AMD and the open-source community are writing history

Over the last few years, AMD has slowly been walking the path towards having fully open source drivers on Linux. AMD did not walk alone, they got help from Red Hat, SUSE, and probably others. Phoronix also mentions PathScale, but I have been told on Freenode channel #radeon this is not the case and found no trace of their involvement.

AMD finally publically unveiled the GPUOpen initiative on the 15th of December 2015. The story was covered on AnandTech, Maximum PC, Ars Technica, Softpedia, and others. For the open-source community that follows the development of Linux graphics and computing stack, this announcement comes as hardly surprising: Alex Deucher and Jammy Zhou presented plans regarding amdgpu on XDC2015 in September 2015. Regardless, public announcement in mainstream media proves that AMD is serious about GPUOpen.

I believe GPUOpen is the best chance we will get in this decade to open up the driver and software stacks in the graphics and computing industry. I will outline the reasons for my optimism below. As for the history behind open-source drivers for ATi/AMD GPUs, I suggest the well-written reminiscence on Phoronix.

On having leverage and using it for pushing open-source software adoption

Back in late August and early September, I attended 4th CP2K Tutorial organized by CECAM in Zürich. I had the pleasure of meeting Joost VandeVondele's Nanoscale Simulations group at ETHZ and working with them on improving CP2K. It was both fun and productive; we overhauled the wiki homepage and introduced acronyms page, among other things. During a coffee break, there was a discussion on the JPCL viewpoint that speaks against open-source quantum chemistry software, which I countered in the previous blog post.

But there is a story from the workshop which somehow remained untold, and I wanted to tell it at some point. One of the attendants, Valérie Vaissier, told me how she used proprietary quantum chemistry software during her Ph.D.; if I recall correctly, it was Gaussian. Eventually, she decided to learn CP2K and made the switch. She liked CP2K better than the proprietary software package because it is available free of charge, the reported bugs get fixed quicker, and the group of developers behind it is very enthusiastic about their work and open to outsiders who want to join the development.

What is the price of open-source fear, uncertainty, and doubt?

The Journal of Physical Chemistry Letters (JPCL), published by American Chemical Society, recently put out two Viewpoints discussing open-source software:

  1. Open Source and Open Data Should Be Standard Practices by J. Daniel Gezelter, and
  2. What Is the Price of Open-Source Software? by Anna I. Krylov, John M. Herbert, Filipp Furche, Martin Head-Gordon, Peter J. Knowles, Roland Lindh, Frederick R. Manby, Peter Pulay, Chris-Kriton Skylaris, and Hans-Joachim Werner.

Viewpoints are not detailed reviews of the topic, but instead, present the author's view on the state-of-the-art of a particular field.

The first of two articles stands for open source and open data. The article describes Quantum Chemical Program Exchange (QCPE), which was used in the 1980s and 1990s for the exchange of quantum chemistry codes between researchers and is roughly equivalent to the modern-day GitHub. The second of two articles questions the open-source software development practice, advocating the usage and development of proprietary software. I will dissect and counter some of the key points from the second article below.

Joys and pains of interdisciplinary research

In 2012 University of Rijeka became NVIDIA GPU Education Center (back then it was called CUDA Teaching Center). For non-techies: NVIDIA is a company producing graphical processors (GPUs), the computer chips that draw 3D graphics in games and the effects in modern movies. In the last couple of years, NVIDIA and other manufacturers allowed the usage of GPUs for general computations, so one can use them to do really fast multiplication of large matrices, finding paths in graphs, and other mathematical operations.

Last week in Rijeka we held Science festival 2015. This is the (hopefully not unlucky) 13th instance of the festival that started in 2003. Popular science events were organized in 18 cities in Croatia.

I was invited to give a popular lecture at the University departments open day, which is a part of the festival. This is the second time in a row that I got invited to give popular lecture at the open day. In 2014 I talked about The Perfect Storm in information technology caused by the fall of economy during 2008-2012 Great Recession and the simultaneous rise of low-cost, high-value open-source solutions. Open source completely changed the landscape of information technology in just a few years.
