Description

Event management for low-level driver interface

Synopsis

Event Management

newtype Event Source #

Events are markers that can be inserted into the CUDA execution stream and later queried.

Constructors

Event 

Fields

Instances

Eq Event Source # 

Methods

(==) :: Event -> Event -> Bool #

(/=) :: Event -> Event -> Bool #

Show Event Source # 

Methods

showsPrec :: Int -> Event -> ShowS #

show :: Event -> String #

showList :: [Event] -> ShowS #

record :: Event -> Maybe Stream -> IO () Source #

Record an event once all operations in the current context (or optionally specified stream) have completed. This operation is asynchronous.

wait :: Event -> Maybe Stream -> [WaitFlag] -> IO () Source #

Makes all future work submitted to the (optional) stream wait until the given event reports completion before beginning execution. Synchronisation is performed on the device, including when the event and stream are from different device contexts.

Requires CUDA-3.2.
