Embedded high performance computing is being called upon to provide critical computing resources with increasing frequency. The ability to tolerate faults during operation, both maintaining operational capability and ensuring that correct results continue to be produced, is an important ingredient in mission-critical systems. An architecture for such a system is proposed, providing the ability to...
MPI has emerged as a popular way to write architecture-independent parallel programs. By modifying an MPI library and associated MPI run-time environment, transparent extraction of timestamped information is possible. The wall-clock time at which specific MPI communication events begin and end can be recorded, collected, and provided to a central scheduler. The infrastructure to create and collect...
This paper describes the human immune system and its functionalities from a computational viewpoint. The objective of this paper is to provide the biological basis for an artificial immune system. This paper will also serve to illustrate how a biological system can be studied and how inferences can be drawn from its operation that can be exploited in intelligent agents. Functionalities of the biological...
Demand for embedded environmental sensors is increasing. One of the key sensor capabilities is the ability to measure salinity. In addition to understanding the environment, a salinity measurement is needed to estimate water density and to convert pressure to estimates of water depth. This outlines a low-cost sensor that combines an H-bridge and digital potentiometer to make an AC resistance measurement...
