The book contains a course in the broad field of "high-performance computing", intended for students, graduate or post doctoral from universities and vocational high schools and for technical and research workers. The course is self contained but some global knowledge (e.g. of a high-level programming language) is assumed. The material can be used by lecturers in courses on computers, computer science or computational science, but can also be used by students directly without further guidance.

A number of contributions are made, including a new approach to matrix distribution, new insights into layering parallel linear algebra libraries, and the application of ``object based'' programming techniques which have recently become popular for (parallel) scientific libraries. We present an overview of a prototype library, the <bf> SL_Library </b>, which incorporates these ideas. Preliminary performance data shows this more application-centric approach to libraries does not necessarily adversely impact performance, compared to more traditional approaches.

This volume represents a thorough revision of "Fortran 90 Explained". It includes more detailed explanations of many features with more examples (giving about 18 additional pages), as well as new appendices (on avoiding Fortran 77 extensions and an extended pointer example, a further 12 pages). Also, it incorporates all the interpretations, and has a completely new chapter on Fortran 95 (18 pages). It is a complete and authoritive description of Fortran 90/95.

It is difficult to write programs which are both correct and efficient even for a single MIMD parallel architecture. A program which is efficient in execution on one member of this architecture class is often either not portable at all to different members of the architecture class, or if portability is possible, the efficiency attained is usually not satisfactory on any architecture.
The conceptual basis of the approach we have taken to providing a solution for the problem of programming MIMD parallel architectures is based upon raising the level of abstraction at which parallel program structures are expressed and moving to a compositional approach to programming. The CODE 2.0 model of parallel programming permits parallel programs to be created by composing basic units of computation and defining relationships among them. It expresses the communication and synchronization relationships of units of computation as abstract dependencies. Runtime determined communications structures can be expressed.
Ready access to these abstractions is provided by a flexible graphical interface in which the user can specify them in terms of extended directed graphs. Both ease of preparation of correct programs and compilation to efficient execution on multiple target architectures is enabled. The compositional approach to programming focuses the programmer's attention upon the structure of the program, rather than development of small unit transformations. In the CODE 2.0 system, the units of computation are prepared using conventional sequential programming languages along with declaratively specified conditions under which the unit is enabled for execution.
The system is built upon a unique object-oriented model of compilation in which communication and synchronization mechanisms are implemented by parameterized class templates which are used to custom tailor the translation of abstract specifications in communication and synchronization to efficient local models.
The attainment of the goals of the research is measured in the following ways. There have been several uses of the CODE 2.0 system by casual users in parallel programming classes. The results are uniformly positive; the programs which are developed are simple and easy to read, and execute at least as efficiently as programs written in conventional parallel languages. Experimental measurement of the execution behavior of benchmark programs has shown that the executable code generated by CODE 2.0 is efficient, often within 5% or less, and sometimes more efficient than hand-generated parallel programs. Portability with retention of efficiency of execution has been demonstrated by implementations on two different execution environments; an implementation on the synchronous message paradigm given by Ada and in the shared-memory environment of the Sequent Dynix operating system.
Designed to only with the MPICH implementation of MPI and has been tested with versions V1.0.10 through V1.0.13 It also requires Tcl and Tk. it has been tested with Tcl7.3/Tk3.6, Tcl7.4/Tk4.0 and and Tcl 7.5/Tk 4.1 and works best with a colour display.
