Heterogeneous Task Scheduler

C++17 DAG scheduling for mixed CPU and GPU workloads

⚡

DAG-first execution

Build dependency-aware pipelines with TaskGraph, TaskBuilder, and scheduling policies that span CPU and GPU work.

🔄

Validate and iterate without CUDA hardware by using the project's CPU-only build and test path.

🎯

Combine scheduling policies, retry behavior, barriers, resource limits, and event hooks in one runtime surface.

💾

Use the CUDA execution path, stream manager, and memory pool for accelerator-backed stages when available.

📊

Export execution statistics and trace-oriented profiling data to understand scheduler behavior.

🛡️

Start from runnable examples, public headers, and GitHub Pages guides instead of a README mirror.

Compose dependency-aware workloads with a single C++ API.
Keep the default contributor path CPU-only while still supporting CUDA-backed execution.
Use examples and public headers to evaluate the library without reverse-engineering the repository.

Layer	Responsibilities
Builder API	`TaskGraph`, `TaskBuilder`, task groups, barriers, and futures
Scheduler	Dependency resolution, policy selection, retries, profiling, and events
Execution	CPU worker threads, CUDA execution path, stream management, and resource limits
Device services	Memory pool, CUDA helpers, CPU-only stubs, and runtime utilities

bash

git clone https://github.com/LessUp/heterogeneous-task-scheduler.git
cd heterogeneous-task-scheduler
scripts/build.sh --cpu-only
scripts/test.sh

For editor/LSP integration, the repository provides a cpu-only-debug CMake preset and workspace settings in .vscode/.
