This note describes ParallelKnoppix, a bootable CD that allows creationof a Linux cluster in very little time.An experienced user can create a cluster ready to execute MPI programsin less than 10 minutes.The computers used may be heterogeneous machines, of the IA-32 architecture.When the cluster...

PelicanHPC is a rapid (around 5 minutes, when you know what you're doing) means of setting up a high performance computing (HPC) cluster for parallel computing using MPI. This tutorial gives a basic description of what PelicanHPC does,  addresses how to use the released CD images to set up a...

This note shows how to set up a Linux cluster for MPI parallel processing using ParallelKnoppix, a bootable CD.

The parameterized expectations algorithm (PEA) involves a long simulationand a nonlinear least squares (NLS) fit, both embedded in a loop. Both steps are natural candidates for parallelization.This note shows that parallelization can lead to important speedups forthe PEA.I provide example code...

The two main alternative methods used to identify key sectors within the input- output approach, the Classical Multiplier method (CMM) and the Hypothetical Extraction method (HEM), are formally and empirically compared in this paper. Our findings indicate that the main distinction between the...

We show how to calibrate CES production and utility functions when indirect taxation affecting inputs and consumption is present. These calibrated functions can then be used in computable general equilibrium models. Taxation modifies the standard calibration procedures since any taxed good has...

It is common to find in experimental data persistent oscillations in the aggregate outcomes and high levels of heterogeneity in individual behavior. Furthermore, it is not unusual to find significant deviations from aggregate Nash equilibrium predictions. In this paper, we employ an evolutionary...

The model we discuss in this note is a re-examination of the classical Bertrand model of imperfect competition. the main difference is that consumers are allowed to have some strategic behavior when deciding from which one of the two sellers to buy. We will approach the resolution of the...

Identifying key sectors or key locations in an interconnected economy is of paramount importance for improving policy planning and directing economic strategy. Hence the relevance of categorizing them and hence the corresponding need of evaluating their potential synergies in terms of their...
