Systematically Exposing OS Kernel Races – An Interview with Ben Blum

By Jakob Engblom Full-system simulators like Simics provide unparalleled insight into what is going on in a target system. Indeed, better insight is one of the main features of simulation that we get regardless of what we simulate and how. In addition, if we want to, we can also exert control over the target system to make it take different…

Analyzing Manycore Scaling with Simics

By Jakob Engblom In my previous blog post on multicore scaling investigations with Simics, I tested a simple parallel program on a variety of machines. The scaling obtained was not particularly impressive, especially not on a 60-core target machine. In this post, we will use the Simics timeline view to look a bit closer at what is going on inside the…

Simplifying M2M

By Brian Vezza Today, Wind River is taking a significant step forward in simplifying machine-to-machine (M2M) development for our customers.  We announced the Wind River Intelligent Device Platform which builds upon Wind River’s operating system and tools leadership with M2M middleware to make it easier to design, build, and operate M2M or smart connected devices.
