Dear LAMMPS developers and users,
solid-state non-equilibrium thermal conductivity simulations have been very consistent in
memory usage: they use 2.3 G and are very well balanced across different nodes.
Recently, I have had my jobs fail due to “std::bad_alloc”. After
tracking the memory usage, I found that two nodes use more memory and the
amount increases sharply in time. Would anyone know why this may be?I had something similar happen before and found out that it was because of invoking compute centro/atom too regularly. I am not sure what has caused a similar problem to occur again.
The images below are screen shots of the virtual memory on different nodes after 1.3 hrs, 1.4 hrs, and 1.8 hrs. I've also attached the output file.
I appreciate any input I may receive.
