pctRunOnAll
Run command on client and all workers in parallel pool
Syntax
pctRunOnAll command
Description
pctRunOnAll command
runs the specifiedcommand
on all the workers of the parallel pool as well as the client, and prints any command-line output back to the client Command Window. The specifiedcommand
runs in the base workspace of the workers and does not have any return variables. This is useful if there are setup changes that need to be performed on all the workers and the client.
Note
If you usepctRunOnAll
to run a command such asaddpath
in a mixed-platform environment, it can generate a warning on the client while executing properly on the workers. For example, if your workers are all running on Linux®operating systems and your client is running on a Microsoft®Windows®operating system, anaddpath
argument with Linux-based paths will warn on the Windows-based client.
Examples
Clear all loaded functions on all workers:
pctRunOnAllclear功能
Change the directory on all workers to the project directory:
pctRunOnAllcd/opt/projects/c1456
Add some directories to the paths of all the workers:
pctRunOnAlladdpath({'/usr/share/path1' '/usr/share/path2'})
Limitations
pctRunOnAll
does not support thread-based pools, such as those created byparpool("threads")
andbackgroundPool
