The FAQ has been updated to describe all storage spaces available on PlaFRIM and the quota command to display their usage and limits.

PlaFRIM is back
The shutdown is now over and PlaFRIM is available again.
Closure of PlaFRIM from April 24 to 27, 2020
In order to proceed with the annual total electric shutdown of the building scheduled for 25 April, we have to shut down the PlaFRIM infrastructure from 24 April during the afternoon.
A normal situation is scheduled on Monday 27 April during the morning.
Thank you for your understanding.
New parallel storage space
A new parallel BeeGFS file system (see https://www.beegfs.io/content/) is now available on PlaFRIM. You will find a /beegfs/<LOGIN> directory on all PlaFRIM nodes.
This parallel file system replaces the /lustre storage which is no longer under warranty and is not recommended.
The data in this directory are not saved. The quota is 1 TB per user.
If you need to write/read massively and/or in parallel, this is the preferred file system unlike your /home/<LOGIN> directory.
Information on all available storage spaces can be found in the plafrim website’s FAQ (see here).
Please do not hesitate to contact us if you need further information
New AMD nodes available
New AMD compute nodes are now available (see Hardware Documentation/) :
– diablo [01-04]: 2 * AMD EPYC 7452 32-Core Processor and 256 GB RAM
– diablo05 : 2 * AMD EPYC 7702 64-Core Processor and 1 TB RAM
To reserve them, use the “amd” or “diablo” constraints.
Please do not hesitate to contact us if you need further information.
End of Network instability on bora[001-040] and devel[01-02]
The network switch was replaced on January 15. Since then, we have not observed any outages.
We confirm that the problems of access to the bora [001-040] and devel [01-02] nodes are solved.
Please do not hesitate to contact us if you need further information.
New PlaFRIM nodes fingerprint
Many of you are reporting connection problems related to changing the fingerprint of development servers when connecting to SSH.
To make sure you can accept this change, you will find below the new fingerprint of these servers :

PlaFRIM shutdown from 1st to 6th august 2018
The server room of the Talence building will be undergoing refurbishment work on the cooling system and will require a total shutdown of PlaFRIM from 1st August starting at 12.00 with a restart during the 6th of August.
Thank you for your understanding.
Cleaning of /lustre storage and quota implementation
The Luster filesystem “/lustre” is close to be saturated (in terms of inodes). If the system reaches the saturation, creation of new files on /lustre will no longer be possible.
It is therefore necessary for each user to clean up his personal directory /lustre/<LOGIN>.
We remind you that the storage space /lustre is a temporary work area and is not saved.
To store your non-temporary and big data, it is also possible to use the iRODS service. Information on it is available here
We will implement a quota in terms of number of file per user (~ 400 000).
Thank you for your understanding,
