Nord4

NEW essential changes!​

Nord4 is part of the old MareNostrum4, inheriting all the software previously available on MN4. Users can access the same software environment and utilize the existing toolset without any modifications.

To explore the available software modules, users can execute the following command:

module avail

This command provides a comprehensive list of all accessible software modules within the Nord4 cluster.

IMPORTANT

Users who need to access software from StarLife or Nord3 can do so; however, it is important to note that software from different environments cannot be used simultaneously. Users must choose to work with either Nord4, Nord3, or StarLife software at any given time.

To facilitate migration for users from StarLife and Nord3 to Nord4, we have introduced compatibility features that seamlessly port your workflows, ensuring a smooth and efficient transition.

StarLife Software Availability​

We have created a dedicated module that grants access to all StarLife software. To ensure consistency, the software is now available under new paths located at /gpfs/apps/SL/, making it easy for users to transition without disrupting their workflows.

module load starlife

This command loads all the available software that was present on the StarLife cluster into Nord4.

Singularity​

Due to differences in operating systems and libraries, some applications may not function as expected when loading the starlife module. To resolve this, we provide a Singularity image with an OS similar to StarLife.

To use it, simply run the following commands (example: loading and running R):

module load starlife-singu 
module load R
starlife_singu R --help
  • The first command loads the wrapper that configures Singularity with the StarLife cluster image, including all its available software. The second command loads the R module that has been sourced from the StarLife software environment rather than Nord4.
  • The last command starlife_singu will use the wrapper to execute a program (in this case R).

Nord3 Software Availability​

We have created a dedicated module that provides seamless access to Nord3 software, ensuring continuity for users migrating to Nord4. To maintain consistency and simplify the transition, all Nord3 software is now accessible under new paths at /gpfs/apps/NORD3/. This structured approach helps users adapt easily while preserving their existing workflows without disruption.

module load nord3

This command loads all the available software that was present on the Nord3 cluster into Nord4.

Singularity​

Due to differences in operating systems and libraries, some applications may not function as expected when loading the nord3 module. To resolve this, we provide a Nord3 image with an OS similar to Nord3.

To use it, simply run the following commands (example: loading and running R):

module load nord3-singu 
module load R
nord3_singu R --help
  • The first command loads the wrapper that configures Singularity with the Nord3 cluster image, including all its available software. The second command loads the R module that has been sourced from the Nord3 software environment rather than Nord4.
  • The last command nord3_singu will use the wrapper to execute a program (in this case R).
