Good afternoon everyone,
IMPORTANT: Cluster Output Paths
As we indicated last week, from today it will not be possible to write to /groups from the cluster, only /scratch/groups.
This step has been taken to prevent the /groups partition filling up
with data which does not belong in there. If /groups fills up, all users are affected.
To illustrate the point, during last week (when writing
to /groups remained possible) one cluster job generated ~300Gb of data
in /groups which belonged in /scratch/groups. The partition was therefore completely filled up. The consequence was that another user
was unable to run their stimulus code, which depends on there being
space in /groups to log output, and their scanning was delayed
significantly.
More generally, it is important to recognise that storage resources are
limited, and that when the full capacity of partitions is reached many
more people than those who wrote the data may be affected. It would be
appreciated if users who anticipate writing large amounts of data,
could first estimate how much data will be written and then ask us how
best to accommodate the data. In general, we would also like to remind
users of the importance of storing the correct data in the correct
areas; this will avoid us having to take urgent remedial actions in
cases where other users have been affected.
YNiC User Inductions
If
you are aware of any new students/staff that will require access to
YNiC and/or an IT account, they must attend a YNiC user induction. Our final induction date before the Christmas break will be Wednesday 11th December at 2pm. Please ask
them to contact support@ynic.york.ac.uk to sign up.
Hope you have a great week!
Kind regards
Lauren
