The Sunway TaihuLight supercomputer: system and applications

Comments on the parallelization efficiency of the Sunway TaihuLight supercomputer

In the world of supercomputers, the large number of processors requires to minimize the inefficiencies of parallelization, which appear as a sequential part of the program from the point of view of Amdahl’s law. The recently suggested new figure of merit is applied to the recently presented supercomputer, and the timeline of ”Top 500” supercomputers is scrutinized using the metric. It is demons...

International supercomputer applications symposium

Although English has become the de-facto universal scientific language, this does not imply that there are no language barriers within the scientific community. On the contrary, people from different disciplines who are using the same tool-a supercomputer-to solve their problems, have great difficulty explaining to each other what exactly they are doing. On the other hand it can be very enlight...

Pipelining Computation and Optimization Strategies for Scaling GROMACS on the Sunway Many-Core Processor

The increasing gap between plentiful computing elements and limited memory bandwidth makes it increasingly difficult and sometimes even infeasible for HPC community to port more applications onto many-core processor archi‐ tectures. The Sunway many-core processor SW26010 used to build the Sunway TaihuLight System contains a total of 260 heterogeneous cores. All these cores can be divided into 4...

System Management in the BlueGene/L Supercomputer

The BlueGene/L supercomputer will use system-on-achip integration and a highly scalable cellular architecture to deliver 360 Teraflops of peak computing power. With 65,536 compute nodes, BlueGene/L represents a new level of scalability for parallel systems. As such, it is natural for many scalability challenges to arise. In this paper, we discuss challenges in the area of system management and ...
