function fParallel(fblck,nblck,whoiam,ThisMatlab,fname)
|
|
% In a parallelization context, this function is launched on slave
|
|
% machines, and acts as a wrapper around the function containing the
|
|
% computing task itself.

%
|
|
% INPUTS
|
|
% fblck [int] index number of the first thread to run in this
|
|
% MATLAB instance
|
|
% nblck [int] index number of the first thread to run in this
|
|
% MATLAB instance
|
|
% whoiam [int] index number of this CPU among all CPUs in the
|
|
% cluster
|
|
% ThisMatlab [int] index number of this slave machine in the cluster
|
|
% (entry in options_.parallel)
|
|
% fname [string] function to be run, containing the computing task
