Samples for CUDA Developers which demonstrates features in CUDA Toolkit

Quick Overview

CodeXL is an open-source, comprehensive tool suite for GPU debugging, profiling, and optimization. Developed by AMD, it supports both OpenCL and OpenGL applications, providing developers with powerful features to analyze and improve their GPU-accelerated software performance.

Pros

Comprehensive toolset for GPU debugging, profiling, and optimization
Supports both OpenCL and OpenGL applications
Provides detailed performance analysis and visualization
Free and open-source

Cons

Development has been discontinued (last update in 2018)
Limited support for newer GPU architectures and APIs
Steep learning curve for beginners
Some users report stability issues on certain systems

Getting Started

To get started with CodeXL:

Download the latest release from the GitHub repository.
Install the software following the instructions in the README file.
Launch CodeXL and create a new project or open an existing one.
Use the various tools (debugger, profiler, analyzer) to examine your GPU application's performance.

Example workflow:

1. Clone the repository:
   git clone https://github.com/GPUOpen-Archive/CodeXL.git

2. Build the project (on Windows):
   cd CodeXL
   Scripts\AMDTPrepareWindows.bat
   Scripts\BuildCodeXLFullWindows_VS14.bat

3. Launch CodeXL:
   Build\CodeXL\VS14\x86\Release\bin\CodeXL.exe

4. Create a new project and start analyzing your GPU application

Note: As CodeXL is no longer actively maintained, consider using more up-to-date alternatives for newer projects or GPU architectures.

Competitor Comparisons

Pros of cuda-samples

Extensive collection of CUDA-specific examples and tutorials
Regularly updated with new CUDA features and optimizations
Directly supported by NVIDIA, ensuring compatibility with latest GPUs

Cons of cuda-samples

Limited to CUDA and NVIDIA GPUs, not cross-platform
Focuses on individual features rather than providing a comprehensive development environment
Lacks integrated profiling and debugging tools

Code Comparison

CodeXL (OpenCL example):

cl_int err;
cl_kernel kernel = clCreateKernel(program, "vector_add", &err);
clSetKernelArg(kernel, 0, sizeof(cl_mem), &buffer_A);
clSetKernelArg(kernel, 1, sizeof(cl_mem), &buffer_B);
clSetKernelArg(kernel, 2, sizeof(cl_mem), &buffer_C);

cuda-samples (CUDA example):

__global__ void vectorAdd(const float *A, const float *B, float *C, int numElements)
{
    int i = blockDim.x * blockIdx.x + threadIdx.x;
    if (i < numElements)
    {
        C[i] = A[i] + B[i];
    }
}

Summary

CodeXL offers a comprehensive development environment for multiple GPU platforms, including profiling and debugging tools. cuda-samples, on the other hand, provides a rich set of CUDA-specific examples and tutorials, focusing on NVIDIA GPUs and the latest CUDA features. The choice between them depends on the developer's specific needs and target hardware.

CodeXL Retirement

CodeXL is no longer being actively developed or supported by AMD and is being archived. For the latest tools from AMD please visit one of the following links:

for ROCm Development https://github.com/RadeonOpenCompute/ROCm
for Gaming/Graphics Development https://gpuopen.com

Some of our partners will continue to develop and support CodeXL on their platforms and are maintaining their own forks of this codebase.

CodeXL

CodeXL is a comprehensive tool suite that enables developers to harness the benefits of GPUs and APUs. It includes powerful GPU debugging, comprehensive GPU profiling, and static OpenCLâ¢, OpenGLÂ®, VulkanÂ® and DirectXÂ® kernel/shader analysis capabilities, enhancing accessibility for software developers to enter the era of heterogeneous computing. CodeXL is available as a standalone user interface application for WindowsÂ® and LinuxÂ®.

Motivation

CodeXL, previously a tool developed as closed-source by Advanced Micro Devices, Inc., is now released as Open Source. AMD believes that adopting the open-source model and sharing the CodeXL source base with the world can help developers make better use of CodeXL and make CodeXL a better tool.

To encourage 3rd party contribution and adoption, CodeXL is no longer branded as an AMD product. AMD will still continue development of this tool and upload new versions and features to GPUOpen.

Installation and Build

Windows: To install CodeXL, use the provided executable file CodeXL_*.exe
Linux: To install CodeXL, use the provided RPM file, Debian file, or simply extract the compressed archive onto your hard drive.

Refer to BUILD.md for information on building CodeXL from source.
