PARFOR Progress Monitor v2

This version is an update of the progress monitor made by Edric Ellis.

Description

Original version:
http://www.mathworks.com/matlabcentral/fileexchange/24594-parfor-progress-monitor

This version has a few additional settings:
- progress step size: for loops with a large number of iterations crash in Edric Ellis' implementation.
By setting the progress step size, for example to 1%, crashing of Matlab is prevented.
- width of the screen
- height of the screen

How to start?
In Matlab:
1) go to the directory where you saved the m file
2) change example.m if you want

In the command window:
3) enter matlabpool open
4) enter pctRunOnAll javaaddpath java
5) enter example

very useful in my parallel simulations! by the way, whenever you run parallel simulations where you don't know in advance the number of cycles of the parfor, it would be very useful to have a function to update the total number of cycles given at construction time...

[Edmondo]

it could be great to have also an estimated remaining time

Works perfectly in my application, which is a deployed parallel function.

When deploying a function using this progress monitor note that "pctRunOnAll javaaddpath java" will have no effect, you need to embed the folder containing the java classes into the CTF archive when you compile... then it runs like a charm :)

Thanks

I'll answer my own question. To get this to work on osx, you need to modify the matlab class to append '.local' to the hostname.

o.HostName = [cfg.hostname '.local'];

After figuring out I had to reduce "progressStepSize" for my needs - it really works!

[Stephen]

I get a "java.net.ConnectException: Connection refused" when I attempt to run this on OSX. Any advice?

Thanks

[Stephen]

I wonder if this could be enhanced with a button to cancel the jobs. For ex: place a button on the form that sets a variable and when updating the percent done on the jobs, it could return the signal to quit running.

Just a thought from someone who knows nothing about Java. :)

My previous comment is gone but this was in relation to monotoring progress when using nexted loops or events that occur more than once per parfor loop iteration. E.g.:
parfor i1=1:N1
for i2=1:N2
for i3=1:N3
%increase ppm here if mod(xx,..
end
end
end

Got it to work by setting an apropriate N size (N1*N2*N3), I didn't use xx but if the inner for loops are not parfor loops then counters can be used (i.e. something like xx=xx+1 for each inner iteration).
