Friday, den 9. October 2009

There was a brief pause in my blogging as I have been assimilating some of the new developments in the multicore realm.  Some of the items are close to home for me at my respective company with the acquisition of Wind River, Cilk Arts, and RapidMind.  I’m not at liberty to comment on strategy, future [...]

Big endian + Little endian byte order = biendian

Wednesday, den 29. July 2009

Today, I wanted to share a bit on a project I’ve worked on for a couple of years now as we’ve had some recent success. 
 One fairly subtle issue in migrating code from one architecture to another is byte order.  For a more detailed summary of the issue, I encourage you to read Matassa’s paper [...]

MPP: On Documenting Best Known Methods for Multicore

Thursday, den 12. March 2009

Embedded multicore interview followup

Friday, den 20. February 2009

Had a nice interview and mention in an article by John Blyler.
With regard to the issue identified in the story and video (coordination of process, thread, and vector level parallelism), I think there is a positive and a negative aspect for embedded developers.  The negative aspect for embedded developers is that much of the work for [...]

Early February finds me working on talks and papers for Embedded Systems Conference Silicon Valley.  I really do enjoy attending the conference every year and they really do treat their speakers well.  I’ve had the opportunity to hear keynotes from Al Gore and Dean Kamen (Segway inventor).  This year’s keynote is from Ken Mattingly of [...]

My content was similar to a talk I delivered in Japan earlier this year. [...]

Thoughts on the endstate of multicore software development

Friday, den 19. September 2008

I recently read two interesting articles on multi-core programming from different angles. One is from a noted compiler writer who is a creator of development tools that enable multicore/multiprocessor programming:
http://www.hpcwire.com/features/Compilers_and_More_Parallel_Programming_Made_Easy.html
The second article is an interview with a noted game programmer, who would be a consumer of such development tools:

Both of these are good reads. [...]
