The Embedded World in Nürnberg is still going strong as the best tradeshow for “Embedded” in the world. This year, I spent time doing booth duty and gave a talk in the Conference part of the event. There was an unusual high number of old friends and business acquaintances around, and it was a great experience overall with many fruitful discussions and connections for the future. However, it seems that there is always something that goes slightly awry with my travel to the show…Continue reading “Embedded World 2019”
I had the honor to have a scheduled talk at the Embedded World 2018 show in Nürnberg, right at the start of the show on Tuesday morning. Getting to Nürnberg for the Embedded World without paying a fortune for plane tickets is tricky due to all the other people flying down from Swedish embedded and tech firms at the same time. This year, I was lucky and I had managed to get a very convenient flight at a decent price. Leaving Stockholm in the afternoon around 14.00 on Monday, flying via Frankfurt and then on to Nürnberg, arriving in the early evening just in time for a nice Bavarian dinner. No stress, no late evenings on the U-Bahn into town. A good night’s sleep before getting up and getting to the show with plenty of time to set up for my talk. What could possibly go wrong?
I will be presenting an Exhibitor Forum talk at the Embedded World in Nürnberg next week, about how to get to Agile and small batches for embedded. Using simulation to get around the annoying hard aspect of hardware.
A while ago, I visited my Intel colleagues in Costa Rica and ran a workshop for university teachers and researchers, showing how Simics could be used in academia. I worked with a very smart and talented intern, Jose Fernando Molina, and after a rather long process I have published an interview with him on my Intel blog: https://software.intel.com/en-us/blogs/2017/12/05/windriver-simics-to-inspire-teachers-costarica
In a previous Intel blog post “Question: Does Software Actually Use New Instruction Sets?” I looked at the kinds of instructions used by few different Linux setups, and how each setup was affected by changing the type of the processor it was running on (comparing Nehalem to Skylake). As a follow-up to that post, I have now done the same for Microsoft* Windows* 10. In the blog post, I take a look at how Windows 10 behaves across processor generations, and how its behavior compares to Ubuntu* 16 (they are actually pretty similar in philosophy).
inThere will be a session on checkpointing in SystemC at the upcoming SystemC Evolution Day in München on October 18, 2017. I will be presenting it, together with some colleagues from Intel. Checkpointing is a very interesting topic in its own right, and I have written lots about it in the past – both as a technology and it applications.
I have a two-part series (one, two) on testing posted on my Software Evangelist blog on the Intel Developer Zone. This is a long piece where I get back to the interesting question of how you test things and the fact that testing is not just the same as development. I call the posts Mindset and Toolset
On my Intel Software Evangelist blog, I just published an updated version of an interview I first published back in May, about how to use Intel CoFluent Studio for IoT system architecture. This is a really cool story, about how you can use a calibrated simulation model to architect and analyze software performance before actually writing the code! I
My first blog post as a software evangelist at Intel was published last week. In it, I tell the story of how our development teams used Simics to test the software behavior (UEFI, in particular) when a server is configured with several terabytes of RAM. Without having said server in physical form – just as a simulation. And running that simulation on a small host with just 256 GB of RAM. I.e., the host RAM is just a small fraction of the target. That’s the kind of things that you can do with Simics – the framework has a lot of smarts in it.
It was rather interesting to realize that just the OS page tables for this kind of system occupies gigabytes of RAM… but that just underscores just how gigantic six terabytes of memory really is.
This really happened last week, but I was in the US for the DAC then. I did another blog on Intel Software blog, about a white paper that Wind River put out about how they use Simics internally. The white paper is a really good set of examples of how Simics can be used for software development, test, and debug – regardless of how old or new the hardware is. It also touches my favorite topic of IoT simulation and scaling up – Wind River is actually using Simics for 1000+ node tests of IoT software!

I love bug and debug stories in general. Bugs are a fun and interesting part of software engineering, programming, and systems development. Stories that involve running Simics on Simics to find bugs are a particular category that is fascinating, as it shows how to apply serious software technology to solve problems related to said serious software technology. On the Intel Software and Services blog, I just posted a story about just that: debugging a Linux kernel bug provoked by Simics, by running Simics on a small network of machines inside of Simics. See https://blogs.intel.com/evangelists/2016/05/30/finding-kernel-1-2-3-bug-running-wind-river-simics-simics/ for the full story.
