Hi all, Hopefully this mail gets posted in the right thread...
I have noticed the (I guess same) leak using OpenMPI 1.8.6 with LAMMPS, a molecular dynamics program, without any use of CUDA. I am not that familiar with how the internal memory management of LAMMPS works, but it does not appear CUDA-related. The symptoms are the same: OpenMPI 1.8.5: everything is fine OpenMPI 1.8.6: same setup, pretty large leak Unfortunately, I have no idea how to isolate the bug, but to reproduce it: 1. clone LAMMPS (git clone git://git.lammps.org/lammps-ro.git lammps) 2. cd src/, compile with openMPI 1.8.6 3. run the example listed in lammps/examples/melt I would like to help find this bug but I am not sure what would help. LAMMPS itself is pretty big so I can imagine you might not want to go through all of the code...
