As of today, I’ve added a shortcut ( https://hcm-lab.de/environs.git ) to clone the environs repository:
git clone https://hcm-lab.de/environs.git
The Environs framework has now been updated with specifications for the PortalInstance and PortalInfo objects.
https://hcm-lab.de/environs/howtos/tutorial-api-calls-and-notifications/portalinstance-objects/
The first part of a tutorial on howto conceptualize, design, and realize a simple chat application using the Environs framework has been written and published: -> ChatApp Tutorial
This may only of interesest to you if you’re a (n interaction) designer.. However, … first part done… :D
As of today, the project page of Environs got online and is well prepared for the EICS conference in Rome.
Environs was developed so as to enable research for my PhD thesis within. It enables simple and efficient implementations of distributed applications and user interfaces for multi display environments. Have a look at the project page http://hcm-lab.de/environs
As a sidenote to the recent post, the therein presented kernel is already superfast, but guess what :-)
There are ways to make it even faster by virtue of memory access optimizations. Let’s consider the memory access of U and V plane. They both access the same bits within the same dimension, thus can be consolidated into the same work item to access the memory only once (global memory access is the slowest memory access type).
Futhermore, “flattening” the work-group from 2D to 1D enables faster sequential memory access instead of the presented 2D access, hence benefit much better from prefetching and probably help avoiding bank conflicts…
So far for optimizations.. If there is demand on an appropriate kernel, then drop me an email..
