Hello to all Lammps users!
I've got a programming question. Let's say that I modify the file:
compute_heat_flux.cpp

Hello to all Lammps users!
I've got a programming question. Let's say that I modify the file:
compute_heat_flux.cpp
introducing these lines:
-----------------------------------------
if (universe->me == 0) {
std ::ofstream myfile;
myfile.open ("file.dat",std::ios_base::app);myfile << "Component: " << vector[3]<< "\n";
myfile.close();
}
---------------------------------just after the MPI_All_Reduce in ComputeHeatFlux::compute_vector().
In my mind the output file should be indipendent of the number of processors I
use but I do not observe this. I get the same number for one and two
processors, but from three the numbers are different. Is there something wrong?
*how* different are those numbers?
