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.

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.

Registration Fees and Deadlines

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.

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 iccs.conference@intellegibilis.com. 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.
The applicable cancellation fee will be 50% of the registration fee plus any bank handling charges.
Cancellations requested after the above deadline will not be accepted.
