hello,
i have a master process with an initial group. Now he spawns another
process using MPI_Comm_Spawn() & then merges it into the current group
using MPI_Intercomm_merge().
The operations performed are successful, except for the spawned process
initializing MPI i.e (child doesnt run MPI_Init()). I came along this on
the mpi-forum website:
"An implementation may automatically establish communication before
> >MPI_INIT is called by the children. Thus, completion of MPI_COMM_SPAWN
> >in the parent does not necessarily mean that MPI_INIT has been called
> >in the children (although the returned intercommunicator can be used
> >immediately). ( End of advice to users.) "
> >
> >ny ideas how can this be solved ?
thanx
Junaid
