GPU Runtime Idle Timeout Configuration and VM Recycling
Google Colab provides GPU runtimes with a maximum continuous usage limit of 12 hours. However, the platform also implements an idle timeout mechanism that can trigger VM recycling when no cell execution is detected for a period of time. While documentation suggests a guideline of approximately 90 minutes for idle disconnections, the actual behavior appears i
