XUI quickly/ efficiently notifies CPU of events to handle, without relying on polling and waste CPU cores, reducing interrupt overhead

"All the modern high-performance processors right now flush the in-flight instructions when they receive an interrupt, but this work shows that we don’t actually need to flush those instructions, leading to efficiency of dealing with interrupts... more efficient than polling, which has an entire CPU core constantly check for events, like incoming tasks flows... awarded the 2025 Best Paper Award at the 2025 ASPLOS Conference"
