The Command Queue

The package CL.Command_Queues

To execute your kernels, you have to enqueue them in a command queue. You can create a command queue for the target device by providing a context created for that device. With this command queue, you can execute all kernels an access all memory object linked to this context.

The package CL.Queueing

Enqueueing tasks can be done with the functions in CL.Queueing and its child package CL.Queueing.Memory_Objects. The base package can execute a kernel in data-parallel mode (as kernel) or only once (as task). The child package can enqueue actions to transfer memory objects from and to OpenCL memory.

The package CL.Events

For synchronization between kernels and tasks executed by the command queue, you can use the Event type. Each instance of these type signals whether the action it is linked to has already been finished.
