Tune a Multicore Pipeline with NUMA-Aware Sharding. Advanced challenge in code. Writing production code that solves real engineering problems, earn a blockch...
The Brief
What you'll do, and what you'll demonstrate.
Redesign a multicore query-execution worker to scale efficiently to 32 cores on a 2-socket box using NUMA-aware sharding and prove the collapse goes away.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply NUMA-aware sharding and per-socket worker pools
- Use perf c2c to measure cross-socket coherence traffic
- Configure NUMA-aware allocators correctly
- Benchmark scaling efficiency, not just speedup
