Realtime OS Jaluna

Posted by michael on from the all-together-now dept.

rkgmd writes "Jaluna-1, a software component suite based on the respected chorus realtime os is now available in opensource (MPL-derived license) form. Jaluna, the company behind this, is a spin-off from sun to promote and develop chorus, and consists of many developers from the original chorus team before it was acquired by Sun. Chorus developed one of the earliest successful microkernel-based rtos's (could even run parallel, distributed unix in realtime on inkos transputers in 1992). Lots of good research papers here, and a link to the original newsgroup announcement."

    How does this compare with QNX?

      That's true, although I'm not a big QNX guy, I did work on developing ChorusOS 4.0 about 3 years ago at Sun's Grenoble facility. I can say that Chorus had a much better memory management model that AE does, and it was very stable on PPC embedded platforms. It also did C++ more natively than other RTOS offerings.

      I know, C++ in the embedded world? C++ in an OS? Well, when done with some forethought and a brain, it's not an altogether bad idea.

      As well, I think it's really big failing was that Sun pretty much never put ANY effort into promoting or pursuing this outside of some half hearted attempts to get it into the auto and cellular infrastructure industries. They pretty much let it die a slow painful death. Couple that with the less than warm relationship between Sun's team and the original Chorus guys, and the requirements that it's few customers had, and you have a recipe for failure. It's good to see it came back. Time to dig out the blades at work and see if I can get it running again. WooHoo, nerd work!

  2. Sounds fascinating... by carl67lp · · Score: 3, Interesting

    But it's really too bad that my university doesn't teach this stuff.

    It's something I realized the other day; we have so many advances in the field of computer science, such as Jaluna, and yet our centers of learning don't touch it. In fact, Java isn't even a core requirement in my plan of work!

    When is it that we'll finally be able to have a good environment for learning all of these spectacular technologies?

    I agree that without a solid theoretical foundation it is difficult to grasp what is actually going on "behind the scenes."

    But my largest point of contention with my university is that all of the courses above the C++ programming level are theory--no hands-on practice anymore, unless you take electives (like Java, or XML, or advanced Web design--and only here do you learn a modicum of Perl). It's to the point now where my resume reflects the fact that I self-taught myself Linux, Windows 2000/XP (and server derivatives), Perl, PHP, HTML, and more.

    Universities are supposed to keep pace--not have the attitude of "let's worry about all that new-fangled stuff later." If it means refreshing their curriculum every two years, then so be it.

    Of course, I wish I knew then what I know now--I wouldn't have chosen this university at all.
