Resource discovery in a grid environment is a critical problem, as a typical grid system includes a very large number of resources which must be readily identified and accessed to run applications. This paper presents a time-to-live based multi-resources reservation algorithm on resource discovery in grid environment, which enables the sharing, selection,(More)
The knapsack problem is a famous NP-complete problem. It is very important in the research on cryptosystem and number theory. After its proposed parallel algorithms are analyzed deeply, a new parallel algorithm by sampling is proposed based on MIMD supercomputers in the paper. Then performance analysis and comparisons are illuminated. Finally the(More)
