/parallel/environments/mpi/unify/reports/Message-Passing/zipcode_parcomp.ps.Z: The Design and Evolution of Zipcode by Anthony Skjellum, Computer Science Department & NSF Engineering Research Center for Computational Field Simulation,Mississippi State University; Steven G. Smith, Numerical Mathematics Group, Lawrence Livermore National Laboratory; Nathan E. Doss, NSF Engineering Research Center for Computational Field Simulation, Mississippi State University; Alvin P. Leung, Northeast Parallel Architectures Center, Syracuse University and Manfred Morari, Chemical Engineering, California Institute of Technology. March 8, 1994 ABSTRACT: Zipcode is a message-passing and process-management system that was designed for multicomputers and homogeneous networks of computers in order to support libraries and large-scale multicomputer software. The system has evolved significantly over the last five years, based on our experiences and identified needs. Features of Zipcode that were originally unique to it, were its simultaneous support of static process groups, communication contexts, and virtual topologies, forming the "mailer" data structure. Point-to-point and collective operations reference the underlying group, and use contexts to avoid mixing up messages. Recently, we have added "gather-send" and "receive-scatter" semantics, based on persistent Zipcode "invoices," both as a means to simplify message passing, and as a means to reveal more potential runtime optimizations. Key features in Zipcode appear in the forthcoming MPI standard.
/parallel/environments/mpi/unify/reports/Message-Passing/zipcode_pvm.ps.Z: Integrating Zipcode and PVM: Towards a Higher-Level Message-Passing Environment by Li-wei H. Lehman, NSF Engineering Research Center for Computational Field Simulation, Mississippi State University, Mississippi State, Mississippi, 39762, USA. December 10, 1993. ABSTRACT: This paper describes the architecture and implementation of an integrated message-passing environment consisting of Zipcode and PVM. Zipcode is a highlevel message-passing system for multicomputers and homogeneous networks of computers. PVM is a relatively low-level message-passing system designed for multicomputers and heterogeneous networks of computers. Although PVM provides a workable and easyto-use message-passing system, it does not have some of the high-level constructs, such as communication contexts, required to develop reliable and scalable parallel libraries and large-scale distributed software. By porting Zipcode's high-level constructs on top of PVM, the integrated environment facilitates existing PVM applications to gradually migrate from a low-level to a high-level message-passing paradigm. In the integrated environment described here, Zipcode is ported on top of PVM via an intermediate layer, the emulated Cosmic Environment/Reactive Kernel (CE/RK) layer. Such an integrated environment allows programmers to utilize high-level Zipcode constructs as well as low-level PVM calls. Implementation details of the CE/RK primitives are presented. Planned future enhancements include performance improvement of the integrated system as well as adding heterogeneous environment support.

/parallel/applications/genetic-algorithms/stanford-report: Parallel Genetic Programming on a Network of Transputers by John R. Koza and David Andre, Stanford University. See ftp://elib.stanford.edu/pub/reports/cs/tr/95/1542/ ABSTRACT: This report describes the parallel implementation of genetic programming in the C programming language using a PC 486 type computer (running Windows) acting as a host and a network of transputers acting as processing nodes. Using this approach, researchers of genetic algorithms and genetic programming can acquire computing power that is intermediate between the power of currently available workstations and that of supercomputers at a cost that is intermediate between the two. A comparison is made of the computational effort required to solve the problem of symbolic regression of the Boolean even-5-parity function with different migration rates. Genetic programming required the least computational effort with an 8% migration rate. Moreover, this computational effort was less than that required for solving the problem with a serial computer and a panmictic population of the same size. That is, apart from the nearly linear speed-up in executing a fixed amount of code inherent in the parallel implementation of genetic programming, parallelization delivered more than linear speed-up in solving the problem using genetic programming.

/parallel/environments/mpi/unify/reports/Message-Passing/Elros_paper1_26mar94.ps.Z: Collective Operations Using ELROS and Sockets by Kishore Viswanathan and Anthony Skjellum ABSTRACT: ELROS, an acronym for Embedded Language for Remote Operation Services, was developed at LLNL for programming distributed applications. ELROS statements can be embedded in a conventional language such as C. This makes it easier to develop distributed applications. ELROC supports both synchronous and asynchronous operations. ELROC also provides a good exception handling facility. Although ELROS provides a good programming interface, it does not provide primitives for collective operations. In this paper we present some of the collective operations that were writting using ELROS. We also present programs to demonstrate how these operations can be implemented using sockets. Advantages and disadvantages of using ELROS over sockets are also discussed.
