Using workstations efficiently: distributing computing power with workstations paves the way for concurrent engineering with high productivity

Article Abstract:

Grumman Aerospace Corp's Aircraft Systems Div is developing a distributed, data-driven computing environment, the Grumman Computer/Information Integrated Enterprise (CIE), that facilitates use of concurrent engineering for more rapid system development with higher product quality. The division had to integrate several design operations running different computer-aided engineering (CAE), computer-aided design (CAD), computer-aided manufacturing (CAM) and related software tools on a wide range of hardware from a Cray supercomputer to microcomputers, all with different operating systems. Grumman is basing CIE on an Ethernet- and TCP/IP protocol-based local area network that integrates previous computing resources and newly acquired IBM RS6000 workstations. The new workstations host such CAE and CAD/CAM packages as Cadam and Catia in the shared-data distributed environment. Advantages of the workstation strategy include more resources per user, greater reliability, cost-effect security, development of larger models without affecting other users and easier redistribution of resources as needed.

Distributing Among Micros

Article Abstract:

The distributed real-time multiprocessor (DRM) from NV Philips is made up of hardware machines (HAMAs) and software machines (SOMAs). A HAMA consists of a 68000 32-bit processor, memory, and input-output hardware. The many HAMA modules are linked by SOMAs which consist of one or more applications and input-output programs.

Running Motors Efficiently

Article Abstract:

Using Intel 8048 microprocessors, the Advanced Technology Group of Chesebrough-Pond's has designed controllers to vary power supplies to 60-cycle electric motors. The controllers monitor the loads on the motors and change the power along with changing loads. This allows the motors to run at their most efficient rates.
