All eyes on Larrabee

By Doug Schaefer There's been a bit of talk on the web-o-sphere about a report out of the German tech magazine Hiese.de that claimed that the Larrabee multi-core processor that Intel was working on will contain 32 original (well, second generation, but still 20 years old) Pentium cores. In the end, it appears to be just speculation and Intel was…

Are you ready for 100 cores?

By Doug Schaefer Massively parallel computing is something I've been interested in for a while and have blogged about a few times in the past. This blog entry by an Intel Researcher made me think about it again. He continues to proclaim that the future isn't that far away and we had better start designing our software so that it…

Processing Paradigm: it’s all about capacity

By Mike Deliman When I was a kid anything that was a computer, or had one in it, was pretty obvious. Computers weren't "just everywhere".  Now we've got multiple CPU chips on a board, multiple CPU cores on a chip, different kinds of cores on a single chip, multiple computer boards in a single chassis, ... it goes on.   …

“Making Multicore Work” Seminars

By Paul Tingey February has been a particularly busy month. So busy, in fact, that I was not able to make time to be at the Mobile World Congress in Barcelona. Instead I have spent most of the month completing a tour of seven European cities presenting at a joint Wind River/Freescale/Virtutech seminar series. The theme of the seminar was…

RDC in China

By Tomas Evensen I just came back from a couple of weeks in China. Fascinating country. Besides the usual customer visits, we also held three Regional Development Conferences (RDCs) in Shenzhen, Shanghai and Beijing. The RDCs were a huge success with on average more than 400 attendees per day. And they were all very interested in hearing about Wind River's…

Is safety-critical ready for multi-core?

By Paul Parkinson You may feel that you're experiencing déjà vu reading this blog, but the title 'Is safety-critical ready for multi-core?' is different to an earlier blog, which was 'Is multi-core ready for safety-critical?'. In the earlier blog, I discussed some recent developments in multi-core processors in the context of their suitability for use in safety-critical systems. In this…

Telecoms equipment can be cool (honestly)

By Paul Tingey Many years ago, at a previous company, I spent my days writing assembler code for the 68302 processor and watched enviously as other (more fortunate) engineers wrote "modern" C++ applications for Pentium-II desktop PCs. In the canteen at lunchtime, no-one wanted to listen to my witty anecdotes about humorous 68K register names. At a technology level, embedded…

Is multi-core ready for safety-critical?

By Paul Parkinson I recently attended the Military & Aerospace Electronics conference in the UK, at which a number of technical presentations were given on new technologies relevant to this sector, including an excellent one by Gordon Hunt of RTI on the Data Distribution Standard (which probably deserves a blog entry in its own right). However, the presentation which I…

Intel and Multicore Tools

by Tomas Evensen Intel is releasing tools to help programmers to deal with multicore. See the news.com story: Intel: Optimize applications for multicore. In the the article, James Reinders states that "It's not intrinsically harder to write threads, but developers need to get used to thinking that way and we need help from the tools." While I agree that developers…
