• Dec 16, 2010: PHP.next: Traits – Presentation for AFUP in Paris

  Today, I gave a presentation on Traits for PHP in Paris. It was a quite interesting audience, ca. 35 professional PHP developers and all interested in Traits.

• Dec 7, 2010: The Price of the Free Lunch: Programming in the Multicore Era

  Last Friday was the annual Lab event of our Software Languages Lab. Like last year, many people related to the lab in one or the other way came to get an overview of what the current topics of our research are.

• Nov 4, 2010: RoarVM: The Manycore SqueakVM

  We are happy to announce, now officially, RoarVM: the first single-image manycore virtual machine for Smalltalk.

• Nov 2, 2010: RVM Open Sourced, Soon to be known as RoarVM

  Just a brief heads up before the actual announcement of RoarVM.

• Nov 2, 2010: SPLASH'10 Main Conference

  Tuesday – Evolution, Onward!, FPGAs, and the Hera-JVM

• Oct 30, 2010: Workshops at SPLASH 2010

  As usual I will write about a few of my personal highlights of SPLASH and the co-located workshops. That is mostly from my spotty notes, and from memory, so I don’t guarantee 100% accuracy, especially with respect to what other people might have said.

• Sep 22, 2010: Highlights of HPCC 2010

  The 12th IEEE Internal Conference on High Performance Computing and Communications was not the first conference I attended. However, it was the first one where I actually presented a paper in the main research track.

• Aug 4, 2010: Poster at SPLASH’10

  On a related note to the last post, my poster got also accepted for SPLASH’10.

• Jul 30, 2010: Doctoral Symposium at SPLASH 2010

  In October, I will give a brief presentation on the state of affairs with my PhD research at the SPLASH 2010 Doctoral Symposium. The basic idea has not changed since my last presentation at the TiC’10 summer school. I haven’t been able to do a lot of real work for it, but the ideas are a bit clearer now. The following two-page proposal will be published as part of the conference proceedings.

• Jul 6, 2010: Insertion Tree Phasers: Efficient and Scalable Barrier Synchronization for Fine-grained Parallelism

  The last half year was an interesting departure from my actual PhD research. First, I though the idea of barriers and phasers might be interesting to incorporate into a virtual machine as part of my thesis, but as it turned out, they are much to high-level and are better off implemented in a library. The gain for direct support in a VM is just not proportional to the effort and restrictions which come with that step.

• Jun 21, 2010: Trends in Concurrency 2010, part 3

  This is the last post about the TiC’10 summer school and covers the two remaining lectures. Mark Moir talked about concurrent data structures and transactional memory, and last but not least, Madan Musuvathi presented the work they did at Microsoft Research to improve the testing of concurrent applications.

• Jun 14, 2010: Trends in Concurrency 2010, part 2

  This post is a follow up on my first report on the TiC’10 summer school. It covers mainly the talks about X10 and formal aspects of concurrency.

• Jun 7, 2010: Trends in Concurrency 2010, part 1

  I already posted the presentation I gave at the summer school earlier. In the following posts, I will report a bit about the lectures of the summer school, similar to my posts about the TPLI summer school of last year.

• May 25, 2010: Locality and Encapsulation: My Student’s Presentation at the TiC Summer School

  On the first day here at the summer school, the organizers gave us the opportunity to present our research ideas to the lecturers and other participants.

• Feb 21, 2010: Towards an Actor-based Concurrent Machine Model

  Already quite a while ago, I was involved in writing a workshop paper about an actor model for virtual machines. Actually, the main idea was to find a concurrency model for a VM which supports multi-dimensional separation of concerns. However, AOP is not that interesting for me at the moment, so I am focussing on the concurrency, especially the actor-based VM model.

• Feb 14, 2010: Intermediate Language Design of High-level Language Virtual Machines: Towards Comprehensive Concurrency Support

  My second workshop paper got published at the ACM Digital Library. This is actually only an abstract, but nonetheless, it might be interesting for people looking into the design of virtual machines and especially bytecodes/intermediate languages.

• Feb 7, 2010: Virtual Machine Support for Many-Core Architectures: Decoupling Abstract from Concrete Concurrency Models

  Finally, my first workshop paper got published, which was a little odyssey with some misunderstandings, but anyway, now it is out. It is just a position paper, thus, do not expect to many insights. However, what it describes is my big plan, and hopefully the story of my PhD. Am working on it…
