What Occupancy Really Means
Active warps versus the SM maximum.
Meet Occupancy
Each GPU core, called an SM, can keep many warps resident at once. Occupancy measures how full that capacity really is. 🎯
A Simple Ratio
Occupancy is the ratio of active warps on an SM to the maximum warps that SM can hold. More resident warps means a fuller machine.
