Re: Running batch octave jobs via webserver?

[George Kousiouris]

Hi,

we have released a service-based implementation of octave for 
incorporating octave-created models in service oriented infrastructures 
like Grids or clouds. Now, this solution is not finalized yet, however a 
first version is available at:
http://irmosproject.eu/Service_Engineering.aspx (it is the Mapping 
Service package)

Most important features are the paper describing the approach:
http://irmosproject.eu/Files/MappingService_Conference_presentation.pdf 
and http://www.computer.org/portal/web/csdl/doi/10.1109/SCC.2010.37

and the source code:
http://irmosserviceeng.svn.sourceforge.net/viewvc/irmosserviceeng/trunk/Mapping/src/

Now this is not exactly what you are looking for given that in this 
approach we had a specific model that was run for performance estimation 
purposes. However if you take a look at the code, it uses an ftp server 
in order to obtain some necessary files. I guess you can modify it so 
that the user uploads through the web page his script to the ftp server 
and then this replaces the createmodel.sh script (which in turn invokes 
a createmodel.m octave script).

On the other hand, it has solved some difficult problems like having a 
stable execution of Octave threads through java for as long as needed 
(the time out periods are configured in the client and server and can be 
set to whatever interval, without the computer hanging after some time 
or the calls time out). Furthermore, in the related work of the paper as 
far as i can remember some other solutions are mentioned which are 
probably closer to what you look for (user submitted scripts on an 
octave server).

This is just a preliminary version of the code, we plan to update it in 
the next months with some modifications (bug fixing, RESTful 
implementation etc.)

Hope it helps,
George
