specify depth of channel

Hi,

I found some information about channel depth in the programming guide.

Implementing Buffered Channels Using the depth Channels Attribute

You may have buffered or unbuffered channels in your kernel program. If there are imbalances in channel

read and write operations, create buffered channels to prevent kernel stalls by including the

depth

attribute in your channel declaration. Buffered channels decouple the operation of concurrent work-items

executing in different kernels

Here is an example:

channel int c __attribute__((depth(10)));
