....faster CPUs, the portion of time for I O activities will increase further. A key issue in parallelization is how to create opportunities for concurrent accesses to the signature file, which resides on disks, without resorting to redundant storage. Current Frame Signature Files (CAT) proposed in [6], were shown to be able to solve the problem effectively. In the subsequent sections, we describe an implementation of a full text retrieval system based on CAT on a network of workstations. We present performance results from experiments to demonstrate the effectiveness of running such ....

....can be shortened because the overhead of scanning the signatures may be more than covered by reducing number of documents actually read. Compared to inverted file methods, signature file methods usually incur substantially smaller space overhead and it can handle insertions much more efficiently [6]. However, scanning the entire signature file could be intolerably slow except for a small database. Partitioning the signature file is necessary [5] to reduce the amount of data that need to be processed. Below, we describe a method that ffl partitions the signature files effectively, and it ....
