EINSTEIN@HOME - Team FreeBSD
A team dedicated to the users of FreeBSD running BOINC under linux compatibility mode, or a native FreeBSD BOINC build. Team FreeBSD is dedicated to users of FreeBSD, but not limited to JUST the users. Anyone with the interest in developing a community of people interested in technology, open standards, NIX or BSD based operating systems are welcome and encouraged to earn credits and share ideas and conversation.

Interesting and Important WU Data Information...

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.

System Down Announcements, as of January 7th 2006

January 7, 2006
The Einstein@Home project was down for the last few days because of the continuing fileserver problems. Another server has been put in place for the primary fileserver and we hope this temporary solution will be stable.

The Einstein@Home project was down for the last couple days as a result of fileserver problems. The main fileserver has temporarily been replaced and we are hopeful the project will be more stable now.

The Einstein@Home project was down for the last day as a result of fileserver problems. The project should be totally back online by 18:00 UTC Dec 29.

The Einstein@Home project has been having database problems over the last two weeks. Your client will likely continue to have problems connecting to E@H until the problems are sorted out on our end. We are working on the problem and will try to have it solved as soon as possible.

Einstein@Home Beta Testing - FreeBSD HOWTO
25 August, 2006 18:05
This documentation was re-distributed from this source:
http://einstein.phys.uwm.edu/app_test.php
FreeBSD x86
The key features of this beta test App include:
- Assembler-coded "hot loop", on SSE machines, being faster while still keeping enough precision
- Tuned sin/cos calculations should give a small speedup on non-SSE-machines, too
- allows to process work for S5R1 as well as for old S4 Workunits
- Built on FreeBSD 5.5
- Sorry - No graphics
Installation instructions:
- If you are not running FreeBSD 5.x, make sure your kernel has COMPAT_FREEBSD5 enabled (which is the default) and you have installed misc/compat5x (ports)
- Stop any BOINC clients you have that may be running at this time.
- Download the following file:
- einstein_S5R1_4.09_i386-unknown-freebsd.tar.gz
md5sum: 1fbad1ff9d4fac45b45dd1e91a378173
- einstein_S5R1_4.09_i386-unknown-freebsd.tar.gz
- Locate the BOINC directory. If you use the boinc client from the ports collection, this will be
"/var/db/boinc/". Create it if needed.
Expand the archive you just downloaded into there. This will create subdirectories "projects/einstein.phys.uwm.edu" and add two files there. - Start the BOINC client (again), attaching to the einstein project if necessary.
You should see a message saying "Found app_info.xml; using anonymous platform". - Keep a close eye on the results of the application.
- Please report any problems you may have or success using this test version on
this thread.
We encourage beta testers to subscribe to this thread as new versions of the application will be announced there.
This App has the possibility to manually override the automatic CPU detection. If you see the App getting an illegal instruction signal, please report the problem in the forum thread and create a file named "CPU_TYPE_0" in your BOINC directory. This will force the App to use the generic code instead of the SSE one.

For those of you wondering what the EINSTEIN@HOME Project is:
Einstein@Home is a program that uses your computer's idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO gravitational wave detector. It also searches for radio pulsars in binary systems, using data from the Arecibo Observatory in Puerto Rico. Einstein@Home is a World Year of Physics 2005 and an International Year of Astronomy 2009 project supported by the American Physical Society (APS) and by a number of international organizations.My name is Andy Wright - the founder, but really the creator of Team FreeBSD. If you want me to add any links, or have any questions or inclinations for such things related to our group (or to just say hi) - send me an e-mail: einstein@extracted.org or Skype name: extracted
