Date: 5 Dec 1995 03:51:09 GMT Hi. First time kernel-hacker here, and I need some help. Seeing that Linux is not POSIX.4 compliant, how can I do an asynchronous read? Is this something I need to do on a per-fs basis, or is there some mechanism I can build on top of the existing sys_read? Has anyone implemented an in-kernel asynchronous read before, and if so how? Thanks in advance! Please cc any reply via mail. Bret Mogilefsky PS: In case you're interested, here's why I need it: I am doing an experiment for my grad-level OS course here at Cal Berkeley. I'm attempting to implement a mechanism from Windows NT called IO Completion Ports that is supposed to cut context switches in a multithreaded server by using asynchronous reads along with a rendezvous port to allow threads to run their whole quanta without a context switch... Supposedly this is a big performance boost in NT, but my partners and I want to know if that's because select() sucks in NT or if it's a true claim. The hope is that we can bench both select() and IOCompletionPorts under Linux and see if the performance increase is worth it. If so, then we'll refine what we have and submit it for inclusion in the kernel. And uh, guess how much time we have to do this in? -- "Why, that's the second biggest monkey head I've ever seen!" --Guybrush "LeChuck's dead.

If you think about, Ghostscript does this. ps -> raster image -> print encoder All we need is something that might work like this. pbm -> raster image -> print encoder I propose that we examine how ghostscript does the encoding for various printers and expand on the BubbleTools project.
