Sorry, now really attached. Hi, I have attached a proposal for ``Flexible RMA Synchronization for MPI-3''. Aim of the proposal is to give a single process or a set of processes of application programs the possibility to signal a target process (i.e. a \MPI/ process from which data was read or to which data was written by RMA communication calls) that the writing of data or reading of data is completed and that the target process is able to proceed.
