For example, the NPAC kernel runtime is built on some of the technologies pioneered in the earlier packages. It is based on a common descriptor for distributed arrays, implemented in an object-oriented framework. The kernel library can be called from various languages (currently Fortran, C++ and Java) through language-specific interfaces. A separate package developed at Maryland supports interoperability between pre-existing libraries by allowing distributed arrays to be transferred seamlessly from one package to another. Other partners have developed run-time libraries for more specific problem areas.

Extractions: Parallel Programming Environments To implement a parallel algorithm you need to construct a parallel program. The environment within which parallel programs are constructed is called the parallel programming environment . Programming environments correspond roughly to languages and libraries, as the examples below illustrate for example, HPF is a set of extensions to Fortran 90 (a "parallel language", so to speak), while MPI is a library of function calls. There are hundreds of parallel programming environments. To understand them and organize them in a meaningful way, we need to sort them with regard to a classification scheme. In this note, we organize programming environments in terms of their core programming models. This is a complicated way to sort parallel programming environments, since a single programming environment can be classified under more than one programming model (for example, the Linda coordination language can be thought of in terms of a distributed-data-structure model or a coordination model). In this note, the classifications are given, and the programming environments in each class are described in general terms. We then give a very small sampling of the most important programming environments for each category.

Extractions: by Greg Astfalk C omputational concurrency is employed to reduce the time to solution of computationally demanding applications. Concurrency in this context means to perform on several processors at the same time those portions of the computations required for a single application that can be done independently. This definition excludes the simpler case of the throughput of multiple independent applications. In this three part series we discuss various approaches to concurrent programming of multiprocessor systems and we discuss the languages and the programming methodologies that are in common use. We also enumerate some pros and cons of the various approaches. Reasonably achieving the solution to today's demanding computational problems often exceeds the capabilities of a single processor. The concurrent use of multiple processors on a single problemparallel processing in today's vernacularhas the potential to overcome this shortfall. The programming task of coordinating multiple processors to solve a computational problem can be significantly more difficult than the equivalent programming for a single processor. It is the parallel programming issue that we discuss here. The complete endeavor of using a computer, parallel or sequential, to achieve a solution to a problem encompasses several steps, the major ones being:

Extractions: Lisp An interpreter language. Some implementations on UNIX(including Linux) are available: GCL An implementation of Lisp that used to be known as Kyoto Common Lisp (KCL). This generates C code which is compiled with the local C compiler and it is intended to eventually support the ANSI standard for Common Lisp. http://sunsite.unc.edu/pub/Linux/Incoming/ Common Lisp http://sunsite.unc.edu/pub/Linux/devel/lang/lisp/ Sather Sather is an object oriented language which designed to be simple, efficient, safe, and non-proprietary. It aims to meet the needs of modern research groups and to foster the development of a large, freely available, high-quality library of efficient well-written classes for a wide variety of computational tasks. It was originally based on Eiffel but now incorporates ideas and approaches from several languages. One way of placing it in the "space of languages" is to say that it attempts to be as efficient as C, C++, or Fortran, as elegant and safe as Eiffel or CLU, and to support higher-order functions as well as Common Lisp, Scheme, or Smalltalk.

Extractions: Cilk is a multithreaded programming language being developed at MIT. The Cilk language minimally extends C to allow programmers to specify the interactions among computational threads in a high-level fashion. Cilk's runtime system dynamically maps the computation onto available physical resources in a provably efficient fashion. The performance of a Cilk program is mathematically guaranteed to scale up linearly with the number of processors, as long as the application has sufficient parallelism and the architecture sufficient communication bandwidth. Moreover, Cilk provides a theoretical performance model based on ``Brent's theorem'' that allows a programmer to predict the performance of algorithms. Our implementation of Cilk is efficient: a parallel Cilk program ``scales down'' to run on a single processor with nearly the same efficiency as comparable C code, thereby removing a major barrier to parallel programming. In addition, Cilk provides a novel debugging tool called the ``Nondeterminator'' which guarantees to automatically find determinacy-race bugs in a parallel Cilk execution.

Extractions: Beowulf was the legendary sixth-century hero from a distant realm who freed the Danes of Heorot by destroying the oppressive monster Grendel. As a metaphor, ``Beowulf'' has been applied to a new strategy in high performance computing that exploits mass-market technologies to overcome the oppressive costs in time and money of super-computing [ Beowulf consists of a set of N Using a combination of switches, much larger configurations can be achieved on the order of a thousand nodes by connecting several routers in a tree structure. The total latency increase of such a big system is of less than a factor three. The most popular operating system on Beowulfs is Linux. A specific package based on Redhat called Extreme Linux is often used. A parallel software package is needed to use a Beowulf effectively. Examples are PVM (parallel virtual machine), MPI (message passing for interprocessor communication). Sterling et. al. [ ] use MPI. Since many groups already use a Beowulf new software appears, an example is CILK.
