Greetings all,
I use OpenMPI 1.3.3 and I tried to spawn child processes (using MPI_Comm_spawn) and send user-defined-datatypes across processes.The child processes should be ranked from 1-5 while the rank 0 is the manager processes (manager.cpp) . But I get rank 0 for manager process and the child processes also ranked starting from 0 (0-4) . So I cannot send data from manager process to first child processes (which suppose to be rank 1)
Please give any suggestion to resolve this. thanks in advance, umanga
Every group is numbered starting from 0. Using the intercommunicator the ranks 0-4 refer to the other group. All this is the same as using the C inetrface Matthias
