ttperf 0.1.9

A Python CLI wrapper for profiling Tenstorrent's TT-Metal tests

ttperf - TT-Metal Performance Profiler

A streamlined CLI tool for profiling Tenstorrent's TT-Metal tests and extracting device kernel performance metrics

✨ Features

• Automated Profiling: Seamlessly runs Tenstorrent's TT-Metal profiler with pytest
• CSV Analysis: Automatically extracts and parses performance CSV files
• Real-time Output: Shows profiling progress in real-time
• Performance Metrics: Calculates total DEVICE KERNEL DURATION
• Simple CLI: Easy-to-use command-line interface
• Flexible: Supports named profiles and various test paths
• Operation-based Profiling: Profile specific operations by name (e.g., ttperf add)
• Dynamic Configuration: Customize tensor shape, dtype, and layout for operations
• Config File Support: Set defaults via ~/.ttperf.yaml or ./.ttperf.yaml
• CI-friendly: --quiet flag suppresses decorative output; --verbose enables debug logging

🚀 Quick Start

Installation

# Install from PyPI (recommended)
pip install ttperf

# With YAML config file support
pip install "ttperf[yaml]"

Or install from source:

git clone https://github.com/Aswincloud/ttperf.git
cd ttperf
pip install -e .

Configuration

ttperf automatically searches for your TT-Metal installation using a simple two-step process:

# Option 1: Set PYTHONPATH to your tt-metal location
export PYTHONPATH=/path/to/your/tt-metal
ttperf add

# Option 2: Run from within tt-metal directory (or any subdirectory)
cd /path/to/your/tt-metal
ttperf relu

tt-metal Path Search Order:

1. PYTHONPATH environment variable (if specified)
2. Current working directory (walks up directory tree to find tt-metal root)

Basic Usage

# Run profiling on a specific test
ttperf test_performance.py

# Run with a custom profile name
ttperf my_profile pytest test_performance.py

# Run on a specific test method
ttperf tests/test_ops.py::test_matmul

# Profile specific operations by name
ttperf add
ttperf relu
ttperf matmul

# Custom tensor configuration
ttperf add --shape 1,1,32,32 --dtype bfloat16 --layout tile
ttperf relu --shape 1,1,64,64 --dtype float32 --layout row_major

# Memory options
ttperf add --dram # Use DRAM memory (default)
ttperf relu --l1 # Use L1 memory

# CI-friendly (no emoji/decorative output)
ttperf --quiet add

# Copy CSV output to a directory
ttperf add --output-dir ./results/

# Enable verbose debug logging
ttperf --verbose add

📋 CLI Reference

ttperf [OPTIONS] [PROFILE_NAME] [pytest] <test_path_or_operation>

Options:
 --version Show version information
 --help, -h Show this help message
 --list-ops, -l List all supported operations
 --debug, -d Show real-time profiler output
 --verbose, -v Enable verbose logging (debug messages)
 --quiet, -q Suppress decorative/emoji output (for CI)
 --shape SHAPE Tensor shape (e.g., 1,1,32,32)
 --dtype DTYPE Data type: bfloat16/bf16, float32/fp32/f32, int32/i32
 --layout LAYOUT Memory layout: tile, row_major/rm
 --memory-config CONFIG Memory configuration: dram, l1
 --dram Use DRAM memory (default)
 --l1 Use L1 memory
 --output-dir DIR Copy generated CSV to this directory

⚙️ Config File

Create ~/.ttperf.yaml (global) or ./.ttperf.yaml (project-local) to set defaults:

# ~/.ttperf.yaml
shape: 1,1,32,32
dtype: bfloat16
layout: tile
memory_config: dram
output_dir: ./results

CLI flags always override config file values.

💡 Usage Examples

Test File Profiling

ttperf test_conv.py

Named Profile

ttperf conv_benchmark pytest test_conv.py

Specific Test Method

ttperf tests/ops/test_matmul.py::test_basic_matmul

Operation-based Profiling

# Basic operations
ttperf add
ttperf subtract
ttperf multiply

# Activation functions
ttperf relu
ttperf sigmoid
ttperf tanh
ttperf gelu

# Mathematical operations
ttperf sqrt
ttperf exp
ttperf log

# Comparison operations
ttperf gt
ttperf lt
ttperf eq

# Reduction operations
ttperf max
ttperf min
ttperf sum

# Backward operations
ttperf add_bw
ttperf relu_bw

Dynamic Configuration

ttperf add --shape 1,1,32,32
ttperf relu --shape 2,3,64,128
ttperf add --dtype float32
ttperf add --layout row_major
ttperf add --shape 1,1,64,64 --dtype float32 --layout row_major
ttperf add --dram --shape 1,1,128,128
ttperf relu --l1 --dtype float32

List All Supported Operations

ttperf --list-ops
# or
ttperf -l

Output Example

Auto-generated profile name: temp_test_add
Running test...

============================================================
TEST SUMMARY
============================================================
Test: add
Status: PASSED
Configuration: shape=(1, 1, 32, 32), dtype=bfloat16, layout=tile, memory_config=dram (custom)
CSV Path: /path/to/profile_results.csv
DEVICE KERNEL DURATION [ns] total: 1234567.89 ns
============================================================

🔍 How It Works

1. Command Parsing: Analyzes input arguments to determine profile name and test path/operation
2. Config Loading: Reads ~/.ttperf.yaml or ./.ttperf.yaml for defaults (CLI flags take priority)
3. Operation Detection: If an operation name is provided, maps it to the corresponding test method
4. Dynamic Configuration: If custom configuration is provided, sets environment variables for the test
5. Profile Execution: Runs the Tenstorrent's TT-Metal profiler with the specified test
6. Output Monitoring: Streams profiling output in real-time (with --debug)
7. CSV Extraction: Parses the output to find the generated CSV file path, verifies it exists
8. Performance Analysis: Reads the CSV and calculates total device kernel duration
9. Output Copy: Optionally copies the CSV to --output-dir if specified

📊 Performance Metrics

The tool extracts the following key metrics:

• DEVICE KERNEL DURATION [ns]: Total time spent in device kernels
• CSV Path: Location of the detailed profiling results
• Real-time Progress: Live output during profiling (with --debug)

🔧 Configuration Options

Shape Configuration

• Format: Comma-separated integers (e.g., 1,1,32,32)
• Default: (1, 1, 1024, 1024)
• Example: --shape 2,3,64,128

Data Type Configuration

• Valid Options: bfloat16 (or bf16), float32 (or fp32/f32), int32 (or i32)
• Default: bfloat16
• Example: --dtype float32

Layout Configuration

• Valid Options: tile, row_major (or rm)
• Default: tile
• Example: --layout row_major

📦 Requirements

• Python 3.8+
• pandas
• Tenstorrent's TT-Metal development environment
• pytest
• PyYAML (optional, for config file support)
