Co-located Events

We are proud to announce three co-located events with ICCS: the ExCALIBUR Task Parallelism Workshop; the SEAVEA Workshop: VVUQ on the Exascale; and the SEAVEA Hackathon.

Registration to ICCS gives access to the first two, which take place during the conference. The SEAVEA Hackathon is scheduled for June 24th and is ticketed separately.

For any questions about registration and payments, you can reach us at
For any other questions, please use the dedicated secretariat contact available within each of the sections below.

Please read below for further details.

ExCALIBUR Task Parallelism Workshop

When: 21 June 2022
Length: 3 hours
Contact: Marion Weinzierl

About:: Future supercomputing architectures are expected to exhibit unprecedented hardware parallelism. This parallelism has to be “harvested” on the software side. Traditional, global, loop-based parallelism and notably the bulk-synchronous/BSP paradigm are insufficient, and developers might have to go back to the drawing board and uncover alternatives to equip their code with higher concurrency. Task-based parallelism is one tool to write such new, highly concurrent software. It phrases programs as sequence of steps including their causal dependencies, but leaves the decision what (aka which task), when and where to execute a task to a task runtime.

The crosscutting ExCALIBUR project on Exposing Parallelism – Task Parallelism aims to develop a data-driven taskification toolset and workflow, to investigate task features that are missing within mainstream tasking approaches, and to establish taskification training and an experience exchange landscape.

This workshop aims to bring researchers, research software engineers and vendors together to discuss the current state of the art, issues, experiences and ideas for tasking in research software.

SEAVEA Workshop: VVUQ on the Exascale

When: 23 June 2022
Length: 3 hours
Contact: Diana Suleimenova

About:: The availability of supercomputers permits studies on topics of major societal importance, including climate change, medicine and energy production, conducted at ever increasing scales and scope. However, fundamental principles of scientific investigation must be widely enforced to ensure the reliability of and confidence in the results generated. This hinges on our ability to (i) validate (V) them, normally against experimental observations, but sometimes compared to “gold standard” numerical results; (ii) verify (V) them, to ensure that the correct mathematics is used, and (iii) equip the output data with meaningful bounds on errors which come from rigorous uncertainty quantification (UQ).

Within this workshop, which will be a fully hybrid event, we will initiate a discussion about VVUQ specifically in the context of the emerging exascale computing infrastructures. We invite speakers from diverse backgrounds to present their perspectives on how we can enforce simulations with rigorous VVUQ at these scales, what techniques show particular promise in making VVUQ scalable and tractable, and what challenges we face to make exascale simulations as robust as they are detailed.

We also invite everyone, speakers and participants alike, to take part in discussions around these central themes, and to contribute towards specific strategies to improve the quality and uptake of VVUQ in a HPC simulation context. These strategies will then form a backbone for the activities in the SEAVEA project (and beyond) over the coming year.

SEAVEA Hackathon

When: 24 June 2022
Length: 9AM – 5PM
Contact: Diana Suleimenova

About:: For those interested in making their simulations more robust and their results more credible, we are organising a Hackathon on Verification, Validation and Uncertainty Quantification (VVUQ) for HPC simulations on the 24th of June 2022. The Hackathon will focus on the SEAVEA toolkit (SEAVEAtk), which facilitates VVUQ for applications irrespective of their source domain.

The Hackathon will allow you to interact with our SEAVEAtk experts, who will help you apply your choice of SEAVEAtk tools on your own codes and applications. And if you already are a SEAVEAtk user, then we will have support on hand to help you add more rigorous VVUQ to your application. The toolkit provides a variety range of tools to:

  • create VVUQ procedures (EasyVVUQ),
  • to facilitate the creation of surrogate models for multiscale simulations (EasySurrogate)
  • to automate the complex workflows emerging from these procedures (FabSim3),
  • to enable the efficient execution of large numbers of jobs on computational resources (QCG Pilot Job Manager),
  • to provide convenient means to use HPC facilities for users (QCG-Now) and user-developers (FabSim3 and QCG-Client),
  • and to make creating coupled multiscale simulations easy, and to then enable efficient Uncertainty Quantification of such models using advanced semi intrusive algorithms (MUSCLE3)
  • MOGP

The Hackathon will take place in-person on the 24th of June 2022 at Brunel University London, the day after the ICCS conference from 9AM until 5PM. However, there will be an opportunity to participate remotely for those who wish to do so.

How to Register

Registration Fees and Deadlines

Single Rate (Regular & Student)
Until 31 May 2022
ExCALIBUR Task Parallelism Workshop 60 EUR
SEAVEA Workshop: VVUQ on the Exascale 60 EUR
SEAVEA Hackathon 60 EUR
All 3 Workshops 145 EUR

Please note that, while ICCS 2022 and these co-located workshops are taking place in the United Kingdom, the conference’s financial and accounting headquarters is in the Eurozone (Euro Area), hence the pricing in EUR.

The registration fee includes:

  • Full access to the workshop(s)
  • Registration materials, workshop guide/program, and giveaway items (for in-person participants)
  • Lunch and coffee breaks for the workshop day
  • All taxes and VAT (where applicable)

Payment Methods and Details

You can pay by bank transfer or credit card (through Stripe).

If you pay by bank transfer, please note that:

  • All bank payments must be made in EUR and all bank transfer costs must be covered by the sender. Failure to do so may result in the cancellation of your registration.
  • We will need you to send us a bank transfer confirmation document/receipt. This will allow us to trace your payment and will serve as temporary proof until payment is effectively received on our end.

If you pay by credit card through Stripe, please note that we do neither store nor have access to your credit card details. Your credit card is processed through Stripe, which is one of the most well-known and reputed payment platforms in the world.

The payment receipt will be emailed to you after your registration is complete, or given to you when you check in at conference welcome desk. Please allow for some time in this, as our accountancy will be processing hundreds of invoices for the main conference.

Note to on-site registrants: we will NOT charge credit cards directly on site. On-site registration payments must be made in cash or through Stripe.

By clicking the button below you will be taken to the ICCS secretariat website.
You will be required to enter your participant data.
Detailed payment instructions will also be given.

Cancellation Policy

1. The Organizing Committee reserves the right to cancel a registration.

2. Your registration is considered complete only after payment on our end has been received and all required participant data has been provided.

3. Cancellations must be made in writing to Cancellation fees will be calculated based on the date when the secretariat receives this notice.

4. Workshops participants can cancel their registration until 7 June 2022, 23:59 CET.
