Memory hierarchy skill for caches, coherence, and locality. An agent skill from mohitmishra786/low-level-dev-skills.
- Works in 7 steps: Hierarchy (typical desktop/ server) → Cache line and associativity → False sharing → …
- Explaining cache levels
- SKILL.md covers Purpose, When to Use, Workflow and Common Problems, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Memory Hierarchy And Caches is an agent skill from mohitmishra786/low-level-dev-skills. Memory hierarchy skill for caches, coherence, and locality. Use when explaining cache levels, associativity, false sharing, prefetching, or MESI coherence. Activates on queries about cache hierarchy, L1 L2 L3, false sharing, cache line, prefetch, or cache coherence.
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
When your agent uses it
- Explaining cache levels
Example prompts
- “/memory-hierarchy-and-caches”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit bdc5847. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are c and bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Memory Hierarchy And Caches loads about 771 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 212 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- memory-hierarchy-and-caches
- description
- Memory hierarchy skill for caches, coherence, and locality. Use when explaining cache levels, associativity, false sharing, prefetching, or MESI coherence. Activates on queries about cache hierarchy, L1 L2 L3, false sharing, cache line, prefetch, or cache coherence.
Memory Hierarchy and Caches
Purpose
Teach CPU memory hierarchy: cache levels, associativity, line size, coherence protocols, false sharing, and prefetch behavior — architectural depth complementing optimization practice in skills/low-level-programming/cpu-cache-opt.
When to Use
- Explaining why padding fixes scalability
- Choosing struct layout for multicore
- Interpreting cache miss counters
- Understanding DMA vs CPU cache on embedded SoCs
Workflow
1. Hierarchy (typical desktop/ server)
Registers
├── L1d / L1i (per core, ~32 KiB, ~4 cycles)
├── L2 (per core, ~256 KiB – 1 MiB)
├── L3 (shared last-level, MiB – tens of MiB)
├── DRAM (hundreds of cycles)
└── Storage / NUMA remote (much slower)Embedded MCUs may have only tightly-coupled memory (no L2/L3).
2. Cache line and associativity
- Line size: commonly 64 bytes on x86/ARM64 (verify with
getconf LEVEL1_DCACHE_LINESIZE) - Set-associative: line maps to one set, competes within ways
- Conflict misses: many aliases same set
3. False sharing
/* Bad — two atomics on same cache line */
struct {
atomic_int counter_a;
atomic_int counter_b;
} stats;
/* Good — pad to cache line */
struct alignas(64) {
atomic_int counter_a;
char pad[64 - sizeof(atomic_int)];
atomic_int counter_b;
} stats;4. Coherence (multicore)
MESI states: Modified, Exclusive, Shared, Invalid. Writes invalidate other cores' copies of the line — why atomics and locks ping cache lines.
5. Prefetching
#ifdef __builtin_prefetch
for (int i = 0; i < n; i++) {
__builtin_prefetch(&data[i + 8], 0, 3);
process(data[i]);
}
#endifHardware stride prefetchers detect sequential access; random access misses.
6. Measurement

/memory-hierarchy-and-caches Diagnose false sharing in this per-thread stats arrayCommon Problems
| Symptom | Cause | Fix |
|---|---|---|
| Scaling collapses | False sharing | Line-align per-thread data |
| High LLC misses | Working set > cache | Block algorithms; NUMA pin |
| DMA incoherence | CPU cache vs device | Flush/invalidate on MCU; dma_sync on Linux |
| Prefetch hurt | irregular access | Remove manual prefetch |
| Huge struct copies | AoS cold lines | SoA layout — see cpu-cache-opt |
