The new "Albert" search application seems to be working very well, so we are beginning to distribute thousands of "Albert" workunits. For more information, please see the this thread, http://einstein.phys.uwm.edu/forum_thread.php?id=3431 , in the message boards. Happy holidays!!

December 23, 2005
After almost five months of development and private testing, Einstein@Home will begin public testing and distribution of a new search application called "Albert". This is an improved and more sensitive version of the previous search code. Initially we will send out only a few hundred workunits for this new search, but if these are successful, we will begin broader distribution of these new workunits over the coming few days. If unexpected problems arise, please be patient, and look in the Problems and Bug Reports, http://einstein.phys.uwm.edu/forum_forum.php?id=6 , message board for additional information.

A report on the final results of the Einstein@Home S3 search may be found in a talk given by Bruce Allen on behalf of the LIGO Scientific Collaboration, http://www.phys.utb.edu/GWDAW10/other/f ... eAllen.pdf , at the 10th annual Gravitational Wave Data Analysis Workshop.

Einstein@Home is now distributing an experimental application for Solaris (on SPARC). This has no graphics yet, but we hope to have a graphical version ready soon. Please report problems or success on this message board thread http://einstein.phys.uwm.edu/forum_thread.php?id=2722 .

Einstein@Home has begun processing of a small number of test workunits using data from the LIGO S5 science run. This is the first LIGO data collected at the instrument's design sensitivity. We'll post more information in the 'Cruncher's corner' message board area, http://einstein.phys.uwm.edu/forum_forum.php?id=3 , as we begin to create more of these workunits.

We are beginning large-scale distribution of workunits from LIGO and GEO's fifth science run S5. We have finished generating the remaining S4 workunits, and expect that the processing of these S4 workunits will be completed during the next two to three weeks.

June 16, 2006
Einstein@Home will be shutdown for a few hours starting at 08:00 on Jun 16 UTC: we are adding a new file server.

A couple of days ago Einstein@Home issued the last workunits from our first search of LIGO S5 data. The post-processing of these results will begin in a few weeks when the last result from these workunits is returned. Meanwhile we are gearing up to begin a new type of more sensitive search (called a hierarchical search). Unfortunately this is not yet ready. In the meantime we are extending the first S5 search to a larger range of spin-down ages than previously. We apologize for some problems that occured in the last few days as we finished one search and started another. We are still coping with some hardware problems, which complicated the transition. For further details please see this message board thread: http://einstein.phys.uwm.edu/forum_thread.php?id=5304

We have started a new analysis run on LIGO S5 data, called S5R3. This uses a new version of the science application - details will be forthcoming in the Science Message Board area. Users who have been beta-testing the latest app versions should now remove their app_info.xml files.

A description of the latest S5R3 search, and the sensitivity improvements that it gives compared with earlier versions of the Einstein@Home search, is described in this message board thread, http://einstein.phys.uwm.edu/forum_thread.php?id=6193 .

Oct 2, 2007
The S5 science run, whose goal was to accumulate one year of triple-coincident data at LIGO design sensitivity, officially ended at 00:00 UTC October 1, 2007. This completes the data-taking stage of a project which was officially begun in 1992 by Kip Thorne, Ron Drever, and Rainer Weiss. LIGO will now undergo two planned upgrades to improve sensitivity. The first of these upgrades (Enhanced LIGO), http://www.ligo.caltech.edu/docs/T/T060156-01.pdf , will be followed by the S6 science run, anticipated for 2009, http://www.ligo.caltech.edu/docs/G/G070 ... 542-00.pdf . Einstein@Home is now busy searching the S5 data set. The Einstein@Home S4 postprocessing and analysis are largely complete and under review by the LIGO Scientific Collaboration. We hope to provide updates about these results before the end of this year.

The E@H project will be down until a problem with the database is fixed. We expect all the problems to be worked out by Mon Oct 15 21:00 UTC.

The E@H project will be down until a problem with the database is fixed. This is taking a bit longer than expected. We expect all the problems to be worked out by Mon Oct 15 23:00 UTC.

The database problems have been fixed, and the Einstein@Home project is up and running again. Please note that a few contributors may notice some of their results in a strange or incorrect state. Please see this message board thread for more details and to report any problems.
