DeinoMPI Forum

Hi,

I have written an application(running just on my localhost) that make matrix operations using 1 master and 3 workes. I have done this with MPI 1.0 and so the number of processes was defined statically during the invocation

example: mpirun -np 4 name_application.exe

Now I'd like to know how use MPI_Comm_spawn(...) to split master and slaves codes. Please give me some help about syntax.
regards by salvo

DeinoMPI comes with several examples that use the MPI-2 functions.  The parallel mandebrot generating code was implemented using MPI_Comm_spawn.  You can look at the pmandel_spawn project in the examples solution provided in the examples directory.  The pmandel_spawn.c source file shows a simple master/slave model.
