This paper organizes the landscape around seven coupled themes---number formats, floating-point emulation, emerging architectures, hardware/software co-design, relation to other approximations, software design, and precision as a multilevel resource ---and synthesizes the state of the art, future directions, and open q...

A lightweight selector captures the sparsity pattern of the Cholesky factor and routes the matrix to one of three regimes: dense, sparse, or an intermediate semisparse regime, which achieves the lowest total factorization time in every regime.

Cheetah is presented, a set of kernel-level optimizations that systematically redesign the execution pipeline of just-in-time compiled matrix-free finite element operators without modifying the mathematical formulation or user-facing programming model and demonstrates that low-level kernel restructuring is essential fo...
