Software management with GNU Guix

by Ludovic Courtes
Documentation, Latest News | No Comments

In addition to module, PlaFRIM users can manage software environments using GNU Guix, a general-purpose package manager. Why use Guix? Guix can be used in addition to and in parallel with module. There are several reasons why it might be useful to you: Guix provides more than 7,500 software packages including: utilities such as tmux, compiler toolchains (GCC, Clang), Python software (Scikit-Learn, NumPy, etc.), HPC libraries (Open MPI, MUMPS, PETSc, etc.). Pre-built binaries are usually available for packages you install, which makes installation fast. You get to choose when you upgrade or remove packages you've installed for yourself, and can roll…

Cleaning of /lustre storage and quota implementation

by Julien Lelaurain
Latest News | No Comments

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: https://www.plafrim.fr/en/irods-storage-resource/ We will implement a quota in terms of number of file per user (~ 400 000).…

Preemption queue “testpreempt”

by Nathalie Furmento
Documentation | No Comments

The queue "testpreempt" The queue "testpreempt" allows to run jobs outside the usual limits on unused computing resources (during the day but mostly at night and on weekends) without blocking the access to the resources for jobs running on the other queues. This means the jobs can be stopped ("preempted") suddenly at every moment if a regular job needs the ressources. The job will be restarted when the resources become available. The code must regularly backup its state ("checkpoint") and make sure the backup is safe (the job could be stopped while backing up) and be able to restart on…

iRODS Storage Resource

by Nathalie Furmento
Documentation | No Comments

Introduction An iRODS Storage Resource is available at the MCIA (mésocentre Aquitain). It allows to backup your research data. Information IMPORTANT : Encryption is not available (without authentification). Data are unencrypted both on the disks and on the network. If necessary, you need to encrypt data by yourself. Data are scattered over 7 sites (Bordeaux and Pau). IRODS keeps 3 copies of every file: one nearby the storage resource the data was first copied on, one at the MCIA (near Avakas), one in another storage resource. Default quota : 500Gb. Help : https://redmine.mcia.univ.bordeaux.fr/projects/irods How to use the system One needs…
