I am using a SLURM cluster whithout any root permissions.
I would like to allocate a node but requiring large amount of tmpfs to perform fast computations on large files.
I checked and the target node has enough memory but the default allocated size is rather small (I checked with df -h /mount/foulder).
Of course, as I am not root I cant do mount -o ...
Is there any flag I can pass to salloc to require more tmpfs memory. Something like
salloc --tmpfs 100000
On most clusters, you will have access to /dev/shm in the same way you might have access to /tmp (world writable with sticky bit). If the cluster is configured so, this space will be accounted for in the memory usage of your job so make sure to request enough RAM to hold your file(s).
