Core Systems Design

The orchestrator combines high-frequency Linux telemetry scans with kernel priority management, governed by 3 distinct storage engine tiers.

Telemetry Collection

Platform-specific Linux parser queries `/proc/[pid]/stat` and `/proc/[pid]/status` directly to fetch real-time stats including Resident Set Size (RSS), peak memory, swap space usage, CPU percentages, and page faults.

Dynamic Classification

Compute process score variables (0-100) based on weighted parameters. Top 10% processes are routed to L1 (HOT), middle 40% to L2 (WARM), and the remaining 50% are relocated to L3 disk (COLD).

Scheduler Controls

Modifies the Linux scheduler behavior by invoking standard `setpriority()` system bindings to boost HOT processes (-10) and de-prioritize COLD processes (10). Suspends and resumes workflows using `SIGSTOP` and `SIGCONT` signals.

Data Routing Engine

L1 uses an unordered map mapped to a custom Pairing Heap to enforce capacity restrictions, L2 relies on a red-black tree (sorted by score), and L3 stores cold indexes in sequential memory vectors.

Manual Data Structures Architecture

Our C++ pipeline maps collected telemetry into 7 concurrent, manually implemented data structures to deliver low-latency analytics.

Max Binary Heap

Maintains process priority rankings. Insertion and peak evictions take O(log N) time, ensuring the highest hotness scores are instantly accessible for promotion queries.

Red-Black Tree Index

Self-balancing Red-Black binary search tree sorted by process hotness scores. Keeps elements balanced to guarantee strict O(log N) lookup, insertion, deletion, and range-based querying.

Multi-Level Skip List

A probabilistic balanced data structure built with multiple linked layers. Upper layers act as express lanes to search and sort nodes in O(log N) average time without tree rebalancing algorithms.

Least Recently Used (LRU) List

Doubly linked list paired with ProcessHashMap index. Relocates processes accessed via `simulateAccess()` to the HEAD of the list in O(1) time. Elements near the TAIL represent eviction candidates when the L1 Cache reaches capacity limits.

Segment Tree Range Sum

Organizes process workload timelines. Divides active system duration slots into binary segment ranges, allowing interval summation and range statistics queries in logarithmic O(log N) time.

Sum: 312m [0-3] Sum: 175m [0-1] Sum: 137m [2-3] P0: 120m [0] P1: 55m [1] P2: 80m [2] P3: 57m [3]

Fenwick Tree (BIT) Focus Sums

Binary Indexed Tree storing cumulative workloads. Provides efficient prefix sum updates in O(log N) time to track system utilization changes dynamically across process groups.

System Execution Sequence

How telemetry flows from standard Linux kernel system files into the storage tiers and scheduling tables.

1

Linux /proc Scan

The C++ LinuxProcessCollector scrapes virtual /proc filesystem metrics (stat and status) every 2 seconds to get RSS memory size, page fault counts, and active CPU usage times.

2

Score & Route

The Analyzer computes hotness scores (0-100) using normalizations, inserting PIDs into the HashMap, MaxHeap, and RB-Tree indexes for priority sorting.

3

Storage Eviction

If L1 Cache exceeds the 10% ceiling, the lowest scoring process is evicted from the Pairing Heap to L2 RAM. Cold items near the LRU TAIL are paged out to L3 Disk.

4

Scheduler Tuning

The orchestrator issues standard `setpriority()` system bindings to boost HOT workloads (-10) and demote COLD background threads (10) to optimize CPU allocation.
