Then, just as in the case of an MPI_Recv, we can use MPI_Get_count to find out how many occurrences of a given datatype were read. If it is less than the number of items requested, then end-of-file has been reached. 3. 7— C++ Version The MPI Forum faced a number of choices when it came time to provide C++ bindings for the MPI-1 and MPI-2 functions. The simplest choice would be to make them identical to the C bindings. This would be a disappointment to C++ programmers, however. MPI is object-oriented in design, and it seemed a shame not to express this design in C++ syntax, which could be done without changing the basic structure of MPI.

In other words, MPI_Get is a nonblocking operation. To ensure that the operation is complete, we need to call MPI_Win_fence again. The next few lines in the code compute a partial sum mypi in each process, including process 0. We obtain an approximation of π by having each process update the value pi in the window object by adding its value of mypi to it. First we call another MPI_Win_fence, this time on the piwin window object, to start another RMA access epoch. Then we perform an accumulate operation operation using MPI_Accumulate(&mypi, 1, MPI_DOUBLE, 0, 0, 1, MPI_DOUBLE, MPI_SUM, piwin); The first three arguments specify the local value being used to do the update, in the usual (address, count, datatype) form.

For accessing data using the individual file pointer or explicit offsets, each process can specify a different view if it needs to. 6). The function for setting the file view is MPI_File_set_view; the view can be changed any number of times during the program. MPI datatypes, both basic and derived, are used to specify file views.
