Marshalling our power

The train marshalling problem

The problem considered in this paper arose in connection with the rearrangement of railroad cars in China. In terms of sequences the problem reads as follows: contains all the elements of S p(1) , then all elements of S p(2) , : : :, etc., and nally all elements of S p(t). The aim of this paper is to show that the decision problem: \Given numbers n; k and a partition S of f1; 2; :::; ng, is K (...

Profile Guided Code Optimisation of Marshalling Routines

The marshalling operation has often been identified as a performance bottleneck for high-speed network applications. In this paper, we propose the use of profile guided code generation of marshalling routines in order to better adapt performance optimisations of marshalling routines to the requirements of a specific application. We motivate this approach with a detailed case study and measureme...

Marshalling in Distributed Systems: Two Approaches

In general, modern computer systems are distributed systems. Such systems are implemented as computer networks, whose components jointly use and exchange data. To describe distributed systems at abstract level client-server model can be used. In terms of this model, client makes invocation, containing all necessary parameters, on server. Server receives the invocation, performs needed actions a...

RBSIM- simulation model of marshalling yard operation

This paper deals with a simulation model of technological procedures in a marshalling yard. The structure of the model and its properties are described from the point of view of a user. Attention is paid namely to its flexibility and built in capacities of cooperative solution of problems during the simulation run.
