# simple_partitioner Class¶

## Summary¶

Specify that a parallel loop should recursively split its range until it cannot be subdivided further.

## Syntax¶

class simple_partitioner;


## Description¶

A simple_partitioner specifies that a loop template should recursively divide its range until for each subrange r, the condition !r.is_divisible() holds. This is the default behavior of the loop templates that take a range argument.

Tip

When using simple_partitioner and a blocked_range for a parallel loop, be careful to specify an appropriate grain size for the blocked_range. The default grain size is 1, which may make the subranges much too small for efficient execution.
