Sorting is one of the most basic algorithms, and developing highly parallel sorting programs becoming increasingly important in high-performance computing because number CPU cores per node modern supercomputers tends to increase. In this study, we have implemented two multi-threaded algorithms based on samplesort compared their performance supercomputer Fugaku. The first algorithm divides an in...

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 ...

Understanding how proteins fold is an important step in uncovering the mysteries of protein function. To date, the computational resources needed to simulate even the shortest and simplest protein folds have been astronomical. Simulation of larger and more complex folds has been prohibitively expensive. In 1999, IBM announced the start of an effort to build a supercomputer, the BlueGene, to be ...

The quantum nature of phenomena dominating the behaviour of nanostructures raises new challenges when trying to predict and understand the physical behaviour of these systems. Addressing this challenge is imperative in view of the continuous reduction of device sizes, which is rapidly approaching the atomic level. Since even the most advanced experimental observations are subject to being funda...
