Concurrent constraint programming is classically based on asynchronous communication via a shared store. This paper presents new versions of the ask and tell primitives which features synchronicity. Our approach is based on the idea of telling new information just in the case that a concurrently running process is asking for it. The new primitives are shown to be simple yet expressive enough to...

In many concurrent programming languages programs are difficult to extend and modify. This is because changes in a concurrent program (either through modification or extension) require re-implementation of some or all components. This paper presents the design of a concurrent object-oriented programming language based upon separate specifications of computations and interactions of programs. Se...

CnC is a system for describing the structure of parallel computation, or coordinating the dataand control-flow between the individual steps of a computation [2, 3]. A CnC application specifies a set of discrete step functions, and the data collections used as input to and output from those step functions.1 The CnC coordination language describes the relationship between a specific invocation of...

In this paper, a language based on the notion of concurrent, communicating objects is presented. Each object executes a specification given in temporal logic and communicates with other objects using asynchronousbroadcast message-passing. In contrast to the notions of predicates as processes and stream parallelism seen in concurrent logic languages, Concurrent METATEM represents a more course-g...

We present an extension to Haskell which supports reactive, concurrent programming with objects, sans the problematic blocking input. We give a semantics together with a number of programming examples, and show an implementation based on a preprocessor, and a library written in Concurrent Haskell.

The assignment of resources or tasks to prbcessors in a distributed or parallel system needs to be done in a fashion that helps to balance the load and scales to large configurations. In an architectural model that distinguishes between local and remote data access, it is important to base these allocation functions on a mechanism that preserves locality and avoids high-latency remote reference...

patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...

C++ and Concurrent C are both upward-compatible supersets of C that respectively provide dataabstraction and parallel programming facilities. Although data abstraction facilities are important forwriting concurrent programs, we did not provide data abstraction facilities in Concurrent C because we didnot want to duplicate the C++ research effort. Instead, we decided that we would ev...
