A number of codes for semide nite programming SDP are already available in cluding Why introduce yet another code for SDP CSDP is written in C for e ciency and portability The code is designed to make use of highly optimized linear algebra routines from the LINPACK or LAPACK libraries CSDP is distributed with version of the necessary LINPACK routines that have been translated into C The package...

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...

Combinations of C++ features, like inheritance, templates, and class nesting, allow for the expression of powerful component patterns. In particular, research has demonstrated that, using C++ mixin classes, one can express layered component-based designs concisely with efficient implementations. In this paper, we discuss pragmatic issues related to component-based programming using C++ mixins. ...

ClassdescMP is a distributed memory parallel programming system for use with C++ and MPI. It uses the Classdesc reflection system to ease the task of building complicated messages to be sent between processes. It doesn’t hide the underlying MPI API, so it is an augmentation of MPI capabilities. Users can still call standard MPI function calls if needed for performance reasons. 1 Classdesc Refle...

A lot of applications executed on distributed memory parallel computers can be classi-ed as data parallel applications, in which parallel operations on data elements are performed in a loosely synchronous manner. However implementation of such applications is still diicult. This paper presents an object-oriented approach for an easy and eecient data parallel programming in C++. More exactly, an...

PANDA is a run-time package based on a very small operating system kernel which supports distributed applications written in C++. It provides powerful abstractions such as very efficient user-level threads, a uniform global address space, object and thread mobility, garbage collection, and persistent objects. The paper discusses the design rationales underlying the PANDA system. The fundamental...

We have developed and deployed several web-based tutors for C++ programming concepts. We have been remotely collecting usage data from these tutors, and analyzing them for the benefit of the students, the teachers and ourselves. In this paper, we will describe the tutors, the types of data collected, and the types of analysis we perform on the data for the benefit of the various constituencies ...
