Speaking at Embedded Conference Scandinavia

2012 August 29 12:58 / Leave a Comment / Jakob

I am going to be talking about how to transport bugs with virtual platform checkpoints, in the Software Tools track at the Embedded Conference Scandinavia, on October 3, 2012, in Stockholm (Sweden). The ECS is a nice event, and there are several tracks to choose from both on October 2 and October 3. In addition to the tracks, Jan Bosch from Chalmers is going to present a keynote that I am sure will be very entertaining (see my notes from a presentation he did in Göteborg last year).

Wind River Blog: Testing Multicore Scaling with a Simics QSP

2012 August 27 21:39 / Leave a Comment / Jakob

A few years ago, I built a demo on Simics that used a hacked Freescale MPC8641D target that was forced to scale from 1 to 8 cores. Some interesting experiements could be made using this target, and it was nicely scalable for its time. However, I always wanted to have something just a bit bigger. Say 20 cores, or 100. Just to see what would happen. Finally, I got it.

The Simics QSP target that we quietly launched earlier this Summer is such a scalable target. As discussed in a blog post describing the architecture, it is designed to scale to 128 cores currently. Using this ability, I repeated my old experiments, but trying very large threads counts and target core counts. The results show clearly that the way that I coded my parallel computation program was pretty bad, and I really would like to try to rewrite it using some more modern threading library. All I need is time and a way to cross-compile Wool…

Anyway, the new blog post is here.

Speaking at SiCS Multicore Day 2012

2012 August 16 11:43 / Leave a Comment / Jakob

I am scheduled to talk at the SiCS multicore day 2012 (like I did back in 2009 and 2008). The event takes palce on September 13, at SiCS in Kista. My topic will be on System-Level Debug – how we can make debuggers that work for big systems.

This year, the multicore day is part of a bigger Software Week event, which also covers cloud and internet of things. See you there!

Buying High Technology

2012 August 8 02:19 / 1 Comment / Jakob

Selling and marketing high technology is what I do for a living. My counterpart is the customer or buyer, and I help design, build, explain, an market these products.  In this role, I am most usually the expert on the domain, helping potential customers understand what we sell and why it will help them.  Both at the high-level value proposition and the details behind it.  Some people focus most of the their energy on the high-level value proposition, but I feel that youoften need a bit detail backing that as well.

I recently had the enlightening experience of being on the buying side instead, experiencing the transition from high-level value proposition to low-level details.  It struck me as being quite similar to what the customers for our virtual platforms would experience when coming in new to the field.

I bought a camera.
