New CÉCI accounts are no more created on NIC4, and existing accounts are no more automatically renewed.
Existing users are strongly encouraged to backup their important data (/home and /scratch), delete unneeded ones, and migrate to NIC5.
Hosted at ULiège (SEGI facility), NIC4 features 128 compute nodes, each with
two 8-core Intel E5-2650 @ 2.0 GHz processors and 64 GB RAM (4 GB/core).
Nodes are interconnected via QDR Infiniband and have exclusive access to a
144 TB FHGFS parallel filesystem.
Suitable for:
Massively parallel jobs (MPI, several dozens of cores) with heavy communication
and/or high parallel disk I/O.
Max wall time: 3 days.
Resources
- Home directory (20 GB quota per user)
- Working directory
/scratch($GLOBALSCRATCH) - Internet access available on compute nodes
- Default batch queue*:
3 days max, 448 cores/user, 64 jobs/user, max 32 running, 256 CPUs/job
