The european ESPRIT project STRETCH is dedicated to the management of documents by their content. We present in this paper the high-performance developments and the programming support required by STRETCH indexing and retrieval processes.
Large array processing can be done efficiently by a linear processor array. We developed a SIMD line-processor computer and a high-level programmation 's environment including a C-like Array Programming Language with Object-Oriented abilities in order to compute physical problems. We based our work on the problem of manipulation, high-level representation and machine-level mapping of data. We try...
In this paper, we show that both software and hardware must be organized around a hierarchy of communications to perform well on todays multiprocessor machines. We classify data into three cat- egories: the sedentary ones, the nomadic ones and the migrating ones.We show that the applications and the chips they are run on should concen- trate on communications involving mainly sedentary and nomadic...
