Time to Do Something New

The time has come to do something new. I am leaving Intel (and the Intel Simics team) at the end of September (2024). After more than twenty years with the team and the product this is a big step into the unknown. But when Intel offered a “retirement” package as part of its current round of cost reduction measures, I felt that it was a golden opportunity to find something new to do.

The Event at the End of Universe

This is a short story from the world of virtual platforms. It is about how hard – or easy – it is to model a simple and well-defined hardware behavior that turns out to mercilessly expose the limitations of simulation kernels.

Intel Blog: Parallelizing a Virtual Platform Model

There are many ways to use threading and parallelization to improve the performance of virtual platforms. It is not always easy to successfully use parallelization – it very much depends on the nature of the workloads and model setup – but when it works it can really help. I recently published a long blog post at Intel, detailing an idealized example of threading for a device model that is shipping in the Simics training package.
