@inproceedings { , title = {Solving the Klein-Gordon equation using Fourier spectral methods: a benchmark test for computer performance}, abstract = {The cubic Klein-Gordon equation is a simple but non-trivial partial differential equation whose numerical solution has the main building blocks required for the solution of many other partial differential equations. In this study, the library 2DE-COMP\&FFT is used in a Fourier spectral scheme to solve the Klein-Gordon equation and strong scaling of the code is examined on thirteen different machines for a problem size of 512 3. The results are useful in assessing likely performance of other parallel fast Fourier transform based programs for solving partial differential equations. The problem is chosen to be large enough to solve on a workstation, yet also of interest to solve quickly on a supercomputer, in particular for parametric studies. Unlike the Linpack benchmark, a high ranking will not be obtained by simply building a bigger computer.}, conference = {HPC '15 Symposium on High Performance Computing}, isbn = {978-1-5108-0101-1}, note = {eStaffProfile Description: , eStaffProfile Brief Description of Type:}, pages = {182-191}, publicationstatus = {Published}, publisher = {Association for Computing Machinery (ACM)}, url = {https://nottingham-repository.worktribe.com/output/1126609}, year = {2015}, author = {Aseeri, S. and Batrašev, O. and Icardi, M. and Leu, B. and Liu, A. and Li, N. and Muite, B.K. and Müller, E. and Palen, B. and Quell, M. and Servat, H. and Sheth, P. and Speck, R. and Van Moer, M. and Vienne, J.} }
