<h3>Status</h3>
</center>
<p>
BOINC is under development.
The <a href=source/>source code</a> is available.
We are currently conducting a beta test of BOINC
using the <a href=http://setiathome.berkeley.edu>SETI@home</a> and
<a href=http://maggie.ssl.berkeley.edu/ap/>Astropulse</a> applications
(thanks, but we don't need more beta testers at this point).
The public release will be announced on the
<a href=http://setiathome.berkeley.edu>SETI@home</a> web site.
Several other distributed computing projects are evaluating BOINC.

<b>October 18, 2003</b>
<br>
A SETI@home application has been added to the beta test.
The scheduling server detect results that can't be sent
to any hosts, and flags them.
HTTP 404 errors on downloads are treated as unrecoverable.
Graphics can be limited by frame rate or percent of CPU.
Don't send two results from the same workunit to a single user.
Added JPEG support to application graphics.
Added "confirm before accept executable" mechanism.

BOINC is discussed in
<a href=http://www.nytimes.com/2003/09/11/technology/circuits/11dist.html>
an article by Joan Oleck in the New York TImes</a>.
<br><br>
<b>September 4, 2003</b>
<br>
We've released BOINC version 2.0.
All BOINC components must be upgraded to major version 2.
We've upgraded the <a
href=http://maggie.ssl.Berkeley.edu/ap/>Astropulse</a> server to 2.01 and
released <a href=http://setiboinc.ssl.Berkeley.edu/ap/download.php>BOINC core
client 2.01</a>.
This was due to an architecture and protocol change in
specifying resource estimates and limits.
<br><br>
<b>September 1, 2003</b>
<br>
BOINC server tools are now Python-based. A <a href=python.php>database
back-end API</a> allows quick development of data-manipulation utilities.
<br><br>
<b>August 15, 2003</b>
<br>
We rewrote parts of the scheduling server architecture to make operations
more flexible and efficient. The <code>timeout_check</code>
daemon has been replaced by a more general <code>transitioner</code> daemon.
