In this talk, we briefly survey some general aspects of metacomputing: hardware, system and administration issues, as well as the application field. Next we identify some algorithmic issues and software challenges that must be solved to efficiently program and/or transparently use such platforms:
We illustrate each of these issues and challenges by the analysis of several case studies:
Cluster ScaLAPACK, AppLeS, Globus, Legion, Albatross and Netsolve.
We conclude this talk by stating some final remarks and recommendations.
