Beowulf Raspberry Pi cluster project @FH Kärnten – Medical Engineering

For our data science and parallel computing projects at Medical Engineering we are working on a 5x Raspberry PI/Asus Tinker Node for our Beowulf cluster

The final Beowulf cluster will have 20 of this nodes with 5×20 Raspberry PI/Asus Tinker.

Currently we have 20 Raspberry PI 3B running at 1400MHz.

One of our next tasks will be the evalution of the Asus Tinker devices as a replacment option for our Raspberry PI 3B.

Ultimaker² hits FH-Kärnten – Degree Program Medical Engineering

Today we got our brand new 3D-Printer (Ultimaker²) on our department. 🙂
The first printing tests look very promising. Our first projekt will be the inmoov project link

Some Impressions of our last Brussels / Medica Trip 2012

Some impressions of our last trip to Brussels and the Medica fair situated in Dusseldorf, Germany.

Every year Mr. Hoffland and his current semester are visiting the Medica, one of the world’s largest medical trade fair.

Rankz – an innovative middleware for sports event ranking information distribution

In one of my last posts I wrote about a young company Rarebyte. The folks from Rarebyte are mainly focused in game development but they also have a great experience in building highly scalable middleware applications for sport timing respectively sport events.

They are named their product line Rankz.

Rankz is desigend for small to very large sports events with thousands of  athletes. Its purpose is to get detailed information about every aspect of a sport event in real time. It has already been successfully used at the

Rankz is also the central core layer in a student project called “IRONNET” (FH-Sportstiming) done by students from Network Engineering & Communication (NET) and is also the overall software basis used  by “FH Sportstiming” (NET).  An older version is also operated by Triangle Show & Sports Promotion Gmb.

The middleware uses spring core layer technologies which allows them to be highlight flexible. The data structures which specify the sport event can be entirely configured through XML. A full featured editor for XML/POJO  is also available. The interface to the timing database can also be configured through XML. For this reason you are neither limited by the used format of the timing data nor to the database engine. Rankz works out of the box with MySQL, PostgreSQL, Oracle, MSSql.

Furthermore Rankz uses a dynamic plugin system. So new features can be added very easily. Plugins can be loaded and unloaded @ runtime.

Features

  • Superfast – detailed results nearly live during a race
  • Support for plugins (input, output, calculations)
  • Platform independent (completely written in Java)
  • Integrated webserver (Jetty)
  • Plugins:
    • Overall ranking
    • Ranking per split
    • Ranking in athlete’s age group
    • Relative ranking at certain splits
    • Timing, average Speed, finishing context,….
    • statistic system and missed time error correction system
    • FTP plugin upload
    • Athlete’s (geographical) real time position prediction.
    • SMS/MMS Notification Service
    • Athlete’s@Twitter …
    • Virtual Athlete’s rankings (audience favorite….)
    • Position estimation
    • RESTful resource connectors
    • Webservice Revision Layer
    • Distributed mode for sport events like wingsforlife
  • Query engine
  • RESTful interface
  • Web output for all plugins
  • CSV exports for all plugins
  • Android/iPhone  (iOS) applications for live data/timing visualization (special version for Event Moderator/sport commentators).

Some impressions of my last iPod Touch 4gen broken fixing session.

This beast took me more than 4 hours to get the glass + digitizer emerged 🙂
