Abstract
A mechanism synchronizes among processors of a processing engine in an intermediate network station. The processing engine is configured as a systolic array having a plurality of processors arrayed as rows and columns. The mechanism comprises a barrier synchronization mechanism that enables synchronization among processors of a column (i.e., different rows) of the systolic array. That is, the barrier synchronization function allows all participating processors within a column to reach a common point within their instruction code sequences before any of the processors proceed.
