About Lev Lafayette

Crocodile Logo

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). He also does a lot of training for researchers and technical staff in Linux, High Performance Computing, mathematical programming, Postgresql, and related subjects, with graduates and post-doctoral researchers from a variety of organisations including: RMIT, La Trobe University, the University of Melbourne, Deakin University, Swinburne University, Victoria University of Technology, Monash University, the Australian Synchrotron, the Department of Environment and Primary Industries, the University of Sydney, Macquarie University, the University of New South Wales, the University of Western Australia, the Australian Institute of Health Innovation, the Westmead Millennium Institute, the Australian Radiation Protection and Nuclear Safety Agency, and the Australian Institution of Marine Science.

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 Research Platforms group at the University of Melbourne, and prior to that Victorian Partnership for Advanced Computing, as a systems administrator for Linux clusters. As per those roles, 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 third year as an ordinary committee member. He is has a coordinating role in the annual Multicore World conference and typically take the role of MC.

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.

HPC/Cloud Hybrids for Efficient Resource Allocation and Throughput

HPC systems running massively parallel jobs need a fairly static software operating environment running on bare metal hardware, a high speed interconnect to reach their full potential, and offer linear performance scaling for cleverly designed applications. Cloud computing, on the other hand, offers flexible virtual environments and can be used for pleasingly parallel workloads.

Multicore World 2017

The 6th Multicore World will be held on Monday 20th to Wednesday 22nd of February 2017 at Shed 6 on the Wellington (NZ) waterfront. Nicolás Erdödy (Open Parallel) has once again done an amazing job at finding some the significant speakers in the world in parallel programming and multicore systems to attend. Although a short - and not an enormous conference - the technical quality is always extremely high, dealing with some of the most fundamental problems and recent experiences in these fields.

OpenStack and the OpenStack Barcelona Summit

Presentation to Linux Users of Victoria, 7th February, 2017

An overview of cloud computing platforms in general, and OpenStack in particular, is provided introduces this presentation. Cloud computing is one of the most significant changes to IT infrastructure and employment in the past decade, with major corporate services (Amazon, Microsoft) gaining particular significance in the late 2000s. In mid-2010, Rackspace Hosting and NASA jointly launched an open-source cloud-software initiative known as OpenStack, with initial code coming from NASA's Nebula project and Rackspace's Cloud Files project, and soon gained prominence as the largest open-source cloud platform. Although a cross-platform service, it was quickly available on various Linux distributions including Debian, Ubuntu, SuSE (2011), and Red Hat (2012).

OpenStack is governed by the OpenStack Foundation, a non-profit corporate entity established in September 2012. Correlating with the release cycle of the product, OpenStack Summits are held every six months for developers, users and managers. The most recent Summit was held in Barcelona in late October 2016, with over 5000 attendees, almost 1000 organisations and companies, and 500 sessions, spread out over three days, plus one day of "Upstream University" prior to the main schedule, plus one day after the main schedule for contributor working parties. The presentation will cover the major announcements of the conference as well as a brief overview of the major streams, as well the direction of OpenStack as the November Sydney Summit approaches.

Career Opportunities

Had a friendly meeting a few days ago with a young person debating their future career path. They had a very good IT-orientated resume (give this person a job, seriously) but were debating whether they should go down the path of a Business Analyst. It was fairly clear that they lived and breathed IT, whereas the BA choice was one of some indifference. In reverse, there was a situation when VPAC had a year of summer school graduates where it became quickly obvious that none of them had any passion for IT.

Data Centre Preparation: A Summary

When installing a new system (whether HPC, cloud, or just a bunch of servers, disks, etc), they must be housed. Certainly this can be without any specialist environment, especially if one is building a small test cluster; for example with half-a-dozen old but homogeneous systems, each connected with 100BASE-TX ethernet to a switch etc.

Keeping The Build Directory in EasyBuild and Paraview Plugins

By default, EasyBuild will delete the build directory of an successful installation and will save failures of attempted installs for diagnostic purposes. In some cases however, one may want to save the build directory. This can be useful, for example, for diagnosis of *successful* builds. Another example is the installation of plugins for applications such as Paraview, which *require* access to the the successful buildir.

The Provision of HPC Resources to Top Universities

Recently, the University of Melbourne is ranked #1 in Australia and #33 in the world, according to the Times Higher Education World University Rankings of 2015-2016 [1]. The rankings are based on a balanced metric between citations, industry income, international outlook, research, and teaching.

Installing R with EasyBuild: Which path to insanity?

There is a wonderful Spanish idiom, "Cada loco con su tema" which is sometimes massacred as the English idiom "To each their own". In Spanish of course it is more accurately transliterated as "Each madman with their topic" which in familiar conversation means the same, has a slightly different and is a more illustrative angle on the subject. With the in mind, which path to insanity does one take with R libraries and EasyBuild? A similar question can also be raised with other languages that have extensions, e.g., Python and Perl.

High Performance Computing in Europe : A Selection

For about two weeks prior and a week after presenting at the OpenStack Summit in Barcelona I had the opportunity to visit several of Europe's major high performance computing facilities, giving each a bit of a standard pitch for the HPC-Cloud hybrid system we had developed at the University of Melbourne.
