Diagnose a Memory-Hierarchy Bottleneck in a Trading-System Hot Path

Diagnose a Memory-Hierarchy Bottleneck in a Trading-System Hot Path. Advanced challenge in analysis. Analyzing real datasets and building models that drive d...
The Brief
What you'll do, and what you'll demonstrate.
Profile a 14us hot path with perf, identify the dominant memory-hierarchy bottleneck, and propose a measured layout change toward a sub-6us target.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
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
- Use perf and Linux perf-counters to diagnose memory-hierarchy issues
- Distinguish L1, L2, and L3 miss patterns and their typical fixes
- Apply cache-aware data-layout techniques (SoA, hot/cold splitting)
- Communicate micro-architectural findings to a non-specialist tech lead
