<h2>Core client: file structure</h2>
|
|
<p>
|
|
The core client runs in a <b>BOINC home directory</b>.
|
|
It creates and uses the following files and directories within the
|
|
home directory:
|
|
<ul>
|
|
<li>
|
|
<b>prefs.xml</b>:
|
|
The user's global preferences; see below.
|
|
<li>
|
|
<b>client_state.xml</b> describes of the files,
|
|
application, workunits and results present on this client.
|
|
<li>
|
|
<b>Account files</b> describes the participant's account
|
|
in each subscribed project,
|
|
including the resource share and project-specific preferences.
|
|
It contains no host-specific information.
|
|
The name of the account file is <b>account_PROJECT.xml</b>,
|
|
where PROJECT is an encoded version of the project's master URL.
|
|
<li>
|
|
A directory <b>projects</b>,
|
|
which contains a <b>project directory</b> for each subscribed project.
|
|
The name of a project directory is an encoded
|
|
version of the project's master URL.
|
|
The project directory contains all files (inputs,
|
|
outputs, executables) related to the project.
|
|
<li>
|
|
<b>slots</b>: this directory contains one subdirectory for each
|
|
CPU "slot" (normally there are as many slots as the host has CPUs).
|
|
The subdirectories are named 0, 1, ... N-1.
|
|
</ul>
|
|
<p>
|
|
Each result executes in particular slot directory.
|
|
The core client creates "soft link" files in the slot directory,
|
|
linking to the corresponding files in the project directory.
|
|
|
|
<h3>Format of account files</h3>
|
|
The format of an account file is as follows:
|
|

|

|
|

</account>
|

|
|

|
|
