You play as a member of a RAPIDS development team tasked with finding and fixing a mysterious deadlock that's preventing their GPU-enabled distributed software from running. To solve the problem, you'll need to traverse a complex stack of multiple programming languages, libraries, and interconnects, and use tools like GDB to identify and resolve the issue. As you eliminate possible causes and narrow down the culprit, you'll eventually learn the true cause of the deadlock and how to fix it.
