....tasks. This background load is adapted as the number and the load of the foreground tasks change, to keep the overall load equal to that of the originally measured system. For this, they have implemented a measurement and job generation module within the UNIX kernel. Kao and Iyer describe in [7] their design of a user oriented synthetic workload generator that is to be used for simulation of user file access behavior. User oriented, as opposite to system oriented, means that the workload represents the behavior of one user and not the behavior of the whole system. The remainder of this ....

....for studying the performance of concurrent programs (using simulation) This approach is rather static, in that the user has no ability to experiment with different parameters to modify the synthetic workload. An attempt towards a useroriented synthetic workload generation is presented in [Kao 92] and [Roge 93] for the analysis of distributed systems. In this work, we propose synthetic workload generation for parallel systems as a general method which expediently produces a synthetic workload specified by the user rather than performing a single generalized experiment with static and or ....

....same array location is constantly accessed, yielding a cache hit rate of practically 100 . A stride of 4 bytes (which is the size of a single S2 cache line) will force a cache hit rate of almost 0 . The number of memory accesses can be controlled. I O An I O based workload generator developed in [31] is used. Using a synthetically generated file system, the I O generator initiates I O requests, which are handled by the UNIX operating system. The I O requests are made in a logical sequence (e.g. a file must be opened before it can be closed) and an attempt is made to model an actual I O ....

.... workload generators follow this paradigm[13] They are quite adequate for certain performance evaluation problems in computer systems, such as in evaluating alternative implementations of file systems, where it can be assumed that the file access patterns of a user are implementation independent [7] [4] Another example is in the evaluation and refinement of virtual memory algorithms using traces of memory references. Once again, memory access patterns of programs can be assumed to be independent of (say) the particular cache coherence protocol being evaluated. Such generators are, ....

....After selecting the type of workload model and the level of characterization, the parameters that will build up the workload model are to be identified and quantified. The parameters can be quantified either in terms of total (mean) values or in terms of distributions (measure of variability) Kao 92] The selected parameters can either be obtained from analysis or execution of the application program itself, from its specification, from a typical benchmark or from execution traces (measurements) We will develop an approach, were the model parameters are derived from the description of the ....

....evaluation of computer systems where there is no feedback from the mechanism or policy being evaluated to the experimentation environment. For example, in evaluating alternative implementations of file systems, it can be assumed that the file access patterns of a user are implementationindependent [23, 44, 93]. Another example is in the evaluation and refinement of virtual memory algorithms using traces of memory references. Once again, the memory access patterns of programs can be assumed to be independent of (say) the particular cache coherence protocol being evaluated. Figure 12 shows the schematic ....

....workload does not necessarily have to produce any useful computational results. Executable models include instruction mixes, kernels, synthetic scripts or programs, interactive drivers, or traces. In literature, several approaches can be found on approaches [Bart 92] Lind 92] and tools [Mehr 92] Kao 92] Roge 93] for executable , artificial workload generation for parallel systems. In some workload generators, the workload parameters are adjustable to mimic for example computation or communication intensive applications, or particular memory access patterns and frequencies. In performance ....
