= Non-CPU-intensive applications =

A 'non-CPU-intensive' project is one whose applications use little CPU time. Examples include:

 * Host measurements
 * Network measurements
 * Web crawling
 * Network data access

A non-CPU-intensive project is treated specially by the core client:

 * The core client maintains one result for the project
 * The core client executes this result whenever computation is enabled,     bypassing the normal CPU scheduling mechanism.

A project labels itself as non-CPU-intensive by including the `<non_cpu_intensive>` flag in its [ProjectConfigFile configuration file]

This attribute is at the project level; there is no provision for a project to have some applications that are CPU intensive and some that aren't.

Non-CPU-intensive applications can use chunks CPU time; this won't break anything, and the CPU scheduler will adjust to it by changing its estimates of 'CPU efficiency'. However, non-CPU-intensive applications should try not to use more CPU time than their resource share fraction indicates.
