hi all,
After some calculation with mpi, I call the gnuplot(with an interface)
to plot the result. However, if I run the program over a multinode
network, it always complain that I haven't set the DISPLAY variable.
However, if I run the program in a local machine, nothing goes wrong.
It implies that the setting in a single local machine is all right.
Here is my code
...
if (rank==0)
{
// plot the resutl
}
...
Notice that I only do the plotting in rank 0.
