User-friendly and reliable grid computing based on imperfect middleware
Rob V. van Nieuwpoort, Thilo Kielmann, Henri E. Bal · 2007
Writing grid applications is hard. First, interfaces to existing grid middleware often are too low-level for application programmers who are domain experts rather than computer scientists. Second, grid APIs tend to evolve too quickly for applications to follow. Third, failures and configuration incompatibilities require applications to use different solutions to the same problem, depending on the actual sites in use.
