From Uno-Choice to Active Choices

15 May 2015 by Ioannis K. Moutsatsos

More than a year ago I approached Bruno via a series of posts on the BioUno developer’s forum and discussed my frustration with the available Jenkins user interface controls for generating advanced, dynamic user interfaces for scientific applications. I had seen partial implementations of what I thought we needed in some Jenkins plugins, but none of them was well maintained or provided in a single plugin the features I wanted. So, I asked Bruno whether it would be possible to create a new plugin with all of these features? He said ‘yes’ and he took on this challenge. One of Bruno’s first questions was ‘What should we call this new plugin?’. To credit the BioUno project contribution and my expectation that this UI plugin would make all the related incomplete plugins obsolete, I answered ‘Uno-Choice’, the one choice for all your needs!

In this blog entry, I will describe a bit of the Uno-Choice plugin history until its contribution to the Jenkins project with a new name, Active Choices Plugin.

Java DRMAA API — part 2

8 July 2014 by Bruno P. Kinoshita

This is the first part of a series of posts about a Java API for PBS servers, compliant with the DRMAA spec.

Java DRMAA API — part 1

This post could also be entitled “Why we won’t use DRMAA for our Jenkins plug-in”, with spoilers included. After working on a prototype DRMAA PBS Java library for a few days, I finally understand why we can’t use DRMAA v1 for the plug-in.

Consistent Reports for Data Analysis

7 July 2014 by Ioannis K. Moutsatsos

When you use Jenkins for analytics it is important to deliver consistent analysis reports from each build. There are a few different ways that you can create graphical, tabular and/or textual analysis reports, but one thing that becomes clear immediately is that you also require a certain level of dynamic behavior. Dynamic behavior is required so that you can easily adapt the reports to the underlying data whose format and content will likely change even when the same type of analysis is performed.

In this this blog entry, I will describe how I have used the Summary Display and Scriptler plugins to create a simple but effective framework for displaying consistent but dynamic reports following numerical data analysis using the R plugin.

Java DRMAA API — part 1

21 June 2014 by Bruno P. Kinoshita

This is the first part of a series of posts about a Java API for PBS servers, compliant with the DRMAA spec. PBS is a type of batch server, or distributed resource manager (DRM). It manages resources like CPU and memory in a network of computers, and is able to schedule jobs to run utilizing the maximum of these resources.

We have a PBS Plug-in for Jenkins, that enables us to submit and monitor jobs from Jenkins to a PBS server. James Hetherington proposed enhancements for the pbs-java-api and PBS Plug-in, including supporting other batch servers like SGE.

Experiences from JUC 2014 Boston

21 June 2014 by Ioannis K. Moutsatsos

On June 18th, I attended my first ever Jenkins User Conference in Boston, USA.

Not only I attended, but I also had the privilege to present at this meeting my work on:

Using Jenkins as a scientific data and image management platform

The meeting attracted more than 400 people, a quite impressive number of attendees. Most of these people were of course supporting the development operations of various companies, and they were clearly interested in what I call the standard Jenkins functionality and software build workflows. So, I was a bit pleasantly surprised when at least 150-200 people attended my talk which was clearly outside the primary interest of most attendees. Furthermore, at least 10 people remained after my talk to ask questions, discuss ideas, provide feedback and inquire how they could get a hold of the presentation slides.

If you review some of my final slides, you’ll see that I’m making some recommendations on the types of improvements required to make Jenkins a better platform for use by scientists. The BioUno project is making significant contributions in this area. Finally, note that my slides on the JUC 2014 CloudBees site are an earlier version of my presentation, and do not include some last minutes updates.
