Shared memory and dev/shm directory
Posted: Fri Nov 24, 2023 11:38 am
I would like to use vasp compiled by option -Duse_shmem to reduce memory comsumption of machine
learning training calculations. Vaspwiki reports problems encountered in some occasions, when
shared memory has been used. I was told from our supercomputer centre that I can use vasp compiled
by -Duse_shmem, if vasp uses /dev/shm directory, because that is cleaned after batch job is ended.
I would like to ask, whether vasp compiled using vasp.6.4.1.tgz uses /dev/shm directory and if not, what
should be done that it would do so. Thank you!
