Abstract
Disclosed are methods and systems for dynamically determining data-transfer paths. The data-transfer paths are dynamically determined in response to an instruction that facilitates data transfer among execution lanes in an integrated-circuit processing device operable to execute operations in parallel. In addition, embodiments include an integrated-circuit processing device operable to execute operations in parallel, including the capability of providing confirmation information to potential source lanes, the confirmation information indicating whether the potential source lanes may send data to requested destination lanes during a data-transfer interval.
