TL;DR: Preliminary efforts on developing and optimizing applications on the TaihuLight system are reported, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation.

TL;DR: An ultra-scalable fully-implicit solver is developed for stiff time-dependent problems arising from the hyperbolic conservation laws in nonhydrostatic atmospheric dynamics and a highly efficient hybrid domain-decomposed multigrid preconditioner is proposed that can greatly accelerate the convergence rate at the extreme scale.

TL;DR: This paper presents a detailed methodology of implementing and optimizing the double-precision general format matrix-matrix multiplication (DGEMM) kernel on the emerging SW26010 processor, which is used to build the Sunway TaihuLight supercomputer.

TL;DR: This work presents a computation-communication overlapping technique to reduce the inter-process communication overhead, a locality- aware blocking method to fully exploit on-chip parallelism with enhanced data locality, and a collaborative data accessing scheme for sharing data among different threads.

TL;DR: This article utilizes a block multicoloring approach for parallelization and proposes methods such as requirement-based data mapping and customized gather collective to enhance the effective memory bandwidth in HPCG.
