Lev Lafayette has an MBA (Technology Management) from the Chifley Business School, where he was on the Dean's List, a Graduate Certificate in Project Management from the same institution, and an honours degree from Murdoch University in Politics, Philosophy and Sociology which is commented upon by the Vice-Chancellor of the time. Many years later he completed a Graduate Certificate in Adult and Tertiary Education at the same institution.
He is a certified PRINCE2 Practioner, and an Adult and Workplace Trainer. Clearly not satisfied with one masters degree, he's started another, this time a Master of Education at the University of Otago. With a interdisciplinary approach, Lev's interests include the political implementation of universal pragmatics, the relationship between communications technology and society, and comparative economic systems. On again and off again, he plods his way through completing a PhD in Social Theory as well.
Professionally however, Lev is an experienced systems administrator, specialising in the Linux operating system and scientific applications, a project manager, systems engineer, and quality management systems coordinator, specifically for ISO 9001 (Quality assurance) and ISO 270001 (Information Technology Security). Previous employment and clients include several years working as a computer systems trainer and database management for the Parliamentary Labor Party in Victoria. Following this he worked for the Ministry of Foreign Affairs in Timor Leste (East Timor) managing their computer network and providing training and technical expertise to that Ministry in their first year of self-governance. Dr. Ramos-Horta provided the following comments on his work.
Lev works for the Victorian Partnership for Advanced Computing as a systems administrator for Linux clusters. As per that organisation, this site is mostly dedicated to issues concerning High Performance Computing, Scientific Computing and Supercomputing. Lev is involved in Linux Users of Victoria, having spent four years as President, two years as Public Officer, two years as Vice-President, a year as Treasurer and is now in his second years as an ordinary committee member.
The crocodile logo was designed by Victoria Jankowski. It was first used on the cover of Neon-komputadór, the first IT training manual for the Ministry of Foreign Affairs in East Timor which was printed and translated by the United Nations Development Programme. The crocodile represents the Timorese people and is the emblem of their land. The integrated circuit represents their independent connectivity to the wider world.
You can also find a political site that Lev subscribes to, The Isocracy Network, a synthesis of several progressive political orientations, and RPG Review which covers his interests in roleplaying and simulation games. As a secular humanist with an interfaith perspective, he manages and contributes to the Lightbringers website. He also has a livejournal, which will probably be quite boring to anyone who doesn't know him personally.
That's enough of me talking about myself in the third person like Cerebus The Aardvark.

The use of cloud computing as an alternative implementation for high performance computing (HPC) initially seems to be appealing, especially to IT managers and to users who may find the jump from their desktop application to the command line interface challenging. However a careful and nuanced review of metrics should lead to a reconsideration of these assumptions.

The increasing size of datasets acts a critical issue for eResearch, especially given that they are expanding at a rate greater than improvements in desktop application speed, suggesting that HPC knowledge is requisite. However knowledge of such systems is not common.

Very much a minor update to the presentation I gave in 2013, this talk provides a definition of supercomputers, high performance computing, and parallel programming, their use and current metrics, the importance and dominance of the Linux operating system in these areas, as well as some practical hands-on examples.

NGINX has released an article entitled Adopting Microservices at Netflix: Lessons for Team and Process Design. For a high level article it reads well, but closer consideration suggests that it fraught with problems, not the least some rather simplistic panacea attitudes.

GNU Octave is a high-level language, primarily intended for numerical computations. It makes a very good alternative to MATLAB.

For those who love their system's
For those who love their system's
uptime it is a sad moment when a power outage causes your system to go down after months or years. Worse still, on a reboot, you discover that your time is out by a hour, courtesy of daylight's saving time. Which is fine in itself, but it would be a better world if we all just used UTC. But that's another argument.

"Big data" requires processing. Processing requires HPC. Increased processing results in increased research output. Research organisations that do not increase HPC usage will fall behind. HPC requires either 'dumb down the interface or skill up the user'. Making "user friendly" interfaces may not be the right path to take as HPC use will always have a minimum level of complexity. Training courses that use andragogical technqiues correlate with increased HPC use.

Recently a simple statement of PRINCE2 governance structures was provided. From this it is possible to derive a checklist for project managers to tick off, just to make sure that everything is done. Please note that this checklist is tailored and combines some functions. For example, there is no Business Review Plan as it is argued that any sensible project should incorporate these into the Business Case and the Project Plan.
A simple graphic is provided to assist with this process
