Introduction

This page will contain weekly targets and Updates about the work done.

Community Bonding Period

(23rd April to 18th May)

• Got familiar with the modules and database schema from previous repository.

• Had a discussion with H.S. Rai(Project Mentor) about the infrastructure to be used. We settled on Django as a web framework for the project.

• Learnt Django by reading through books and building a couple of small applications with it.

• Set up the development repository on Github.

• Discussed about the deployment options on BRL-CAD servers. It already has Python and MySQL support, and since we manage it ourselves, it would be easy install new packages on it.

• Fixed a few bugs to get the database and parser portions fully working. The benchmark logs can now be parsed and indexed into the database from the command line.

• Built a Django app with jquery to support file uploads that let's users(Link to the code is here):
  • Upload Benchmark logs
  • Does validation checks
  • allows the admin to view a list of files.

Development Phase

Week 1 (19th-25th May)

• 19th May(Monday): Started working on the plots app. Integrated the legacy database from previous repo with the models in the plots app.

• 20th May(Tuesday):' Continued the work with plots app, integrated both the databases(fileupload and benchmark) to a single database. Read the Django documentation on views and templates to refresh and understand a few details. Updated url mappings, and a simple admin interface for plots app.

• 21st May(Wednesday): I went through the tutorials on Highcharts and emulated a few examples. Created simple bar and line charts to understand the concept of series, axes and how the data is loaded via AJAX.

• 22nd May(Thursday): I decided to JSON as the data source for plots. This would require me to pass JSOn objects from view to templates. I went through the json module of python, particularly json.dumps and json.encode functions which will help in parsing JSON. I also thought about the types of plots I could generate from our app.

• 23rd May(Friday): Brainstormed over the visualizations I should work on, referred to suryajith's work on this and had a look at Openbenchmarking.org. After a discussion on the mailing list, we were able to arrive at a preliminary set of plots I should work on. Fixed a bug in the database connection file. Also got in touch with Sean regarding a server account.

• 24th May(Saturday): Half day of work. I created some charts using AJAX and a JSON file with initial data with the Highcharts library, had a few hiccups along the way. Next step is to refine these prototypes and integrate with the Django application.

Week 2

• 26th May(Monday): Did a comparison of various charting frameworks as Rai Sir had asked for. Also mentioned the reasons of choosing the HighCharts library. Further experimentation with HighCharts,I am able to load the series and chart options dynamically now. The url configurations have been modified to provide appropriate mapping for the charts and their data. Threw a couple of stub views which now I have to worked on. Cleaned up the fileupload app which was a mess of useless JS files.

• 27th May(Tuesday):

• Forked the repository to BRL-CAD's Github organisation, subsequent development will take place there. The new home for the repository is: https://github.com/BRL-CAD/benchmark
• Wrote the Django template file for charts. This contains the chart config and the JS script to make AJAX calls for JSON data. (https://github.com/BRL-CAD/benchmark/blob/master/plots/templates/chart.html)
• Started work on plots/data.py: The script which will return the aggregated data from database in the form of a dictionary. Wrote the aggregation codes for Avg VGR vs Processor Graphs, other plots should follow this structure. (https://github.com/BRL-CAD/benchmark/blob/master/plots/data.py)
• Wrote the rawdata view in plots/views.py that dumps JSON string after invoking the appropriate data aggregation function from data.py

• 28th May(Wednesday): Resolved a bug which prevented sending AJAX requests for the raw data in form of a JSON string in Django. Added support for two more plots, Average VGR Rating vs Number of Cores and Average VGR Rating vs OS Type. Made the chart template dynamic so that we don't have to change it depending on the plot. Added doc strings to views and data files.

• 29th May(Thursday): Added support for 4 more plots: Logarithmic VGR Rating vs Processor Family, Logarithmic VGR Rating vs OS Type, Logarithmic VGR Rating vs Number of Cores ,Running Time vs Processor Family. Spent some time resolving a bug in Django ORM.

• 30th May(Friday): Another plot supported now, the Absolute Rays per sec against Reference Images plot is up. Also added the options to export chart in form of a PDF, or an image.
