STM-Multifrontal QR: Streaming Task Mapping Multifrontal QR Factorization Empowered by GCN

Multifrontal QR algorithm, which consists of symbolic analysis and numerical factorization, is a high-performance algorithm for orthogonal factorizing sparse matrix. In this work, a graph convolutional network (GCN) for adaptively selecting the optimal reordering algorithm is proposed in symbolic an...
