ParaGraph: Accelerating Graph Indexing through GPU-CPU Parallel Processing for Efficient Cross-modal ANNS

This repository includes the codes for the SIGMOD's Workshop DaMoN 2025 paper ParaGraph.

The master branch contains the codebase for the ParaGraph paper.

Getting Started & Reproducing Experiments

This section guides you through setting up the project and reproducing the experiments presented in our paper.

File Format

All ~bin data files adhere to the following structure (consistent with the Big-ANN competition format):

1. Number of vectors: uint32 (4 bytes)
2. Dimension of vectors: uint32 (4 bytes)
3. Vector data: Sequentially listed vector components.

Data Acquisition and Preparation

• You can obtain the required datasets from the RoarGraph repository.
• We utilize Python scripts for the necessary data transformations.
• For the index construction process, we exclusively use the base vector set (base) and the corresponding ground truth data (gt).

The base vector data (base_data) is structured as an num x dim matrix, where:

• num: Signifies the total number of vectors.
• dim: Denotes the dimensionality of each vector.

Note: These two parameters, num and dim, must be pre-defined within the source code.

To ensure efficient GPU memory management, the handling of the ground truth (gt) data is modified. Specifically, the number of ground truth neighbors recorded for each query vector (often denoted as gt_num or top_k) is limited or adjusted to 128.
