To address the issue of stockpile information sharing for the whole stockpiles in the bulk port，we present a research program based on the distributed shared memory (DSM) technology，on the basis of the intelligent stacking and reclaiming control system.The data sharing function of multiple server systems for material machines is realized in the central control room，and the operator can obtain quickly and accurately the stack-type data of the material pile.As a result，the rescan time is saved for the material machine，and the stacking and reclaiming efficiency is improved.
