Syntax

Arguments

Description

folder = getAttachedFilesFolder returns a string, which is the path to the local folder into which AttachedFiles are written on the worker. This function returns an empty array if it is not called on a MATLAB^® worker.

folder = getAttachedFilesFolder(FileName) returns the path name to the specified attached folder on the worker, or the folder containing the specified attached file. FileName can match either the full name of the attached file or folder, or on the ending part of the name. Multiple match results return a cell array.

If you have attached a folder, this does not match on file names within that folder.

Suppose you attach the folder 'C:\monday\tuesday\wednesday\thursday', which on the workers is stored in /tmp/MDCS/tp12345. The following table displays the results of various match attempts.

Examples

Attach a folder to a parallel pool, then find its location on the worker to execute one of its files.

myPool = parpool;
addAttachedFiles(myPool,'mydir');
spmd
    folder = getAttachedFilesFolder('mydir');
    oldFolder = cd(folder);  % Change to that folder
    [OK,output] = system('myExecutable');
    cd(oldFolder);           % Change to original folder
 end

Attach an executable file to a parallel pool, then change to its folder for accessing and processing some data.

myPool = parpool;
addAttachedFiles(myPool,'myExecutable');
spmd
    system('myExecutable');   % Now on MATLAB path
    folder = getAttachedFilesFolder('myExecutable');
    oldFolder = cd(folder);
    fid = open('myData.txt'); % Access data file
        % Process fid
    close(fid)
    cd(oldFolder);            % Change back to the original folder
end
