Uniform Utilization of hardware resources ensures scalability:
Uniform Hardware Utilization Through Time (All program Phases use the hardware uniformly)
Uniform Utilization of Hardware Threads (All Hardware Threads are Busy)
Uniform Use of Software Threads (There are enough threads)
Uniform Cache Set Use in the Cache Hierarchy (No cache sets are over subscribed)
Uniform Physical Memory Use (All memory boards [...]
