Description (last modified by seanl) (diff)

scan_intervals, in a for-loop, has a __syncthreads() and calls another device function scan_block that has a bunch of __syncthreads(). As threads do not exit the loop all at once, scan operations hang indefinitely at __syncthreads() on devices with Comput Capability 1.0.
