asyncEngineCount equivalent in Driver API?

Hi!

According to the Programming Guide for CUDA 4.0 there is the Runtime-API Device-Property “asyncEngineCount”, which can be 1 or 2, depending on the device’s capabilities (Sections 3.2.5.2 ff).

I’m using the Driver API and would like to query this capability. How can I do this?
cuDeviceGetAttribute() seems not to have what I’m looking for.

Thanks for any help!

Best greetings,

It does, see this constant:

CU_DEVICE_ATTRIBUTE_ASYNC_ENGINE_COUNT

Oh!

It’s not documented in the cuDeviceGetAttribute-specification of the Reference Manual, so I didn’t see it.
But it’s documented in the enums.

So, thanks a lot! :)

Best greetings,
Vogi
