ملخص المقالة :
گريدهاي محاسباتي بهرهبرداري از منابع توزيعشده محاسباتي را براي کاربردهايي که به محاسبات پرحجم نیاز دارند، فراهم مینمایند. توسعه برنامههايي که قادر به استفاده از اين امکانات باشند، يکي از چالشهاي پيش روي محاسبات گريدي ميباشد. در اين مقاله، با ارائه یک مدل برنامهنويسي موازي مبتني بر عاملهاي سيار بر روي گريد، تلاشي میباشد که به منظور حل اين مشکل صورت پذيرفته است. ارائه اين مدل، که با توسعه بستر گريدي به نام Alchemi و افزودن خواص و نيز فرامين راهبري عاملها به آن محقق گشته است، به کاربر اجازه ميدهد تا با استفاده از حرکت عاملها و ارتباط ميان آنها، برنامه موازي خود را توسعه دهد. اين ايده از نوآوريهاي اين مقاله محسوب ميشود. به منظور ارزيابي این سيستم، الگوريتم ضرب ماتريسها و نیز يافتن Convex Hull مجموعهاي از نقاط در سيستم مزبور پيادهسازي شدهاند.
