Abstract: We consider computing the QR factorization with column pivoting (QRCP) for a tall and skinny matrix, which has important applications including low-rank approximation and rank determination.

SubtreeLU is a high-performance parallel sparse LU factorization algorithm for SPICE-like circuit simulation. It is designed to be used in circuit simulation software, particularly for solving large ...

Abstract: Sparse LU factorization is a vital technique in solving circuit linear equations, However, irregular data access patterns contribute to unsatisfactory computational efficiency and excessive ...
