After a long hiatus of the compiler social, Lorenzo is joining us to talk about the exciting work happening at NVIDIA that you have probably heard about, namely cuTile/TileIR. As usual there will be pizza, snacks, beer, and soft drinks after the event for participants, sponsored by NVIDIA. **Astract:** GPU programming has evolved significantly over the past decade, driven by rapid hardware innovation such as Tensor Cores and new numerical formats. However, the gap between high-level productivity frameworks and low-level performance-centric programming models continues to widen. In this talk, we introduce cuTile and TileIR, a new block-level programming model and intermediate representation designed to simplify high-performance GPU development while preserving forward compatibility with evolving NVIDIA architectures. cuTile provides a tile-centric abstraction for data-parallel workloads, accessible from Python, while TileIR—an MLIR-based low-level IR integrated with CUDA—offers a stable, portable foundation for targeting tensor cores and future hardware generations. Together, they establish a middle ground between usability and control, enabling expressive kernel development without sacrificing performance. We present the programming model, illustrate it with examples, discuss performance considerations, and, if time permits, take a deeper dive into the core abstractions behind TileIR: https://github.com/NVIDIA/cuda-tile **Location:** The event is taking place in the room G59 in the CAB building of ETH Zurich at the Zentrum campus. Enter from Universitätstrasse 6.

"Behind the Curtain" is a new women’s group built around real conversations and genuine connection. It’s a place where you can show up as yourself, talk about the things that actually matter, and feel truly heard — without pressure and without judgment. We intentionally leave work, small talk and our phones at the door, making space instead for honest stories, thoughtful questions and meaningful connection. To keep the space intimate and make sure everyone has room, spots for each gathering are limited. While each event stands on its own, the hope is that familiar faces will return over time, allowing trust to grow and real friendships to form. Whether you come with something on your heart or simply to hold space for others, you’re welcome here exactly as you are.

Join us for our next GraphQL Meetup on **March 12th** in Zürich! The event will start at **6:00 PM**, with time for networking and the first talk beginning at **6:30 PM**. Location, drinks, and food are generously provided by **Digitec Galaxus**. If you’d like to host one of our future events, please reach out to us at contact@chillicream.com. The event will be **hybrid**. We strongly encourage you to join us in person for the full experience, but we will also provide a livestream for remote attendees. When you sign up, please let us know whether you’ll attend in person or online. **Schedule** **18:00 – 18:30** Welcome & Networking **18:30 – 19:00** **GraphQL Batching: DataLoaders and Batch Resolvers Explained** \- Michael Staib GraphQL servers rely on batching to avoid the N+1 problem, but where should batching actually happen? In this talk, we explore three common approaches: DataLoaders, Batch Resolvers, and breadth-first (BFS) execution. While all aim to reduce redundant data fetching, they solve different problems and live at different layers of your stack. We will examine how each approach works, when to use one over the other, and how modern GraphQL servers implement batching under the hood. Along the way, we will look at practical execution details like field merging and batching across multiple operations. By the end, you will have a clear mental model for GraphQL batching and the trade-offs between DataLoaders, Batch Resolvers, and BFS execution. **19:00 – 19:30** **Semantic Introspection** \- Pascal Senn GraphQL's rich type system makes it an ideal foundation for agents to explore and work with APIs. The SDL provides the structure agents need to reason about capabilities and data. Queries let them retrieve information, while mutations enable them to take action. In practice, however, production GraphQL schemas are often too large to fit in the context window and difficult to understand without additional context. So what if agents could interact with any GraphQL API in a generic, reliable way? In this session, we'll look at the challenges of agentic interactions with GraphQL and how semantic introspection could unlock a new way for agents to navigate the schema and interact with GraphQL APIs more reliably. **19:30 – 20:00** **The Future of GraphQL Federation: Composite Schemas in action** \- Tobias Tengler GraphQL federation enables teams to compose multiple services into a single unified API. But the federation ecosystem is evolving. In this talk, we introduce the GraphQL Composite Schema specification, a new open standard developed under the GraphQL Foundation and co-created by Apollo, The Guild, and ChilliCream. Rather than introducing yet another competing approach, the Composite Schemas specification aims to standardize and modernize GraphQL federation by addressing limitations of earlier federation protocols. We will explore how GraphQL APIs can be federated using Composite Schemas and how queries are planned and executed across services. Along the way, we will demonstrate the first implementation of the specification with Hot Chocolate Fusion 16 and share some of the design decisions behind it. By the end, you will understand what Composite Schemas are, how they improve GraphQL federation, and how to start using them with Fusion.

Central Bank Digital Currency (CBDC) With Digital Currency they can: Have a complete government dossier on every detail of your life. Use your purchase history to maintain a detailed social credit score for every person. Provide tax breaks to corporations who hire people with admirable social credit scores. Only grant government contracts to corporations with employees with admirable social credit scores. Adjust health insurance premiums to incentivize people to develop admirable social credit scores. Connect your social credit score with a digital ID to encourage you to look at only approved web sites when surfing the internet. Viewing conspiracy web sites could lower your Social Credit Score and make it difficult to get a job. With their electronic chain around your neck, they can control where, when, how you travel, what food you are allowed to buy etc. They will love the power to only allow you to use your digital money only where they want you to shop and allow you to buy only what they prefer you to buy. Require you to have to have a license to use your money. They will call it a Digital Currency License. Require you to take any vaccine they want you to take to maintain your digital currency license. Tax you in ways we have not even imagined. Adjust your income tax rate based on your social credit score. Use AI to increase your income tax rate if you eat too many hamburgers because they will tell you eating too many hamburgers will increase global warming. This is just one example of many behaviors they might not approve of. Adjust individual prices for different individuals. They will be able to make you pay more per pound for hamburger if you purchased too much red meat during the past 30 days. Require you to buy so many pounds of soy burger for every pound of hamburger to save the planet and increase the profits for the soy burger manufacturers. Turn off the digital money of people they consider to be spreading misinformation. Turn off the digital money of people they consider to be dangerous conspiracy theorists. Turn off your money at 8 PM if they want a curfew at 8 PM Turn off your money in another state if they do not want you to drive to another state without permission. Turn off your money when buying guns or ammo if they do not want you to buy guns or ammo. Turn off your digital money more than three miles away from your home if they want you to stay within three miles of your home during the next epidemic. Etc. etc. etc. From the standpoint of the government, one beauty of digital money is that your money is one “state emergency” away from being the government’s money. All they have to do is to take your digital money out of your Central Bank Digital Account for the “good of all”. It is not as easy for them to do this with physical cash, gold, stocks, or silver etc. Anything they **can** do, they will do. The essence of slavery is control. Digital Currency will enable them to make you, their slave. (in a global digital concentration camp). .
