011 22:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#151 http://spin.fh-bielefeld.de/all_news.php#151 We realized that the statistical accuracy of the results is not yet sufficient and therefore need to run a second series of that kind. We are curious to see the results!

Wir werden dann das neue Projekt "core_shell_nanoparticle" verteilen. We will have a workunit downtime period approximately 5 days after the current series before we distribute new workunits. We will then distribute the new project "core_shell_nanoparticle". Fri, 08 Apr 2011 22:00:00 GMT
