I'm testing spmv sample in brook+. When I change NzWidth from 2 to 10, it's reporting "Failed to find usable kernel fragment to implement requested reduction". When the factor is 8, it's running correctly.

I find this thread (http://forums.amd.com/forum/messageview.cfm?catid=328&threadid=96153&highlight_key=y&keyword1=reduction).

Why?
