Musings on Galaxy #1


The final frontier is here and its dressed up in a web framework for biomedical research named Galaxy. As we stand at the crossroads between 2012/2013 the world is more technologically orientated and biomedical research is no different. In genetics (something I am familiar with), common procedure for a genetics experiment  now contain no ‘wet-lab’ work. Data from publicly accessible databases adds up into the petabytes ( big guess! but its a lot) and there is still value in the data with many new discoveries lurking in the 1s and 0s.

XGrid --- The Grid of the Future / Past


XGrid is a cluster computing technology developed by Apple Inc. and up until Mac Os 10.7 (Lion) It comes shipped and supported on every Mac. This default installation is what has helped XGrid become so popular, unfortuantely as of 10.8 (Mountain Lion) Apple have stopped supporting XGrid and is no longer in active development, but don't let that stop you (More to come on that soon)! XGrid is possibly one of the easiest grid technologies to set up, maintain and put to use within minutes. As said earlier, XGrid is available on all Macs prior to Mac OS 10.8 and only requires a Mac OS X Server to host the controller. Once the controller has been set up, there is a simple XML file that needs to be enabled on each node (Agent in XGrid terminology) and that is it. Once they have been enabled and the controller correctly and easily configured, then a user (client) can submit jobs to the grid via the GUI, command-line, third-party GUIs (GridStuffer is excellent) or via many of the API's available (Objective-C, Java and Python to name a few).

A Sensor Observation Service for the NIWA climate database

The National Institute of Water and Atmospheric Research (NIWA) operates a network of weather and climate and other measurement stations, equipped with different sensors, observing a wide range of environmental properties – from temperature over rainfall to wind speed and directions.

Audio Geotagging Project



The main objective of this project is to design and develop an android tablet application for audio geo-tagging, which enables users to record where and when users touch a map display during an interview. Furthermore, the locational data will be automatically related to the time in the interview when an operation is performed on the map. Also, users are able to look up interviews by geographic queries such as keyword, time or location.

Reflections on the VIVO project


VIVO is a semantic web tool that allows interdisciplinary networking. My project aimed to explore the use of VIVO within NeSI as a means to both network researchers together for collaboration and also link them through common use of NeSI and its associated tools and software. This will facilitate increased productivity in all areas of research and in particular the sciences and information technology disciplines.

2012 New Zealand HPC Applications Workshop - Programme Released

The programme for the New Zealand HPC Applications Workshop has been finalised. A fantastic range of topics covering a wide range of uses of high performance computing in New Zealand. Climate science, machine learning, computational chemistry and many other domains and methods are well represented. There will be several talks on experiences parallelising code to many-core architectures and one focusing on how to make HPC more accessible.
