This volume, the definitive reference manual for the latest version of MPI-1, contains a complete specification of the MPI Standard.Since its release in summer 1994, the Message Passing Interface (MPI) specification has become a standard for message-

Shared, multiuser, workstation networks are characterized by unpredictable variability in system load. Further, the concept of workstationownershipis typically present. For efficient and unobtrusive computing in such environments, applications must n

Arrays that are distributed in a block-cyclic fashion are important for many applications in the computational sciences since they often lead to parallel algorithms with good load balancing properties. We consider the problem of redistributing such a

We introduce a meta-heuristic to combine simulated annealing with local search methods for CO problems. This new class of Markov chains leads to significantly more powerful optimization methods that wither simulated annealing or local search. The mai

Many large-scale engineering and scientific calculations involve repaired updating of variables on an unstructured mesh. To do these types of computations on distributed memory parallel computers, it is necessary to partition the mesh among the proce

Class-specific optimizations are compiler optimizations specified by the class implementor to the compiler. They allow the compiler to take advantage of the semantics of the particular class so as to produce better code. Optimizations of interest inc

We consider a new class of optimization heuristics which combine local searches with stochastic sampling methods, allowing one to iterate local optimization heuristics. We have tested this on the Euclidean Traveling Salesman Problem, improving 3-opt

This paper describes an approach to supporting efficient processor virtualization and dynamic load balancing for message-based, parallel programs. Specifically, a user-level process package (UPVM) for SPMD-style PVM applications is presented. UPVM su
