In Paderborn, the PLUS library has been developed. When it comes to graphical configuration tools, that help you with setting up the metacomputer for your applications, Laforenza mentions as an example, of course, WAMM developed at his own institution in Pisa. Job scheduling software is available from several companies, including the Germany based Genias Software, that offers the Codine system. A number of projects in Europe target at building a metacomputer, either for special purposes or as a general environment. Unicore is a large German project that is aimed to link the major German supercomputer centres into a single metacomputing environment.
Much attention is paid to user management, account management, security and file transfer.
A user does not need more than web access to submit jobs to a Unicore computing server. Laforenza is rather optimistic that the World Wide Web could provide the physical basis for metacomputing in the future, although there are many issues to solve.
