Data Flow Modules and PetaSIM II
One or more Client Server Applications are a special case of Dataflow
- Application servers in industry are moving client server to dataflow
Can be applied either to a geographically distributed network or to a cluster of PC’s or workstations
In PetaSIM, need to define “middle-tier” objects and their performance parameters and “simple estimates” as in PetaSIM fits the coarse graining of applications
General problem is multiple “dataflow graphs” and collaborative sessions to be modeled in context of a given network model
- MSTAR (as in Darpa Performance Program) is Dataflow (Khoros)
