function slaveParallel(whoiam,ThisMatlab)
|
|
% PARALLEL CONTEXT
|
|
% In a parallelization context, this function is launched on slave
|
|
% machines, to initialize MATLAB and DYNARE environment and waits for
|
|
% instructions sent by the Master.
|
|
% This function is invoked by masterParallel only when the strategy (1),
|
|
% i.e. always open, is actived.
|
|
%
|
|
%
|
|
% INPUTS
|
|
% o whoiam [int] index number of this CPU among all CPUs in the
|
|
% cluster.
|
|
% o ThisMatlab [int] index number of this slave machine in the cluster.
|
|
%
|
|
% OUTPUTS
|
|
% None
