Methods showsPrec :: Int -> Event -> ShowS # show :: Event -> String # showList :: [Event] -> ShowS #

data EventFlag Source #

Event creation flags

create :: [EventFlag] -> IO Event Source #

Create a new event

destroy :: Event -> IO () Source #

Destroy an event

http://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__EVENT.html#group__CUDA__EVENT_1g593ec73a8ec5a5fc031311d3e4dca1ef

elapsedTime :: Event -> Event -> IO Float Source #

Determine the elapsed time (in milliseconds) between two events

http://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__EVENT.html#group__CUDA__EVENT_1gdfb1178807353bbcaa9e245da497cf97

query :: Event -> IO Bool Source #

Determines if a event has actually been recorded

http://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__EVENT.html#group__CUDA__EVENT_1g6f0704d755066b0ee705749ae911deef

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.

http://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__EVENT.html#group__CUDA__EVENT_1g95424d3be52c4eb95d83861b70fb89d1

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.

block :: Event -> IO () Source #

Wait until the event has been recorded
