Relational Processor Experiments
Abstract
Our experiments with the Relational Processor have shown it to be a viable technology for use in Navy command and control systems. In particular, the DOSE scenario requires that approximately 45 tracks per second be processed. Based on the experiments with Ferranti's Relational Processor it should be able to handle a sustained rate of 590 to 2375 tracks per second depending on the ratio of updates to inserts as determined by the existing database. This performance is more than an order of magnitude greater than required; however, these numbers would have to be derated by the amount of query activity directed at the Relational Processor, for instance, by the DOSE graphics processor. While time did not permit measurements varying the number of attributes in a tuple, information obtained from the manufacturer indicates that the Relational Processor's performance appears to be more sensitive to the number of attributes than the number of tuples. All measurements in this experiment were made with the 17 DOSE attributes.
