Performance evaluation on grids: directions, issues, and open problems

Grids are semantically different from other distributed systems. Therefore, performance analysis, just like any other technique requires careful reconsideration. We analyse the fundamental differences between grids and other systems and point out the special requirements raised to performance analysis. The main aim is to survey the special problems, the possible directions and the existing solutions. A monitoring system, that is able to support the posed requirements is introduced as an example.
