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.

Einstein@Home Beta Testing - FreeBSD HOWTO

25 August, 2006 18:05 CST6CDT

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:

1. 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)
2. Stop any BOINC clients you have that may be running at this time.
3. Download the following file:
   • einstein_S5R1_4.09_i386-unknown-freebsd.tar.gz
     md5sum: 1fbad1ff9d4fac45b45dd1e91a378173
4. 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.
5. 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".
6. Keep a close eye on the results of the application.
7. 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.

BOINC survey

24 August, 2006 23:22 CST6CDT

Now would be a good time to take the BOINC survey and let the world know this application is widely used on other systems, not just Windows and Linux.

Here is what we have so far:

9926 Windows
886 Macintosh
1935 Linux
200 Other

Congratulations!

We have over a half a million credits, with around 3,000 credits for a recent average!

Congratulations to everyone whom are part of this team! Their are so many faithful leaders in this group that dedicate precious computer resources for this important project of science. All of you have put in a great deal of effort in advancing the investigation of the project's goals. We are a unique team indeed. The team name, ''FreeBSD'', may be specific in the sense of the name, though our relation to the team name is broad -such as our dedication is not name based-, rather it is a team open to various beliefs, many of them which are popular to the FreeBSD operating system community. I think we have all noticed, we are a very unique group of individuals. Congratulations to everyone! Lets hit a million!

For those of you wondering what the EINSTEIN@HOME Project is:

Einstein@Home uses your computer's idle time to search for weak astrophysical signals from spinning neutron stars (also called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite. Einstein@Home volunteers have already discovered more than a dozen new neutron stars, and we hope to find many more in the future. Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars. Gravitational waves were predicted by Albert Einstein almost a century ago, but have never been directly detected. Such observations would open up a new window on the universe, and usher in a new era in astronomy.

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

''It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure'' -- Albert Einstein
