schedutils 0.0.5
I would like to publicly announce "schedutils" - a suite of scheduler-related tools for Linux. They are simple GNU-style utilities in similar fashion as the other Linux utility packages - except they manipulate the scheduler. They are released under the GNU GPL v2. Version 0.0.5 can be had at: source tarball: http://tech9.net/rml/schedutils-0.0.5.tar.gz i386 RPM: http://tech9.net/rml/schedutils-0.0.5-1.i386.rpm source RPM: http://tech9.net/rml/schedutils-0.0.5-1.src.rpm Currently there is no standard utilities for manipulating scheduler parameters. Thus this has two goals: first, to provide utilities for such manipulation. Second, and most importantly, to provide a _standard_ suite of utilities for such manipulation. Something that can be depended on to exist in distributions, etc. etc. Right now the package consists of four utilities and their associated documentation: rt(1) - get or set the real-time scheduling class and priority of an existing pid, or launch a new task with a given class and priority. taskset(1) - get or set the CPU affinity of a given pid, or launch a new task with a given CPU affinity. This requires the 2.5 kernel or a patched 2.4 kernel (see my website for patches). irqset(1) - get or set the CPU affinity of a given interrupt. This is implemented as a bash script which parses the `/proc' output. lsrt(1) - list real-time processes on the system, their priorities, and their scheduling class. Right now RT information is not exported out of `/proc' so ps(1) does not display this information. A better solution may be to export this information from `/proc' but for now this exists (and is most likely much faster). There is some basic information and complete man pages in the package. The RPM was built on RedHat 7.3 but should work on any 7.x release and perhaps even any glibc 2.2.x RPM-based distribution. Source users can do: ./configure [options] make make install I am open to any suggestions, bugs, patches, complaints, etc. The idea here is to provide standard utilities for scheduler-related stuff.
