Equalizer 1.4 released

7. September 2012


The last two weeks have been quiet, since I was on biking through Switzerland. Meanwhile, poor Daniel back at work churned through most of the Collage changes outlined in the last post. You can see the changes in the Collage endian branch on github, which will be merged back into master in the next couple of weeks.

Now back to the news: After finally figuring out how to build Equalizer and dependencies using MacPorts portfiles on Mac OS X, I released the long-standing 1.4 version of Equalizer, GPU-SD, Lunchbox and vmmlib. Below is the release announcement – enjoy!

Neuchatel, Switzerland – September 7, 2012 – Eyescale is pleased to announce the release of Equalizer 1.4.

Equalizer is the standard framework to create and deploy parallel, scalable 3D applications. This modular release includes Collage 0.6, a cross-platform C++ library for building heterogenous, distributed applications, GPU-SD 1.4, a C++ library and daemon for the discovery and announcement of graphics processing units using zeroconf networking and Lunchbox 1.4, a C++ library for multi-threaded programming. All software packages are available for free for commercial and non-commercial use under the LGPL open source license.

Equalizer 1.4 is a feature release extending the 1.0 API, introducing major new features, most notably asynchronous readbacks, region of interest and thread affinity for increased performance during scalable rendering. It culminates over seven years of development and decades of experience into a feature-rich, high-performance and mature parallel rendering framework and related high-performance C++ libraries.

Equalizer enables software developers to easily build interactive and scalable visualization applications, which optimally combine multiple graphics cards, processors and computers to scale the rendering performance, visual quality and display size.

Equalizer Applications

Eyescale provides software consulting and development services for parallel 3D visualization software and GPU computing applications, based on the Eyescale software products or other open and closed source solutions.

Please check the release notes on the Equalizer website for a comprehensive list of new features, enhancements, optimizations and bug fixes. A paperback book of the Programming and User Guide is available.

We would like to thank all individuals and parties who have contributed to the development of Equalizer 1.4.

Introducing Collage: github

3. August 2012

Collage

Collage Dependencies

Good news, everybody: Since this week, Collage is a separate project on github.

First this means that it’s much more lightweight to use since it has a small source code and repository size (<10MB) and less dependencies compared to the full Equalizer project. Say hello fast compilation times (less than a minute on my slowish laptop), easy setup and simpler directory layout.

Second this means that the next version will have a well-defined, stable API, similar to what Equalizer already has. I’m steadily working toward this with good progress and lots of cleanup. This means that building and maintaining distributed applications based on Collage will be painless.

Third and last my hope is that this gives the project more visibility and credibility, and therefore more outside contributions. We’ve already had quite a few awesome ones in the past, such as InfiniBand RDMA and UDT support.
