Project News - Einstein@Home
« on: March 25, 2009, 08:47:25 PM »

From Einstein News Archive:

25 Mar 09:

The Einstein@Home project has started a new search for binary radio pulsars in data from the Arecibo Observatory in Puerto Rico. This will run in parallel with the existing search for gravitational waves from rapidly-spinning neutron stars.

Too bad Einstein server has crapped itself for the past few days

From Einstein News Archive 23 Apr 09:

The database is still purging, at a rate of about 400,000 workunits per day. We expect that
this process will be completed by about 06:00 UTC tomorrow. At that time, we will do some additional
database maintenance (table optimization) and then restart the project. So in total about another 24
hours will still be needed to bring everything back to normal. Thanks again for your patience during
this unfortunate and long outage.

The Einstein@Home project is finally back up and running properly. The binary radio pulsar
search may not be sending out new work for a couple of more days while we fix some VPN
problems between the WU generator in Hannover and the project database in Milwaukee.
However the S5R5 gravitational-wave search IS sending out plenty of work.
Many thanks again to our loyal volunteers and contributors for their patience!

Over the weekend the VPN problems were fixed, so the Arecibo Binary Radio Pulsar search
is now also running correctly and sending out new work. So Einstein@Home has completely recovered and is
back in full operation again!

Confused by curved spaces? baffled by black holes? than you are ready for Einstein@ Home.
Einstein@Home uses computertime donated by people like us all over the world.
I thought you might like to watch a related short video about black holes click here.  It is a facinating subject.

Webpages describing the new Einstein@Home search for binary pulsars in Arecibo radio data are online now. Follow this link to learn more about radio pulsars, how our new search works, and how it can help us searching for gravitational waves.

Einstein@Home is down as the result of a fileserver crash.  I am working on repairing
the filesystem now but I do not have an estimate of how long this could take yet.  
Further news will be posted here when we know more.

Thank you for your patience.

To date, the ongoing Einstein@Home search for binary pulsars in Arecibo radio data has re-discovered a number of known pulsars.  Interested users can find some information about these on the (re-)discoveries page. More information about the radio pulsar search may be found on this page.

Our main focus now is to try and speed up the application. E@H is currently processing about 18 minutes of Arecibo data per day. We think that, via various tricks, improvements, optimizations, and GPU-enablings, we can increase this processing speed by almost an order of magnitude, to about 2 hours/day. This would enable us to catch up on the PALFA data set (which on average is about an hour of data per day). Hopefully we can get many of these improvements working this summer and fall.

Tuesday, 4 August 2009 10:00 AM

The Einstein@Home search for binary pulsars in Arecibo radio data has re-discovered four more known pulsars.
More information on these re-discoveries and four re-observations of pulsar J1903+0327 can be found on the (re-)discoveries page. For information on the binary radio pulsar search please have a look at this page.

Einstein@Home is down as the result of yet another fileserver crash.  We are
working on repairing the filesystem now but it will likely take a couple days
before the project is running again.  Further news will be posted here.

Thank you for your patience.

The first attempt to fix the filesystem failed and the second attempt is
underway.  We will have more news in about 36 hours.

Today's latest from Einstien@Home and the recovery from the File Server Crash:

Quote
Sun Aug 16 12:47:54 UTC 2009

The filesystem repair is finally moving forward as hoped.  Step one is complete
and step two should finish in about 7 hours.  If everything works out we should
be able to start bringing the project back online at that time.

Thank you again for your patience.
