How many streams? Maximum number of streams

Hi,

is there a limitation on how many streams I can use in an application?
If I increase the number of streams in the simpleStreams example from the Cuda SDK to 256, the test fails.

I want to use several hundreds of streams in my application. Is that possible? And how expensive is stream creation?

Thanks in advance.

I’m curious about this too. Anyone with working experience on this?
