These 20-30 minute talks cover all topics from core infrastructure talks, to project's using LLVM's infrastructure. Attendees will take away technical information that could be pertinent to their project or general interest.

Tutorials

Tutorials are 50-60 minute sessions that dive down deep into a technical topic. Expect in depth examples and explanations.

Lightning Talks

These are fast 5 minute talks that give you a taste of a project or topic. Attendees will hear a wide range of topics and probably leave wanting to learn more.

Quick Talks

Quick 10 minute talks that dive a bit deeper into a topic, but not as deep as a Technical Talk.

Student Technical Talks

Graduate or Undergraduate students present their work using LLVM.

Panels

Panel sessions are guided discussions about a specific topic. The panel consists of ~3 developers who discuss a topic through prepared questions from a moderator. The audience is also given the opportunity to ask questions of the panel.

Sponsor Meet & Greet

Attendees can meet with sponsors regarding an explore job opportunities, discuss their work, or just chat about the uses and applications of LLVM.

Reception

After a full day of technical talks and discussions, join your fellow attendees for an evening reception to continue the conversation and meet even more attendees with food and drinks provided.
