Maestro is a distributed shared memory system currently being developed. In this paper, an architecture of the high performance network interface of Maestro is presented. Maestro consists of multiple PC(Personal Computer)s and dedicated network hardware for high performance message passing and maintaining cache coherency. IEEE1394, a high performance serial link, is used in the physical layer o...

As high-speed, broadband networks replace slower, narrowband networks, multimedia applications are more widely used today than ever before. Distributed multimedia applications are, however, very difficult to develop and manage. This is mainly due to the lack of appropriate support in conventional operating systems. In order to solve this problem, we have developed an object-oriented distributed...

In this paper we present Maestro, a model-based systems engineering (MBSE) environment for design and simulation of complex electronic systems using Orchestra—a simulation tool developed at Sandia National Laboratories. Maestro is deployed as a plugin for MagicDraw and uses Orchestra domain-specific language (DSL) which is based on SysML. Maestro enables a model-based design and analysis approa...

This work aims to describe the composing style and aesthetics of Michelangelo Lupone, a leading figure in the Italian electroacoustic musical scene of the last twenty years. Starting from the description of choices made in writing Corda di Metallo (Metal String) for string quartet, synthesis and live electronics, the guidelines that accompanied the entire production by the composer born in Solo...

The I-Maestro project seeks to undertake research and a development in the field of Technology enhanced education within music. The authors as part of the project consortium are responsible for the accessibility aspects which come along with this; namely providing functionality to support accessible music formats such as Braille Music, Talking Music and large print music and also helping the co...

Most clusters so far have used WAN or LAN-based network products for communication due to their market availability. However, they do not always match communication patterns in clusters, thus incurring extra overhead. Based on our investigation for such overhead, we have optimized cluster communication at link layer. Partitioning each message in 16-byte packets, our optimization uses two techni...

This paper presents the Maestro Tools a distributed object layer built on top of the Ensemble group communication system developed at Cornell The Maestro tools include a visual application development environment an interface to and implementation of funda mental distributed object abstractions such as CSCW cooperative work client server and publish subscribe objects and a set of adaptive contr...

PTAEDA2 is a distance-dependent, individual tree model that simulates the growth and yield of a plantation of loblolly pine (Pinus taeda L.) on an annual basis. The MAESTRO model utilizes an array of trees in a stand to calculate and integrate the effects of biological and physical variables on the photosynthesis and respiration processes of a target tree on an hourly basis. PTAEDA2 sums the qu...

The evaluation of nonfunctional properties, specially power consumption, at early design phases is very important for making better design choices in the development of an embedded system. This extended abstract presents: a) MAESTRO [4], a system-level methodology for the modeling and evaluation of interdependent nonfunctional properties together with embedded firmware, OS services, and applica...

Microprocessor core counts are on a trajectory such that for many applications the microprocessor will soon be overprovisioned for computation with respect to off-chip communication and memory system capabilities. In the absence of strategies to exploit intra-chip communication, performance of even simple benchmarks is noticeably impacted by coscheduling multiple copies on the cores of current ...
