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
