An der FH Kärnten starten wir im Wintersemester 2018/19 den neun Studienzweig Multimediatechnik (Studiengang Informationstechnologien).
Der Studienzweig Multimediatechnik beschäftigt sich mit der Erstellung, Aufbereitung und Bearbeitung von Audio/Video Assets für professionelle Projekte für Kino, TV oder für die Werbebranche. Die Grundlagen und Konzepte von modernen Hard- und Software-Lösungen für die Aufnahme, Weiterverarbeitung und Wiedergabe von Audio-/Video- Produktionen stehen ebenso am Studienplan wie Grundlagen des Gamedevelopments bzw. die Entwicklung von Augmented und Virtual Reality Applikationen.
Der Studienzweig Multimediatechnik zeichnet sich weiters durch eine enge Kooperation mit Firmen aus dem Gamedevelopment und dem Bereich der Audio-/Video-Produktion aus. Dadurch wird den Studierenden bereits im Studium die Möglichkeit geboten, mit Professionisten zusammen an Projekten zu arbeiten.
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.
We at CUAS switched last year our main Homepage from Typo3 4.2 -> 6.2.x. After stabilizing our content and going live we noticed a 3-5 second delay on every action taken on the Backend. I’ve enabled caching stuff, switched the caching to memcached and did all things to accelerate Typo3. But the 3-5 second delay keeps.
Yeasterday I decided that a last effort should be made to determine the problem that leads to the delay. I set up PHP profiling on our live system an recorded some backend actions.
According to the profile logs our delay problem happens in the “fluidcontent” extension (4.3.3) which builds up some wizard tab content. In this prozess fluidcontent also checks if some other extensions which are providing templates have some icons setup.
The problem occurs in “/fluidcontent/Classes/Service/ConfigurationService.php”. There is a function “buildWizardTabItem” which is called thousend times generating Icons.
My workaround to this behaviour is to disable “getIconForTemplate” and “createIcon” method call.
Just add a “_” to the method test part.
if (TRUE === method_exists(‘FluidTYPO3\\Flux\\Utility\\MiscellaneousUtility’, ‘getIconForTemplate_’)) {
and
if (TRUE === method_exists(‘FluidTYPO3\\Flux\\Utility\\MiscellaneousUtility’, ‘createIcon_’)) {
This fixes our delay to < 1s 🙂 , the drawback is that you end with standard icons in the corresponding fluid modules.
Another important part is the relation of idle and busy workers.
Apache amount and relation of busy/idle workers
Here we see that in this particular case we have an average ratio 10/2 (idle/busy) and our max is about (11/7) which gives a balanced amount of idle and busy workers.
