All of this is a lot of information, so here is a simple example using MPI_Isend, MPI_Irecv, MPI_Wait and MPI_Test, showing you how to use all of these calls. We consider two or three processes. The data is stored in a variable called buffer , defined as an array of int of size buffer_count .

MPI Example 6: MPI_Wtime() and MPI_Barrier() 4. MPI Example 7: MPI_Reduce() 5. Both implementations fully support Open MPI or MPICH2. Example program. Here is a "Hello World" program in MPI written in C. In this example, we send a "hello" message to each processor, manipulate it trivially, return the results to the main process, and print the messages. In the example above with 4 processes and a list of 8 integers, we need 3 levels (0, 1, 2). Timing: The parallel time as well as the individual time of each process is determined.

Parallel C code (cont’d) comm = MPI_COMM_WORLD; I am aware of these examples, but I do not know any Fortran, thus I can not understand much. So finding at least an example with MKL and ScaLAPACK in C would be critical for me.
