Graph copying is used in parallel implementations of functional languages on architectures with distributed memory. This paper will explore the costs of graph copying in detail. It will make clear that these costs can form a bottleneck for a class of serious parallel programs. This not only comprises practical divide and conquer style programs of which parallel matrix multiplication is an examp...

In an ideal e-business environment, when a customer order is scheduled and a ship date is computed, the availability should immediately be reserved and not be available for future orders. However, in reality the availability data that are used for the scheduling the orders are not real time availability (physical availability), but they are availability information stored in an IT system (syste...

As the cost of hardware continues to fall, IT projects still experience budget overruns, which in some cases result in the abandonment of the projects. It could be argued that a lack of understanding of the indirect costs associated with IT/IS investments is a major contributor towards this phenomenon. This paper presents findings from an exploratory study that aimed at investigating the level ...
