Dear Users,</p>
<p>This is to inform you that $CINECA_SCRATCH area on Marconi100 cluster is<br />
currently more than 90% full. This may lead to problems to the filesystem<br />
causing failures of users' jobs and preventing access to that filesystem. We<br />
strongly remind all users that the SCRATCH area is conceived for just<br />
temporary storage of users' files and therefore we recommend to keep its<br />
occupancy as low as possible so as to avoid issues with users' jobs and<br />
activities.</p>
<p>To prevent the critical threshold to be reached, we decided to activate two<br />
procedures:</p>
<p>- on 14th of January 2021 we will enable an automatic procedure that sets a<br />
temporary quota of 20 TB on user's occupancy of the SCRATCH area when the<br />
global occupancy exceeds 88%. We will inform you when the quota is applied.<br />
As a consequence of the quota, jobs expected to write in SCRATCH area when<br />
you are occupying more that 20 TB will fail. The quota will be kept until the<br />
occupancy of the area goes below the critical threshold.</p>
<p>- on 26th of January 2021 we will activate a periodic cleaning procedure.<br />
Files are daily cancelled by an automatic procedure if not accessed for more<br />
than 40 days.</p>
<p>We remind Users that for long term storage of files you can use $WORK and/or<br />
$DRES resources where there are no cancellation policies and that survives<br />
for the entire life of the project.<br />
For more info on both areas and procedures, please consult our dedicated HPC<br />
