SpComm3D: A Framework for Enabling Sparse Communication in 3D Sparse Kernels

Overview

SpComm3D is an MPI-based framework for building distributed-memeory 3D sparse kernels for CPUs and GPUs. The main feature of SpComm3D is that it efficiently uses sparsity-aware communication in 3D sparse kernels instead of sparsity-agnostic communication.

Currently, SpComm3D contains sparsity-aware implementations for 3D algorithms of two important ML sparse kernels that occur frequently in Graph/Hypergraph Neural Networks:

• Sampled Dense-Dense Matrix Multiplication (SDDMM)
• Sparse Matrix-Dense Matrix Multiplication (SpMM)

To build conv2bin tool:

make conv2bin

To make benchSddmm:

make benchSddmm
