On Wednesday this week, I will take part of a panel discussion about virtual platforms and using them for software development, at the IP08 conference in Grenoble in France. We have a good crew, including Markus Willems from Synopsys, Peter Flake from ELDA, and Loic le Toumelin from TI (who I have not met before).
I will give a presentation on how Simics was threaded and how we created a parallel virtual platform system at the SiCS Multicore Days 2008, which takes place in Kista, Sweden, on September 11 and 12. The schedule is now up (so I edited the post and added updated to the title), at http://www.sics.se/node/3182, and my talk is on Friday, Sept 12, at 13.00 in “track 2”. Speaker bios and abstracts are also online.
Even apart from my own humble participation, I think the event itself will be well worth attending. Last year was really good and serious fun! See my writeups from last year: part 1 and part 2 (and a short note on the Rock processor and transactional memory).
The slides from the Power Architecture Conference in München and Paris are now online (and have been for a few weeks) at the Power.org site for the event. Some interesting things there about Power Architecture in particular but also virtual platforms were an almost main theme of the show.
On Tuesday next week, I will be presenting at the Power Architecture Conference (PAC) in München, Germany. The topics will be multicore debug using virtual hardware, and the new Simics Accelerator technology. Especially Simics Accelerator is pretty interesting technology.
It is a simple idea, using multiple host cores to run a virtual platform, with fairly amazing results. Now, using a single computer we can run fairly incredible simulations that were the realm of pure fantasy just a few years ago. We also got a nice new little box to demonstrate it with, an eight-core Dell with 16 GB of RAM. With 64-bit Linux, this thing makes my Core 2 Duo laptop with 32-bit Vista look like yesteryear’s snail… And creates that giggling feeling that a really impressive new toy brings up in even the most grown up boys. Booting a 16-machine network of PowerPC boards was so fast it was not demoworthy. I think we have to up the ante to some 100 target machines to make it interesting, and I have no doubt that a combination of multithreading and idle-loop optimization will make that thing be usefully interactive from the target command lines. There are many other wild things we could try on that demo box, once it gets back from the Power Architecture Conferences tour.
Now the ESC SV 2008 is over. I really enjoyed going to the show this year, and presenting on simulation for embedded systems. The topic has to be heating up, I had some fifty people listen to the talk, which is really very good. Hope that they learnt how to build good transaction-level hardware models, and have some idea on how to apply this to their own projects. Hopefully, I can come back next year for the ESC 2009 (update: this did not happen) and do it again (even though the recent travel trouble makes it a less attractive idea to fly back here right now…).
Just like in 2006, I went to the Øredev conference in Malmö and presented a workshop using Virtutech Simics. This year, I worked with Jonas Svennebring from Freescale and we created a workshop around parallelizing network processing software for running on a multicore Freescale processor. The workshop went reasonably well, and the participants definitely learned something about what we trying to get across, even though we did not have much time to actualy complete the programming assignments.
Back in 1996, DVP celebrated its 15th anniversary. When looking through my digital and paper archive, I found this gem: The official badge and logo for the 1996 anniversary! We also produced some mouse pads with this logo on them, one of which I still use for my daily job. Pretty good quality I must say.
The picture shown here was saved as GIF for use on the web. But scarily enough, apart from a few more GIF files, I could not open or even understand the file type of most of the files from that time, only ten years ago. Our digital archives are not very robust — more on that below.
The SICS Multicore Day August 31 was a really great event! We had some fantastic speakers presenting the latest industry research view on multicores and how to program them. Marc Tremblay did the first presentation in Europe of Sun’s upcoming Rock processor. Tim Mattson from Intel tried hard to provoke the crowd, and Vijay Saraswat of IBM presented their X10 language. Erik Hagersten from Uppsala University provided a short scene-setting talk about how multicore is becoming the norm.
My dear old education program, DVL, later DVP, (which made us call it DV*) is celebrating its 25th anniversary with a large dinner at Norrlands Nation on October 6, 2007. The official site is www.dvp.nu/25. I really hope that I can make it, it would be great seeing all of the other alumni frÃ¥n datavetenskapliga linjen/programmet and see where they have ended up and what they are doing now.
They also emailed out a call for pictures from the history of DV*. I’ll look through my old collections of memorabilia and see what I can find. What a chance for a trip down memory lane. It’s been ten years since I graduated. Time flies.
RTiS 2007 just took place in Västerås, Sweden. It is a biannual event where Swedish real-time research (and that really means embedded in general these days) presents new results and summarizes results from the past two years. For someone who has worked in the field for ten years, it really feels like a gathering of friends and old acquaintances. And always some fresh new faces. Due to a scheduling conflict, I was only able to make it to day one of two.
I presented a short summary of a paper I and a colleague at Virtutech wrote last year together with Ericsson and TietoEnator, on the Simics-based simulator for the Ericsson CPP system (see the publications page for 2006 and soon for 2007). I also presented the Simics tool and demoed it in the demo session. Overall, nice to be talking to the mixed academic-industrial audience.
