Performance Analyzer Skill

Purpose

Analyzes performance benchmarks and profiling data from CUDA, CPU, memory, and system tests. Automatically parses benchmark output, identifies performance bottlenecks, tracks metrics over time, and generates actionable optimization insights.

Capabilities

Benchmark Parsing

• CUDA kernel benchmarks (GFLOPS, TFLOPS, execution time)
• CPU benchmarks (GFLOPS, multi-core performance)
• Memory bandwidth tests
• Custom benchmark formats (CSV, JSON, text output)

Analysis Features

• Performance regression detection
• Bottleneck identification
• Comparison across runs/configurations
• Statistical analysis (mean, std dev, percentiles)
• Speedup calculations
• Efficiency metrics

Tracking

• Historical performance data
• Trend analysis over time
• Configuration impact analysis

Usage

The skill automatically loads when you:

• Ask to analyze benchmark results
• Request performance comparisons
• Need to identify bottlenecks
• Want to track performance over time
