OK, I found that if I inovke the master process
with mpirun as in
mpirun ./orange -master
Then the remote process is successful in the MPI_Init call.
I would like to avoid using mpirun if possible. It seems to
be responsible for setting up communication between the
two machines in so
I am trying to add a host at run time and spawn a slave process.
The slave process starts but hangs or crashes in MPI_Init().
Code for the slave process is
#include
int main(int argc,char * argv[])
{
ofstream ofs("junk11");
ofs << "calling MPI_Init" << endl;
int err=MPI_Init(&argc,&argv);

As a result rhe slave processes are wasting time waiting for the
message. If I use MPI_Send
