Johannes Doerfert, LLVM and OpenMP luminary, dies at 36
Remembering Johannes Doerfert
Johannes Doerfert, a prolific LLVM contributor and OpenMP target offloading code owner, passed away on September 17, 2026, at 36 after a battle with cancer. He designed the Attributor framework, advanced GPU offloading across NVIDIA, AMD, and Intel hardware, and mentored Google Summer of Code students for years. A fixture at LLVM Developers' Meetings, he spoke at 11 meetings over 11 years. Donations to the LLVM Foundation in his memory will be matched up to $50K.
LLVM Developer, OpenMP contributor, Beer drinker, not in this order.

I had the pleasure of working with Johannes as part of Google Summer of Code in 2020 and 2021 working on LLVM. He mentored me and many students over the years.
I remember in 2020 he would meet with us at 7AM his time to accommodate every student he was working in different parts of the world (Turkey, Greece, China, Japan iirc), I was the one from Turkey.
I had Coffee with him and his wife few months back. He was so full of life despite everything.
He touched the lives of many people. What a great life lived despite being so short.

Johannes was a leader in his field. LLVM is on a different path with his passing. We are lucky to have worked with him.

Wasn't familiar with Johannes but what a body of work. RIP. You can tell he was one of the real ones.
