Function Documentation

void WorkParallelForEach ( InputIterator  first,
InputIterator  last,
Fn &&  fn 
)
inline

WorkParallelForEach(Iterator first, Iterator last, CallbackType callback)

Callback must be of the form:

void LoopCallback(T elem);

where the type T is deduced from the type of the InputIterator template argument.

Definition at line 149 of file loops.h.

void WorkParallelForN ( size_t  n,
Fn &&  callback,
size_t  grainSize 
)

WorkParallelForN(size_t n, CallbackType callback, size_t grainSize = 1)

Runs callback in parallel over the range 0 to n.

Callback must be of the form:

void LoopCallback(size_t begin, size_t end);

grainSize specifices a minumum amount of work to be done per-thread. There is overhead to launching a thread (or task) and a typical guideline is that you want to have at least 10,000 instructions to count for the overhead of launching a thread.

void WorkParallelForN ( size_t  n,
Fn &&  callback 
)

WorkParallelForN(size_t n, CallbackType callback, size_t grainSize = 1)

Runs callback in parallel over the range 0 to n.

Callback must be of the form:

void LoopCallback(size_t begin, size_t end);

Definition at line 129 of file loops.h.

void WorkSerialForN ( size_t  n,
Fn &&  fn 
)

WorkSerialForN(size_t n, CallbackType callback)

A serial version of WorkParallelForN as a drop in replacement to selectively turn off multithreading for a single parallel loop for easier debugging.

Callback must be of the form:

void LoopCallback(size_t begin, size_t end);
