Two cores can contend without using the same variable. Work from byte addresses and the course's 64-byte permission unit, count completed transfers, and separate a layout improvement from a changed algorithm.
Lesson | After it you can... |
|---|---|
Classify sharing by logical data and physical line. | |
Compare identical writer schedules with preserved full-line values. | |
Choose separation while accounting for footprint and locality. | |
Build a controlled address-level diagnosis. |
Read the four lessons in order. The earlier write-transfer lesson supplies the message mechanism; this topic adds addresses, repeated work and a falsifiable layout experiment.
No. Different words in one line still use one exclusive permission. The relevant boundary is the physical coherence line, not a source-language field.
