ECgate

is a Unix server (soon to be changed to a Linux server) where each user has directories:

- HOME: Small permanent files, daily backup/snapshot. Quota: 3.6 GB. To check quota: ecquota
- SCRATCH: Temporary data, removed regularly. Quota: 100 GB
- SCRATCHDIR: Files are autodeleted after end of job. Part of SCRATCH and quota.


HPCF

(High performance computing facility) is the supercomputer (c2a) where each user has directories:

- HOME: Small permanent files, daily backup/snapshot. Quota: 320 MB. To check quota: quota
- SCRATCH: Temporary data, removed regularly. Quota: 25 TB.
- SCRATCHDIR: Autodeled after end of job. 
- PERM: Large paermanent files, no backup. Quota: 26 GB. Accessible from ECgate as /c2a/perm

The two systems use the same name convension - but different file systems.


On both ECgate and HPCF you can access 2 different archives.

1) MARS which contains the meteorological data.


2) ECFS (ECMWF File storage system):

This is a User Archive where you can store long-term data on tape. On ECFS you have two domains:

- ec: Permanent domain where files are stored indefinitively.
- ectmp: temporary domain where files are stored for 90 days after which they are automatically deleted (and cannot be recovered).

To store/access fiels in ECFS you must issue explicit commands which is set-up to use a UNIX like interface. Commands are same as for unix but starting with "e": els, ecd, ecat.. For a manual of the commands type "man els".

els lists your data under ec:
ls lists your data under $HOME
