SHA256:isyTpjgQgAQ15a3IAVziZLTOgYeTcJfW8NJGq44LcyM (ED25519)

Hardware Configuration:

  • virgo2024 : 2 x Intel(R) Xeon(R) Platinum 8480+ @ 2.00GHz; 112 cores per node; 2 threads per core; 2 TB RAM

Filesystems:

/u

shared home filesystem; GPFS-based; user quotas (currently 100 GB, 1M files) enforced; quota can be checked with ‘/usr/lpp/mmfs/bin/mmlsquota’.

/virgotng

shared scratch filesystem (8.0 PB); GPFS-based; no quotas enforced. NO BACKUPS!

Compilers and Libraries:

The “module” subsystem is implemented on ORION. Please use ‘module available’ to see all available modules.

  • Intel compilers (-> ‘module load intel’): icx, icpx, ifort

  • GNU compilers (-> ‘module load gcc’): gcc, g++, gfortran

  • Intel MKL (‘module load mkl’): $MKL_HOME defined; libraries found in $MKL_HOME/lib/intel64

  • Intel MPI 2024.0 (‘module load impi’): mpicc, mpigcc, mpiicc, mpiifort, mpiexec, …´

Similar to the HPC systems, this module tree is hierarchical.
To find a module and information about the available versions or what dependencies need to be loaded first one can use the ‘find-module’ command.

Batch system:

  • no workload manager is available on VIRGO

  • limits in terms of CPU shares are set
