Lock Granularity: Coarse vs Fine-Grained

This generated surface maps a learner-facing curriculum unit to its canonical source routes.

Curriculum surface​

  • Open learner-facing unit
  • Curriculum path: content/curriculum/systems/semester-05-os-networking/module-03-concurrency-synchronization/concepts/cluster-02-locks-and-mutual-exclusion/06-lock-granularity-coarse-vs-fine-grained-primary.md
  • App: systems
  • Semester: semester-05-os-networking
  • Module: module-03-concurrency-synchronization
  • Unit kind: concept
  • Curation level: module_curated

Learning objectives​

  • Explain Lock Granularity: Coarse vs Fine-Grained in terms of interleavings, invariants, and failure modes rather than prose alone.
  • Use Lock Granularity: Coarse vs Fine-Grained to predict what can go wrong in shared-state code before reaching for an implementation fix.
  • Use ostep to connect the learner page to real synchronization APIs, scheduling effects, and recovery strategies.

Prerequisites​

  • Comfort with threads, process state, and interleaving from earlier operating-systems concepts.
