SUMMARY:Accelerate MMEwald on a New Generation of Sunway Supercomputer
DESCRIPTION:Workshop\n\nAccelerate MMEwald on a New Generation of Sunway S
 upercomputer\n\nWu, Wu, Shang, Liu, Cui...\n\nThe Poisson solver for the c
 alculation of the electrostatic potential is an essential primitive in qua
 ntum mechanics calculations. In this paper, we adopt the Ewald method and 
 propose a highly-optimized and scalable framework for Poisson solver, MMEw
 ald, on the new generation Sunway supercomputer, capable of utilizing the 
 collection of 390-core accelerators it is equipped with. The MMEwald is ba
 sed on a grid adapted cut-plane approach to partition the points into batc
 hes and distribute the batch to the processors. Furthermore, we propose a 
 set of architecture-specific optimizations to efficiently utilize the memo
 ry bandwidth and computation capacity of the supercomputer.\n\nTag: Online
