A solution to get the problem off, have you found it? Really? What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the nonparametric smoothing and lack of fit tests is one(More)
<italic>This paper examines the problem of data placement in Bubba, a highly-parallel system for data-intensive applications being developed at MCC. &#8220;Highly-parallel&#8221; implies that load balancing is a critical performance issue. &#8220;Data-intensive&#8221; means data is so large that operations should be executed where the data resides. As a(More)
<italic>In dataflow architectures, each dataflow operation is typically executed on a single physical node. We are concerned with distributed data-intensive systems, in which each base (i.e., persistent) set of data has been declustered over many physical nodes to achieve load balancing. Because of large base set size, each operation is executed where the(More)

A new method is proposed for implementing an adaptive state space filter. This method is based upon the matrix minimum principle of optimal control theory. The adaptive state space filter is a two part algorithm. The first part is a recursive algorithm for optimizing a predictor matrix which describes the transformation from past data to future data.

Performance modeling and analysis of computer systems are often ignored during the project design phase in favor of other techniques collectively known as structured design or software engineering. We describe benefits that can result from including performance analysis as an integral part of the design process. Several different goals, time frames, and(More)
