|
% PARALLEL CONTEXT
|
|
% In a parallel context, this function is used to check the cluster defined by the user.
|
|
% If no error happen the function returns 0. The function complies with
|
|
% Windows/Linux operating systems and Matlab/Octave software.
|
|
%
|
|
%
|
|
% INPUT/OUTPUT description:
|
|
%
|
|
%
|
|
% DataInput
|
|
% is the strcture option_.parallel, with the follow fields:
|
|
%
|
|
% Local 1 is on local machine, 0 remote
|
|
% ComputerName the computer name.
|
|
% CPUnbr the CPU's
|
|
% UserName the user name for the ComputerName.
|
|
% Password the password for the user name in ComputerName.
|
|
% RemoteDrive Drive used for Remote computation (data exchange, etc): must be contain 'RemoteFolder'.
|
|
% RemoteDirectory Folder in RemoteDrive used for Remote computation.
|
|
% MatlabOctavePath Path to MATLAB or Octave executable.
|
|
% DynarePath Path to matlab directory within the Dynare installation directory.
|
|
%
|
|
% This information is typed by the user in the DYNARE configuration file and is parsed by the preprocessor,
|
|
% the goal of this function is to check if configuration is correct and if dynare
|
|
% can be executed successfully in parallel mode.
|
|
%
|
|
%
|
|
% DataInputAdd
|
|
% it is the structure options_.parallel_info. Currently , only the string in the
|
|
% field RemoteTmpFolder (the temporary directory created/destroyed on remote
|
|
% computer) is used.

% table is below.
|

%
|
|
%
|
|
% Table for ErrorCode Values.
|
|
%
|
|
% ErrorCode -> 0 Initial Value -> No Error Detected!!!
|
|
% ErrorCode -> 1 ... When an error is detected, the values 1, 2, 3... are
|
|
% used to specify the type of error or warning.
|
|
%
|
|
% Value 1: The variable 'Local' has a bad value!
|
|
%
|
|
% Value 2: The variable 'CPUnbr' has a bad value. For more information
|
|
% see http://www.dynare.org/DynareWiki/ParallelDynare.
|
|
% 2.1 [warning] The user asks to use more CPU's than those available.
|
|
% 2.2 [warning] There are unused CPU's!
|
|
%
|
|
%
|
|
% Value 3: The remote computer is unreachable!!!
|
|
%
|
|
% Value 4: The fields user name and/or password are/is empty!
|
|
%
|
|
% Value 5: Remote Drive and/or Remote Folder do not exist!
|
|
%
|
|
% Value 6: It is impossible write/read files on the remote computer.
|
|
%
|
|
% Value 7: The values user and/or passwd are incorrect or the user has
|
|
% no permissions to execute a Matlab session. Or simply
|
|
% Matlab path (MatlabOctavePath) is incorrect!
|
|
%
|
|
% Value 8: Dynare path (DynarePath) is incorrect!
|

%
|
|
% Value 9: It is impossible delete remote computational temporary files!
|

%
|

%
|
