Currently, I have multiple GPU nodes and pool them through slurm. Enroot.conf adopts the default configuration. At this time, the image pulled by enroot can only be cached on the same node. When running a task on another node, you need to Re-pulling the image results in a waste of time.

enroot.conf :

#ENROOT_LIBRARY_PATH /usr/lib/enroot

#ENROOT_SYSCONF_PATH /etc/enroot

#ENROOT_RUNTIME_PATH ${XDG_RUNTIME_DIR}/enroot

#ENROOT_CONFIG_PATH ${XDG_CONFIG_HOME}/enroot

#ENROOT_CACHE_PATH ${XDG_CACHE_HOME}/enroot

#ENROOT_DATA_PATH ${XDG_DATA_HOME}/enroot

#ENROOT_TEMP_PATH ${TMPDIR:-/tmp}

I hope that when slurm submits a task, it can share the image cache regardless of the node, so as to reduce the time of pulling the image.
