PetaSIM Motivation
PetaSIM was designed to allow “qualitative” (good enough) performance estimates” where in particular the design of machine is particularly easy to change
- motivated by (quite painful) process of comparison of very disparate architectures in Petaflop meetings
The project will build up a suite of benchmark applications which can be used in future activities such as “Petaflop” architectures studies
Applications are to be derived “by hand” or by automatic generation from Maryland Application Emulators
Special attention to support of hierarchical memory machines and data intensive applications
Support parallelism and representation at different grain sizes
Support simulation of “pure data-parallel” and composition of linked loosely synchronous data parallel modules
