....query optimizer is built up in a strict modular way, as detailed in fig. 4. The transformation manager first catches up the optimal sequential execution plan from the EDBMS(first phase) It then applies a suite of local transformations to this plan, in order to find the best parallelized plan [BRU95a](second phase) For each operation of the plan, the transformation manager collaborates with the resource allocation manager, which optimizes the I O, CPU and memory consumption. Therefore, it determines a first set of calculators having enough memory and CPU power to execute the operation. It ....

....static optimization strategy requires to estimate unknown run time parameters such as the size of the intermediate relations, the deviation of the tuples partition. Erroneous estimations may strongly alter the efficiency of the chosen PEP, if no control mechanism is applied to query processing [4]. In a previous work [5] we proposed an ad hoc mechanism able to deal with unexpected situations. However the general optimization framework proposed above is particularly well suited to such control mechanisms. Indeed, suppose a supervisor process dynamically detects too big a difference between ....
