Abstract: The GridRPC model [17] is an emerging standard promoted by the
Global Grid Forum (GGF) that defines how to perform remote client-server
computations on a distributed architecture. In this model data are sent back to
the client at the end of every computation. This implies unnecessary
communications when computed data are needed by an other server in further
computations. Since, communication time is sometimes the dominant cost of
remote computations, this cost has to be lowered. Several tools instantiate the
GridRPC model such as NetSolve developed at the University of Tennessee,
Knoxville, USA, and DIET developed at LIP laboratory, ENS Lyon, France. They
are usually called Network Enabled Servers (NES). In this paper, we present a
discussion of the data management solutions chosen for these two NES (NetSolve
and DIET) as well as experimental results.
