Resources per team

• HPC Cluster Navigator. Full description at   https://www.uc.pt/lca/computing-resources/navigator-cluster/

Resource Access

• Direct ssh to Navigator cluster after creating the respective account.

Resource management

• Slurm is used as resource management.  New users have access to full documentation about the system and software environment in a internal Wiki page,

Software management

• Users can install software, and have access to  system wide applications and tools installed via environment modules. 

Documentation

• Full documentation about the system and software environment in a internal Wiki page is available to new users. Some information is provided in UC-LCA site.

Support

• Support is available via ticketing system (helpdesk). Tickets response are limited to business days. Moderate knowledge of Linux and Job Schedulers is expected.

Resource location

• Portugal

Overview

Per user resource

• Suitable flavors for UC-LCA-UC HPC depend on the Slurm partition used (For a fixed CPU time duration agreed with SDC3 hosts):

  • up to 1024 cores with 4GB/core;

  • up to 160 cores with 8GB/core

  • SMP system with 72 cores and 3TB memory.

  • disk up to 10TB

Software installed

• Linux CentOS. Users can install software, and have access to  system wide applications and tools installed via environment modules. 

Volume of resource

• A share disk space quota is assigned to each team.

GPUs if any

• GPU partition provides access to Nvidia  V100  GPUs  with 16GB memory.

Open the accounts

• Open accounts by request (email to helpdesk.lca@uc.pt). 

Logging in

• Use a ssh client to login to navigator https://www.uc.pt/lca/computing-resources/navigator-cluster/#general-information

Authentication  

• Authentication is done by private/public key exchange. Users are encouraged to protect their private key with a passphrase. See  https://www.uc.pt/lca/cluster-access/#request-access

How to run a workflow

•  Information in the internal Wiki page

Software management

• Users can install software and have access to  system wide applications and tools installed via environment modules. 

Containerization

• Users can use Singularity to run containers on the Navigator cluster.

Documentation

• Full documentation about the system and software environment in a internal Wiki page is available to new users. Some information is provided in UC-LCA site.

• For Navigator Cluster, resource management is done via SLURM job scheduler. Each team will be assigned to an account with a predefined number of hours and disk quota.

• Statistics of resource usage will appear on the login page and the sbank utility is available as well. 

• Support is available via a ticketing system (helpdesk.lca@uc.pt). Tickets response are limited to business days. Moderate knowledge of Linux and Job Schedulers is expected.

• Teams making use of UC-LCA resources in their publication, they should Acknowledge it as follows :

  • The authors acknowledge the Laboratory for Advanced Computing at University of Coimbra for providing {HPC, computing, consulting} resources that have contributed to the research results reported within this paper or work. See  https://www.uc.pt/lca/about/
