A growing trend in the development and deployment of grid computing systems is decentralization. Decentralizing these systems helps make the more scalable and robust, but poses several challenges. In this paper we address one such problem - that of locating computing resources meeting specified requirements in a large scale heterogeneous system. The(More)
Program profiling can help performance prediction and compiler optimization. This paper describes the initial work behind TFP, a new profiling strategy that can gather and verify a range of flow-specific information at runtime. While TFP can collect more refined information than block, edge or path profiling, it is only 5.75% slower than a very fast runtime(More)
Overlapping communication with computation is a well-known technique to increase application performance. While it is commonly assumed that communication and computation can be overlapped at no cost, in reality they interfere with each other. In this paper we empirically evaluate the interference rate of communication on computation via measurements on a(More)
