The course is organised in collaboration with POP3 CoE, NCC Austria, NCC Czechia, NCC Hungary, NCC Poland, NCC Slovakia and NCC Slovenia.

Virtual Institute—High Productivity Supercomputing (VI-HPS) is an initiative that aims to enhance the productivity of supercomputing applications by providing a comprehensive set of tools and methodologies for performance analysis, debugging, and tuning. It brings together expertise and resources from various organisations to support developing and optimising high-performance computing applications.

The workshop is designed to facilitate collaborative learning and application tuning, with a particular emphasis on teams of two or more participants working with the same or closely related application codes the teams are developing. The first day of the workshop introduces participants to the POP Centre of Excellence (CoE), detailing its services, methodology, and tools for performance assessments and second-level services. On the second day, the focus shifts to getting started with open-source multi-platform tools for analysing MPI+OpenMP application executions on CPU architectures. The third day delves into more advanced usage, including analysing application executions on combined CPU and GPU architectures. During this hands-on workshop, participants will be introduced to the use of Paraver/Extrae and Scalasca/Score-P/CUBE toolsets for CPUs and GPUs. 

Paraver/Extrae is a performance analysis toolset designed for tracing and analysing the execution of parallel applications. Extrae captures detailed execution traces, while Paraver provides powerful visualisation and analysis capabilities to help identify performance bottlenecks and optimise parallel code.

Scalasca/Score-P/CUBE is an integrated performance analysis toolkit for parallel applications. Score-P collects performance data in profiles and execution traces, Scalasca analyses and identifies performance issues, and CUBE facilitates exploration of the results, helping developers tune their applications. 

Additionally, other tools from the POP CoE will be available for participants to utilise throughout the workshop.

Target Audience and Purpose of the Course:

Attendees will learn how to use the parallel performance analysis tools of the Performance Optimisation and Productivity (POP) CoE and a corresponding methodology for applying those tools to assess execution performance and scaling efficiency of their own parallel application codes in a portable fashion.

Level

Intermediate/advanced, as no knowledge of any parallel performance tools is required (though serial code profiling experience is advantageous). However, participants are expected to be familiar with building/running (potentially hybrid, GPU-enabled) parallel applications.

Language

English

Course format

The hands-on parts will only be available for on-site participants, who should bring their codes to work on.

The tutorial/lecture parts will be available to an unlimited number of attendees who can participate online.

Prerequisites

Participants should be familiar with one or more parallel programming paradigms, such as MPI and OpenMP (on CPUs), and preferably also the use of OpenMP, OpenACC, CUDA, or similar (for GPUs). When registering for the workshop, participants should report the programming languages and paradigms employed by their application codes, along with relevant framework/library dependencies. Note that applications using AI/ML frameworks such as TensorFlow are unsuitable for this workshop.

Technical requirements

Participants with their own application code(s) should have these installed and running on Karolina before the event. Also, a representative execution test case should be prepared, suitable for running on a single node in several minutes. The required tools will be available on Karolina (CPU and GPU partitions). However, participants may also install graphical tools on their own notebook computers. Each participant will get access to the mentioned clusters before the event.

The workshop will feature the Paraver/Extrae and Scalasca/Score-P/CUBE toolsets for CPUs and GPUs, with introductions to other tools from the POP CoE that are additionally available.

Practicalities

This training will be a hybrid event. Participants who wish to enjoy the hands-on exercises must attend on-site. The hands-on sessions will not be streamed, and online participants will not get access to the HPC infrastructure.

Technical details about joining will be sent to the accepted registrants before the event. If you are coming to IT4Innovations to attend personally, please bring your own laptop.

Registration

Registration is obligatory. Only registered participants will receive the Zoom link.

Please note that the on-line training is held using Zoom. We advise all participants to download the Zoom application to enjoy full functionality. 

After the number of registrations has reached its maximum or the registration form has been closed, you may want to send us an email stating that you are interested in being put on the waiting list. (Vacancies may occur due to cancellations, etc.) Email to training@it4i.cz

Capacity and Fees

The capacity is limited to 30 participants on-site. Online participation is not limited by capacity.

Please note that the course is open and free of charge for participants from the Member States (MS) of the European Union (EU) and Associated/Other Countries to the Horizon 2020 programme.

The course is free of charge for the eligible participants.
