Dr. Dobbs' Journal On Hurd

Posted by ryuzaki0 on from the getting-some-attention-at-least dept.

wiredog pointed out an article that's currently running in Dr. Dobbs that talks about Hurd [?] , what it is, and what it is meant to do, as well as what's cool about it. The article starts off slow, but then gets into some good info.

    There are two major differences between OS X and the Hurd.

    The first difference is that OS X is a single server and the Hurd is a multi-server. That is, on OS X all the Mach stuff communicates with is one large Free-BSD kernel with its hardware dependent stuff ripped out. The Hurd on the other hand has each system call handled by a separate thread of execution.

    The second difference is that Apple moved the BSD kernel into the same kernel space as the Mach microkernel. This means that they don't have the context switching overhead that traditional Mach based systems have.
