Re: [OMPI users] 1.8.6 w/ CUDA 7.0 & GDR Huge Memory Leak

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

Ramps up over time, we had a bunch of locked up nodes over the weekend and have traced it back to this. Let me see if I can share more details, I will review with everyone tomorrow and get back to you, Rolf vandeVaart wrote: Hi Steven, Thanks for the report. Very

Hi Steven, Thanks for the report. Very little has changed between 1.8.5 and 1.8.6 within the CUDA-aware specific code so I am perplexed. Also interesting that you do not see the issue with 1.8.5 and CUDA 7.0. You mentioned that it is hard to share the code on this but maybe you could share

[OMPI users] 1.8.6 w/ CUDA 7.0 & GDR Huge Memory Leak

Hi All, Looks like we have found a large memory leak, Very difficult to share code on this but here are some details, 1.8.5 w/ Cuda 7.0 — no memory leak 1.8.5 w/ cuda 6.5 — no memory leak 1.8.6 w/ cuda 7.0 — large memory leak 1.8.5 w/ cuda 6.5 — no memory leak mvapich2 2.1 GDR — no issue on
