We’ve no experience in real-time software (just the student level). So,as we need to start, we choose a free software :hurd. It will be nice if you’ll be agree to answer our questions.
Here are our interrogations : - Which platforms are allowed with Hurd ? - Could you give us some cross referencer name for development ?do any debugging tools existing ? - Which kind of communication between task are possible ? (mail box ?, shared memory ?, sockets ?) and how do they work ? - How do hurd manage the task memory allocation ?(pagination ?, dynamic allocation ?) - How many tasks can run in the same time ? - What is the time switch between tasks ? - How the task overflow is manage by hurd ? - How context memory is manage ? - About the scheduler : Could you explain us how the scheduler is working ?(time quantum, - dynamic priority). - In comparaison with VXWorks and PSOS+, what does hurd offer more ? - What are the mains problems with hurd ?(deadlocks). - Today, which industrials sectors use Hurd (for which applications) ? - Could you give us a basic example of a Hurd program ? - What is your feeling about Hurd ? We’ve already surf on the web and read GNU sites, but its contains very generals informations. Thanks a lot for your help, cordially, Franck, Dominique, Ludovic, Christophe. (french guys)
