Pipeline system for Octave and Matlab News

PSOM 1.0 released

Pierre Bellec — Thu, 13 Dec 2012 3:42:16 GMT

After over a year of test, it is finally time to release PSOM 1.0. This is a stable, production release that includes all of the features planned on the initial roadmap (and a few more).

New logo

PSOM has new logo, that was designed to avoid any confusion between PSOM and a popular (although rather old) video game.

PSOM paper published

Pierre Bellec — Wed, 04 Apr 2012 1:59:17 GMT

There is now a published paper providing an overview of PSOM features and implementations:
Bellec P, Lavoie-Courchesne S, Dickinson P, Lerch JP, Zijdenbos AP and Evans AC (2012) The pipeline system for Octave and Matlab (PSOM): a lightweight scripting framework and execution engine for scientific workflows. Front. Neuroinform. 6:7. doi: 10.3389/fninf.2012.00007

PSOM release 0.9

Pierre Bellec — Thu, 01 Dec 2011 3:49:30 GMT

PSOM r0.9 had just been released and can be downloaded from here:
http://www.nitrc.org/frs/?group_id=316

This is the PSOM candidate release, with all the features planned for PSOM 1.0 available. A paper of PSOM has also been submitted for publication, with a detailed description of the PSOM design and implementation. This will be made avaiable on the PSOM website upon acceptance. If you are using PSOM and find it useful, it is now an excellent time to show your support by filling in an evaluation on the NITRC website:

The main changes since PSOM 0.8.8 are:
* The PSOM has now been tested on a variety of operating systems (Linux, Windows, Mac OSX), with both Matlab and Octave and with different configurations. So far, the only issue that was found was the 'background'/'batch' modes for Octave on Cygwin (Windows).
* A new function PSOM_CONFIG. It will test step-by-step that the submission of jobs is successful, and provide context-dependent error messages and suggestions if an issue is detected. This function should help a lot setting up the configuration of PSOM.
* A new wiki page providing [http://code.google.com/p/psom/wiki/CodingGuidelines coding guidelines] for PSOM users.
* A new execution mode : 'background'. In this mode jobs run in the background, and they will get interrupted if the initial matlab/octave session is interrupted (which is not the case in 'batch' mode). The default mode is now 'session' for the pipeline manager, and 'background' for the jobs.
* The [http://code.google.com/p/psom/wiki/ConfigurationPsom PSOM configuration tutorial] has been updated to reflect the changes made in release 0.9.
* The [http://code.google.com/p/psom/wiki/HowToUsePsom PSOM tutorial] has been updated to match the reflect made to `psom_demo_pipeline` in release 0.9.
* Many minor bug fixes and improvements.
A more detailed list of changes can be found in the [http://code.google.com/p/psom/wiki/ReleaseNotes release notes].

PSOM release 0.8.8

Pierre Bellec — Mon, 17 Jan 2011 8:30:07 GMT

A minor upgrade to speed up the initialization phase of the pipeline and the submission of jobs.
This release corresponds to the version 491 of the subversion repository :
* There is a new function PSOM_STRUCT_DEFAULTS which can be used to set the default values of fields in a structure. This method is much faster than PSOM_SET_DEFAULTS which upload fields as variables in memory. This last practice is anyway discouraged by the Mathworks. This new function will thus become the standard method to set default arguments in the development framework.
* A bunch of small modifs that speed up the pipeline initialization and manager big time. Even more improvement is to be expected soon, but PSOM_RUN_PIPELINE is already much smoother now.

PSOM release 0.8.6

Pierre Bellec — Tue, 23 Nov 2010 10:17:58 GMT

Main new features :
* The search path can now be configured with '' to use the current search path, 'gb_psom_omitted' to make no attempt to change the search path (the start-up search path will apply), or any string to explicitly set up the search path. This can be set up through GB_PSOM_PATH_SEARCH in the file PSOM_GB_VARS.M
* It is now possible to create a file PSOM_GB_VARS_LOCAL.M anywhere in matlab/octave search path, and this file will override the default configurations found in PSOM_GB_VARS.M

PSOM release 0.8.5

Pierre Bellec — Wed, 26 May 2010 2:27:34 GMT

PSOM 0.8.5 has just been released. The main new features are :
* Removing the lock file in the log folder will now kill the pipeline manager, in any execution mode.
* The random number generator is now initialized based on the clock for each job, while before it was using the default state (in matlab this state is identical for every session).

Creation of the PSOM repository in NITRC

Pierre Bellec — Tue, 12 Jan 2010 6:36:40 GMT

PSOM has just been registered in NITRC. It is still going to be hosted by google code in the future (http://code.google.com/p/psom/), but the activity of the project should be updated on NITRC as well. Eventually the plan is to use the forum and mailing list at NITRC.
