pload

Load file into parallel session

Syntax

pload(fileroot)

Arguments

fileroot Part of filename common to all saved files being loaded.

Description

pload(fileroot) loads the data from the files named [fileroot

num2str(labindex)] into the workers running a communicating job. The files should

have been created by the psave command. The number of workers should be the same

as the number of files. The files should be accessible to all the workers. Any codistributed

arrays are reconstructed by this function. If fileroot contains an extension, the

character representation of the labindex will be inserted before the extension. Thus,

pload('abc') attempts to load the file abc1.mat on worker 1, abc2.mat on worker 2,

and so on.

Examples

Create three variables — one replicated, one variant, and one codistributed. Then save

the data. (This example works in a communicating job or in pmode, but not in a parfor

or spmd block.)

D = eye(numlabs,codistributor());

psave('threeThings');
