configured to
- Produce more detailed log messages.
These messages appear in the Messages tab of the BOINC Manager
(informational messages in black, error messages in red).
On Windows, they are written to a file (stdoutdae.txt).
On Unix, they are written to standard output.
- Control various behavioral parameters, such as how many
simultaneous file transfers to allow.
These options are useful primarily for testing and debugging.
The configuration is read from a file cc_config.xml.
If this file is absent, the default configuration is used.
This file has the following format:
".html_text("
[ flags ]
[ N ]
[ 0|1 ]
[ 0|1 ]
[ N ]
[ N ]
[ N ]
")."
For example, if you want to see messages about CPU scheduling,
use a text editor (such as Notepad) to create the following file,
and save it as cc_config.xml in your BOINC directory.
".html_text("
1
")."
Logging flags
The flags within <log_flags> are used to
selectively turn different types of messages on and off
(<tag>0</tag> for off, <tag>1</tag> for on):
The following messages are enabled by default:
";

"The start and completion of compute jobs
(should get two messages per job)."
