CPU MF (Measurement Facility)
The CPU MF (Measurement Facility) was used in order to analyze L1 cache misses and the cache levels where they were resolved.
The following CPU MF parameters were used:
- CPUMF L1MP
- L1 miss percentage. This is the percent of instructions that incur an L1 miss.
- CPUMF L2P
- Percent of L1 misses sourced from cache level 2.
- CPUMF L3P
- Percent of L1 misses sourced from cache level 3.
- CPUMF L4LP
- Percent of L1 misses sourced from cache level 4 from the local book .
- CPUMF L4RP
- Percent of L1 misses sourced from cache level 4 of a remote book.
- CPUMF MEMP
- Percent of L1 misses sourced from memory.
