Julia API

This page explains how to install the Julia version of HPR-QP.

1. Prerequisites

  • Julia ≥ 1.10.4

  • CUDA: NVIDIA GPU with proper CUDA driver

  • System tools: Standard C/C++ toolchain (for dependencies)

Check that CUDA is available in Julia:

using CUDA
CUDA.versioninfo()

2. Pick the Right Solver and Clone the Repository

If you need to solve a LASSO problem (with an \(l_1\) regularizer) or a QAP instance where the matrix form of \(Q\) is unavailable, please refer to the HPR-QP_QAP_LASSO module.

git clone https://github.com/PolyU-IOR/HPRQLP.git
cd HPR-QP_QAP_LASSO

otherwise, for convex QP (COP) problems where the matrix form of \(Q\) is available, please refer to the HPR-QP module.

git clone https://github.com/PolyU-IOR/HPRQLP.git
cd HPR-QP

Or download and extract the ZIP file from GitHub.

3. Install Dependencies

Inside the project root, run:

julia --project -e 'using Pkg; Pkg.instantiate()'

This will install all required Julia dependencies (including CUDA.jl).
