Fri, 25 Dec 2009 23:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#134 http://spin.fh-bielefeld.de/all_news.php#134 Wir wünschen allen Teilnehmern und ihren Familien schönes Weihnachten und ein gutes Jahr 2010. Vielen Dank für die großartige Unterstüzung in 2009. We wish all participants and their families a Merry Christmas and a good 2010. Thanks for the great support in 2009. Wed, 23 Dec 2009 23:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#133 http://spin.fh-bielefeld.de/all_news.php#133 Some update of the very long term of the Fe30 series and others: The first basic question behind these (enormous!!!) calculations is whether these molecule exhibits so-called spin glass behaviour or not and what is the origin of that. Spin glasses are still a very hot topic in general physics but until now it has been only observed in large three dimensional bulk systems. If Fe30 would show spin glass behaviour we would have the first ZERO dimensional spin glass (just 30 spins on a sphere!) in history! The second basic question addresses the stability of the chemical synthesis process of Fe30: To what extend is the synthesis process stable, i.e. produces exactly the same kind of structure in each run? Until know it has been stated that there is no variation at all. However, a couple of month ago a group of chemists has presented a different kind of Fe30. Regarding applications we just got a grant from the German Research Foundation in Bielefeld where on of the scopes is to put these molecules on surfaces and study the modified magnetism. Here we hope to find some interesting effect . however, nobody can tell yet! After that project we have plans for several different projects. We have created a new client which will be released soon for so-called Quantum Monte Carlo calculations. With these calculations we can study quantum effects in the molecules in great detail (please be patient for further details soon!). Another project in our pipeline deals with the extension of the client in order to calculate dynamical response functions. These properties start to become important in the magnetic molecule community in order to study dynamical effects, i.e. the reaction of a molecule to a time varying magnet field. Such effects can answer many basic questions but also can help to answer the question for the usefulness of a special molecule for magnetic memory devices.

The work on electrical installation were finished over this week. Have a sunny weekend. Thu, 25 Jun 2009 22:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#131 http://spin.fh-bielefeld.de/all_news.php#131 Wir werden vom 19.06.09 ab 17:00 Uhr bis zum 22.06.09 9:00 Uhr und vom 26.06.09 ab 17:00 Uhr bis zum 29.06.09 9:00 Uhr offline sein. Es werden Arbeiten an der elektrischen Anlage an unserem Standort Wilhelm-Bertelsmann-Strasse in diesem Zeitraum durchgeführt. Ich bitte um Verständnis. Vielen Dank. We are from 19.06.09 from 17:00 clock until 22.06.09 9:00 clock and from 26.06.09 from 17:00 clock to 29.06.09 9:00 clock offline. There will be work on the electrical installation at our campus Wilhelm-Bertelsmann-Strasse in this period. I ask for your understanding. Thank you very much.

The compressor had a defect. 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! Regards Thomas Sun, 24 May 2009 22:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#129 http://spin.fh-bielefeld.de/all_news.php#129 We have reduced the scheduler contact time from 20 to 15 minutes. If this is also too long please give a hint in our forum. Sun, 26 Apr 2009 22:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#128 http://spin.fh-bielefeld.de/all_news.php#128 A short server outage over the weekend because of problems with our university network. Now all should work again. It could be that the validator state on server-status-page is shown as "Not Running" because it crashes when a workunit hasn't the flag for static credits. But the WUs with these flags are rarely. Mon, 12 Jan 2009 23:00:00 GMT http://spin.fh-bielefeld.de/all_news.php#127 http://spin.fh-bielefeld.de/all_news.php#127 We start a new series of the Fe30 Map Workunits. Prof. Dr. Schroeder is working on a new algorithm for Spinhenge@home and 2 of our students are working hard on an optimization of the linux client and on a 64 bit version. The first results seem very good. Sun, 14 Dec 2008 23:00:00 GMT
