MARTE12_ — Cannot precisely allocate an application to an execution platform described as a series of composite structures.

Title: Cannot precisely allocate an application to an execution platform described as a series of composite structures. Description : Consider an execution platform : a rack composed of 3 boards, each boards has a general-purpose processor and an accelerator. The rack and the board are structured classes defined with composite structure diagrams. The pseudo-code below provides an informal description of the platform: Rack

Board

GPP

How to precisely address the accelerator on the second board of the rack and allocate application elements on it ? The current allocation mechanism allows one to allocate an application on gpp property of the Board class but does not express that the second board is specifically designated.

Closed No Change

In order to achieve this purpose, let’s create istancespecification of the Rack and the boards. Let’s call them respectively rack1, board1, board2 and board3 and define rack1.board[0] = board1, rack1.board[1] = board2 and rack1.board[2] = board3. You can also define more precisely the Board instance specifications creating instance specifications of the gpp and accelerator. Then you can address the precisely each created instance specification in the allocation description.
