Grid　portal　is　the　bridge　between　Grid　and　user.　In　this　paper　a　Grid　portal　system　is　set　up　based　on　GPIR　of　GridPort.　The　Grid　portal　system　provides　an　efficient　means　to　user　for　utilizing　grid　resources,　and　provides　advantaged　condition　for　achieving　effective　information　of　database.　The　user　can　customize　the　application　by　portlet　framework.　In　this　paper　we　also　review　multiple　choices　for　portal　technology　and　explain　why　we　choose　GPIR.　©　2006　IEEE.
