....was determined to give the desired value of s for a slice , including overheads such as for the RPC. Loading and running an experiment The set of processes needs to be loaded and run on the target network. For this one could use a script, or a system like PVM. We used a program called DECALS [11] that was previously developed to run performance experiments in a distributed heterogeneous enviroment. DECALS provides facilities for the automatic launching of experiment sets, including synchronized startup and shutdown, and initialization of the task templates via parameter files. As well, ....

If the competing workload utilization is known the analytic model can be adjusted to account for it. 4 6 8 10 12 14 16 18 20 22 24 1 2 3 4 5 6 7 8 9 10 Number of User Tasks Case 1 Case 2 measured predicted Figure 4. Systems 1 and 2. 11 5. Experiments with Two Server Layers Instead of just replicating the servers in the second layer we may also be able to divide each service into a front end part and a back end part, with the latter implemented in a deeper layer of servers. This divides the service load further and ....

....detailed simulations, or the production system. We have implemented it in several environments: a functional prototyping environment (MLOG [16] a commercial prototyping environment (ObjecTime [36] a distributed software system simulator called Parasol [34] coarse grained UNIX tasks [27], and in the DCE RPC environment [37] using data collected by the POET debugger [49] We concentrate here on traces produced by a design prototype environment, namely ObjecTime. There are several benefits to using TLC as opposed to a source code examination approach for constructing models. ....

Many uses for the temporal relation have already been established: ....
