Different workloads on HPC

The training focuses on different ways to allocate resources on supercomputers and parallelisation schemes used to speed up calculations

Modern supercomputers are massive parallel machines with up to hundreds of cores on node and even thousands of nodes connected via fast network interface. To utilise fully those machines, one needs to know about parallelisation techniques and queuing system options of resource allocation. This training will show different ways that SLURM allocates resources and how to apply them to different computations and workloads.

Agenda

• Serial jobs
• Embarrassingly parallel jobs
• Intranode calculations
  • Types of parallelisation 
  • Granularity of resource allocation 
• Multinode calculations 
• Gpu calculations
• Array jobs - high throughput jobs
• Job dependencies
• Brief review of available applications that use described methods of parallelisation 

Duration

3 hours

Target audience

Training is intended for users who have started running their own calculations and need to learn about different methods of allocating resources on HPC clusters. 

Requirements

We recommend doing this training after completing Running Calculations the HPC way training provided at ACK Cyfronet AGH.

Technical prerequisites:

• PLGrid account at https://portal.plgrid.pl/,
• an active affiliation at https://portal.plgrid.pl/users/affiliations,
• access to Ares supercomputer at https://portal.plgrid.pl/services/103,
• membership in the plggtraining team - the activation link will be sent after registration.

The above prerequisites are required to actively participate in the hands-on exercises.
In case of no active affiliation or PLGrid account, please contact the organisers at training@cyfronet.pl. 

Participants' computers should be equipped with software that allows SSH connections. On Windows, it is recommended to use Windows Terminal after checking if OpenSSH is installed. We advise against using Putty.

Venue

The workshop will be conducted online on the Zoom platform. The meeting link will be sent to registered participants.

Language

English/Polish - dependent on the participants.
