function fParallel(fblck,nblck,whoiam,ThisMatlab,fname)
|
|
% PARALLEL CONTEXT
|
|
% In a parallel context, this function is launched on slave
|
|
% machines, and acts as a wrapper around the function containing the
|
|
% computing task itself.
|
|
%
|
|
% INPUTS
|
|
% o fblck [int] index number of the first thread to run in this
|
|
% MATLAB instance
|
|
% o nblck [int] number of threads to run in this
|
|
% MATLAB instance
|
|
% 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
|
|
% (entry in options_.parallel)
|
|
% o fname [string] function to be run, containing the computing task
|
|
%
|
|
% OUTPUTS
|
|
% None
