High performance scientific solvers for manycore architectures

 

A register-oriented tridiagonal algorithm for Intel MIC architecture, which can outperform the implementation with Intel MKL library and the GPU version with Nvidia cuSPARSE library; a novel sparse triangular solver together with newly-introduced sparse-level-tile matrix layout for heterogeneous manycore CPU SW26010 that powers Sunway TaihuLight, which can outperform the latest method on KNC processor in 1856 matrices and the latest method on K80 GPU in 1672 matrices in all the 2057 square matrices of the Florida Matrix Collection.

I/O Monitoring and Tuning for Leading Supercomputers

An end-to-end and light weight I/O resource monitoring and diagnosis system for the 40960-node Sunway TaihuLight supercomputer, simultaneously collects and correlates I/O tracing/profiling data from all the compute nodes, forwarding nodes, storage nodes and metadata servers, to reveal correlations between system performance bottlenecks, utilization symptoms, and application behaviors; An automatic mechanism for application-adaptive dynamic forwarding resource allocation scheme, which improves applications’ I/O performance by up to 18.9x, eliminates most of the inter-application I/O interference, and has saved over 200 million of core-hours during its test deployment on TaihuLight for 11 months.

Parameter estimation for earth system models

Building a cost-efficient parameter analysis and parameter estimation framework for earth system models, successfully introducing dynamic parameter screening method, fast optimization algorithm and the cost-saving scheme with short-term hindcasts based on Cloud-Associated Parameterizations Testbed of Lawrence Livermore National Laboratory, and successfully applied to different earth system models: GAMIL2 (9% improvement for a synthesized performance metrics), CAM5 (10% improvement) and CLM-CASA model (12% improvement).

Interactive ensemble framework for ocean-atmospheric coupling analysis

Building an extensible framework to quantitatively analyze the effect of atmospheric noise with interactive ensemble method; over 79.9% of the simulated monthly variability of NAO is caused by atmospheric noise; the irregular ENSO cycle partly arises from atmospheric noise; more reasonable simulation for the relationship between ENSO and SST in the central North Pacific subtropical gyre region by using interactive ensemble coupled model.
