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.

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.
