Command window output of still running task
显示 更早的评论
Hello,
does anyone whether there is a way to get the command window output of a task while it is still running?
If not, is there another built-in way of monitoring running tasks (besides the state?)?
Thanks,
Pieter

Start the session from another process, using OS-level pipe() to communicate with it. Unfortunately MATLAB does not flush its buffer at any particular time.
If you need graphics, you might have to read the output using screen capture techniques.
There is no mechanism within MATLAB to do what you would like (unfortunately.)

I just posted a question and i thought this is somewhat relevant to my question. I will appreciate any help
"Is it possible to check the whole history of a program which has let say i=20000 iteration. I have tried to debug the code but everything works fine till i=200 but i can't go till 20000.
The thing is when the program finishes, i can only see last couple of hundred iterations.
Is there anyway,i can check the whole program iteration(other than debugging)"
Cheers.

Hi Pieter,
Starting in R2012b it is now possible to get the diary output of a task while it is still running. See http://www.mathworks.com/help/distcomp/release-notes.html.
Cheers, Tom

nobody explains how to use it. Therefore, there's still no way of doing so.

Here are some examples of how you might do this:
If you are using a batch job to run your task, then you can use the diary() function passing in the job while it is still running e.g.
job = batch('myScript');
diary(job)
If you are using jobs and tasks, you must set the CaptureDiary flag on the task to true, and then query the Diary property of the task e.g.
myCluster = parcluster;
job = createJob(myCluster);
task = createTask(job, @myFunction, 0, {}, 'CaptureDiary', true);
submit(job);
task.Diary
