问题 The　grid　computing　is　a　new(66)technology　connecting　the　distributed　and(67)resources　to　the　high-speed　network　and　integrating　a　super-computer　of　processing　capacity.　The　significance　and　architecture　of　the　grid　computing　is　explained.　Several　kernel　technology　such　as　OGSI,　resource　management,　task　management,　task　scheduling,　high　rate　communication　and　security　are　described.　Aiming　at　the　particularity　of　the　grid　computing　environment　a　mechanism　similar　to　the　technology　of　the　search　engine　is　designed　to　registry,　discovery　and(68)the　resources　in　the　grid.　The　whole　model　of　the　resource　management　is　built　by　connecting　task　manager　in　the　local　resource　management　system　to　others　with　P2P　model.　The　task　may　migrate　among　the　task　managers　in　order　to(69)the　load.　The　task　users　summit　may　be　executed　in　relatively　tight　resource　set,　which　will　not　only　decrease　the　total　communication　overheads　of　the　whole　task　but　also(70)the　performance　of　the　system.
