Massively Parallel Computing: Unstructured Finite Element Simulations. Harvard Computer Science Group Technical Report TR-08-93.http://nrs.harvard.edu/urn-3:HUL.InstRepos:24826327Massively parallel computing holds the promise of extreme performance. Critical for achieving high performance is the ability to exploit locality of reference and effective management of the communication resources. This article describes two communication primitives and associated mapping strategies that have been used for several different unstructured, three-dimensional, finite element applications in computational fluid dynamics and structural mechanics.en-USResearch Paper or Report2016-01-21
