....includes costly semantics (e.g. the assumption of wholly separate memories) that are often not required on parallel systems with a globally addressable memory. In an attempt to provide a simpler, more efficient, and portable approach to running programs on shared memory architectures, OpenMP [25,26] has been proposed as a standard. OpenMP is a specification for a set of compiler directives, library routines, and environment variables that can be used to specify shared memory parallelism in Fortran and C C programs. Although a Beowulf type commodity cluster as a whole does not fit the ....

....should be able, at run time, to make use of the services offered by other parallel programs. High level parallel programming frameworks for shared memory computers are available mainly for facilitating the development of computational applications and for ensuring the portability of programs [3][4]. In addition, software distributed shared memory systems exist which provide a global shared address space on top of physically distributed memory computers [5] In the present contribution, we focus on distributed memory systems and try to create abstractions which rely purely on the ....

....are mostly found in applications divided into several threads where at one point it must be assured that all threads reach a certain state and do not proceed until indeed all threads have arrived at their designated locations. Only then each thread continues its operation. Some APIs such as OpenMP [2] embed a barrier command into their language. In Concurrent Haskell, we can get this e#ect using a list of MVars. In contrast to a build in directive, we have to initialise the barrier with the number of threads that will later synchronise on it. While for the general case of barriers in ....

....hand, HPF does not allow the exploitation of control parallelism and in some cases (e.g. irregular computations) the compiler is not able to identify all the parallelism that can be exploited in a parallel program, and thus it does not generate efficient code for parallel architectures. OpenMP [58] is a library (application program interface or API) that supports parallel programming in shared memory parallel computers using the global data space approach. OpenMP has been developed by a consortium of vendors of parallel computers (DEC, HP, SGI, Sun, Intel, etc. with the aim to have a ....

Section 7 discusses related work. We conclude in Section 8. 2. BACKGROUND The OpenMP Application Program Interface (API) [20, 21] supports shared memory parallel programming in C C and Fortran programs. Current OpenMP implementations are limited to shared memory architectures. We have implemented the rst prototype of OpenMP on distributed memory machines, and in particular on a network of workstations (NOW) 19] We use ....

....distributed shared memory. 2 1 Introduction The OpenMP Application Programming Interface (API) is an emerging standard for parallel programming on shared memory multiprocessors. It de nes a set of program directives and a library for run time support that augment standard C, C and Fortran [19, 20]. In contrast to MPI [12] a message passing API, OpenMP facilitates an incremental approach to the parallelization of sequential programs: The programmer can add a parallelization directive to one loop or subroutine of the program at a time. Unlike POSIX threads [4] OpenMP speci cally addresses ....

Section 6 discusses related work. Section 7 summarizes our conclusions. 2 The OpenMP API The OpenMP API [19, 20] de nes a set of program directives that enable the user to annotate a sequential program to indicate how it should be executed in parallel. There are three kinds of directives: parallelism work sharing, data environment, and synchronization. In C and C , the directives are implemented as #pragma ....

OpenMP derives from the ANSI X3115 efforts. It is a set of compiler directives and runtime library routines that extend a sequential programming language to express parallelism with a shared memory.
