Detailed Description

Function Documentation

template<typename TF >

void Grappa::privateTask

(

TF

tf

)

Spawn a task visible to this Core only.

The task is specified as a functor or lambda. If it is 24 bytes or less, it is copied directly into the task queue. If it is larger, a copy is allocated on the heap. This copy will be deallocated after the task completes.

Template Parameters

TF	type of task functor

Parameters

tf	functor the new task.

Example:

int data = 0;
Grappa::spawn( [&data] { data++; } );

Shove copy of functor into space used for task arguments.

Todo:

: misusing argument list. Is this okay?

// if not, substitute this:

template<typename TF >

void Grappa::publicTask

(

TF

tf

)

Spawn a task that may be stolen between cores.

The task is specified as a functor or lambda, and must be 24 bytes or less (currently).

See also

Grappa::spawn for usage.

void Grappa::spawn

(

TF

tf

)

Synchronizing private task spawn.

Overload.

Automatically enrolls task with GlobalCompletionEvent and does local complete when done (if GCE is non-null). In this version, GCE is a template parameter to avoid taking up space in the task's args.
