Making OpenCL? Simple with Haskell - AMD Developer Central

SYNCHRONIZATION: QUEUES & EVENTS
Each individual queue can execute in-order or out-of-order
– For in-order queue, all commands execute in order
You must explicitly synchronize between queues
– Multiple devices each have their own queue
– Multiple queues per device
– Use events to synchronize
Events
– Commands return events and obey waitlists
– clEnqueue*(. . . , num_events_in_waitlist, *event_waitlist, *event);
