<h2>Getting started</h2>
|
|
It's easy to participate in ".PROJECT."
|
|
<ul>
|
|
<li> <b>Create an account.</b>
|
|
Go to the <a href=create_account_form.php>Create account</a> page
|
|
and fill out the form.
|
|
You will receive an email containing
|
|
your <b>account ID</b> (a long random string).
|
|
Save this email.
|
|
<li> <b>Download and install BOINC.</b>
|
|
Go to the <a href=http://boinc.berkeley.edu/download.php>download page</a>,
|
|
download the BOINC software for your type of computer,
|
|
install it, and run it.
|
|
You will be asked to enter the project URL
|
|
(".MASTER_URL.") and your account ID.
|
|
</ul>
|
|
That's it!

<h2>How it works</h2>
|
|
When you run BOINC on your PC,
|
|
it works as follows (see below):
|
|
<br>

|
<img hspace=10 vspace=8 src=http://boinc.berkeley.edu/comm_simple.png>
|
|
</center>
|
|
<br>
|
|
<ol>
|
|
<li> Your PC gets a list of instructions from the project's
|
|
<b>scheduling server</b>.
|
|
The instructions depend on your PC: for example,
|
|
the server won't give it work that requires more RAM than you have.
|
|
The instructions may include many separate pieces of work.
|
|
Projects can support several <b>applications</b>,
|
|
and the server may send you work from any of them.
|
|
<li> Your PC downloads executable and input files
|
|
from the project's <b>data server</b>.
|
|
If the project releases new versions of its applications,
|
|
the executable files are downloaded automatically to your PC.
|
|
<li> Your PC runs the application programs, producing output files.
|
|
<li> Your PC uploads the output files to the data server.
|
|
<li> Your PC reports the completed results to the scheduling server,
|
|
and gets instructions for more work.
|
|
This cycle is repeated indefinitely.
|
|
</ol>
|
|
BOINC does this all automatically;
|
|
you don't have to do anything.

<h2>Credit</h2>
|
|
The project's server keeps track of how much work
|
|
each participant has contributed;
|
|
this is called <b>credit</b>.
|
|
The following system is used
|
|
to ensure that credit is granted fairly:
|
|
<ul>
|
|
<li> Each work unit is sent to at least two computers.
|
|
<li> When a computer reports a result,
|
|
it claims a certain amount of credit,
|
|
based on how much CPU time was used.
|
|
<li> When at least two results have been returned,
|
|
the server compares them.
|
|
If the results agree, then users are granted
|
|
the smaller of the claimed credits.
|
|
</ul>

|
|
<center>
|
|
<img src=http://boinc.berkeley.edu/credit.png>
|
|
</center>
|
|
<br>
|
|
There may be a delay of several days between
|
|
when your computer reports a result
|
|
and when it is granted credit for the result.
|
|
Your <a href=home.php>User page</a> shows you how much credit is 'pending'
|
|
(claimed but not granted).
