I wrote a chapter about Open MPI in "The Architecture of Open Source Applications, volume 2", which was just made available in dead tree form today:
http://blogs.cisco.com/performance/the-architecture-of-open-source-applicat ions-volume-ii/ All royalties from this book go to Amnesty International (I don't get anything). There's lots to learn from this book (and volume 1, too!). The designs of successful, open source software packages that you'll recognize are in these books, including (in no particular order): Open MPI, Bash, GDB, Puppet, Eclipse, Mailman, the Hadoop distributed filesystem, LLVM, Git, Sendmail, ...and many others. I'm told that PDFs will be available soon. Additionally, in good open source form, all the content from this book will be freely available at aosabook.org in a week or so (all the content from volume 1 is already there). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
