MEMFS RAM storage
In order to allocate RAM for the storage of temporary files, please add the "-C memfs” parameter to your job specification. For example, use the following directive in your batch script: #SBATCH -C memfs
A storage volume will be set up for your job, referenced by the $MEMFS environmental variable. Please note that memory allocated to MEMFS storage counts towards the total memory allocated for your job and declared through "--mem" or "--mem-per-cpu".
Caution: When using MEMFS for file storage, be aware of the following limitations:
- this method is only available for single-node jobs
- the total amount of memory consumed by your job, including any MEMFS storage, must not exceed the value declared through "--mem".
- this method may only be used if the total memory requirements of your job (including MEMFS storage) do not exceed the memory available on a single node (1024 GB per standard Athena node).
- when using MEMFS, it is recommended to request the allocation of a full node for your job.
