ROPE: The Rutgers Online Proxy Evaluator
نویسندگان
چکیده
The Simultaneous Proxy Evaluation (SPE) architecture provides one way to measure the performance of proxy caches. It includes the novel ability to compare prefetching proxy cache performance, but poses a number of implementation challenges. In this report we describe our prototype implementation of SPE, the Rutgers Online Proxy Evaluator (ROPE). We discuss a number of issues raised during development, describe validation tests, and demonstrate the use of our prototype in two experiments to simultaneously evaluate up to four publicly available proxy cache implementations. We measure bandwidth used and response latencies, but also discover unexpected caching bugs in two of the proxies tested.

Preliminary Report on a Self-Applicable Online Partial Evaluator for Flowchart
This is a preliminary report on a self-applicable online partial evaluator for a flowchart language with recursive calls. Self-application of the partial evaluator yields generating extensions that are as efficient as those reported in the literature for offline partial evaluation. This result is remarkable because partial evaluation folklore has indicated that online partial evaluation techniq...
متن کاملForensic assessment of illness falsification, Munchausen by proxy, and factitious disorder, NOS.
The purpose of this article is to propose guidelines for the evaluation of possible Munchausen by proxy child abuse for the court systems. These assessments require the evaluator to have an understanding of the complexity involved when this type of abuse is alleged. The evaluator should have an appreciation of how falsification of illness may or may not occur, recognize the need for careful ana...
متن کاملTutorial on Online Partial Evaluation
This paper is a short tutorial introduction to online partial evaluation. We show how to write a simple online partial evaluator for a simple, pure, first-order, functional programming language. In particular, we show that the partial evaluator can be derived as a variation on a compositionally defined interpreter. We demonstrate the use of the resulting partial evaluator for program optimizati...
متن کاملThe Generation of a Higher-Order Online Partial Evaluator
We address the problem of generating an online partial evaluator for a higher-order, functional language from an appropriate interpreter using a state-of-the-art ooine partial evaluator. To ensure termination of the generated online spe-cializer the interpreter computes a self-embedding property on closure values and data structures. This guarantees termination whenever there is no static loop ...
