[Vm-dev] setting priority limits on non-redhat linuxen

[gettimothy]

Hi All,



For those folks getting the pthread_setschedparam the example Eliot gives at http://www.mirandabanda.org/files/Cog/VM/VM.r3006/README.3006 does not apply to Slackware linux and I suspect other distros too.


I did some digging this morning and figured out how to set this up on my system.


This site https://www.hackthissite.org/articles/read/932 gives an overview, but it is a bit outdated.


On Slackware 14.1 the output of 'man limits'  shows a few more entries





  · A: max address space (KB)

 · C: max core file size (KB)

 · D: max data size (KB)

 · F: maximum filesize (KB)

 · K: file creation mask, set by umask(2).

 · I: max nice value (0..39 which translates to 20..-19)

 · L: max number of logins for this user

 · M: max locked-in-memory address space (KB)

 · N: max number of open files

 · O: max real time priority

 · P: process priority, set by setpriority(2).

 · R: max resident set size (KB)

 · S: max stack size (KB)

 · T: max CPU time (MIN)

 · U: max number of processes









I created the /etc/limits  file and added an entry



 

tty O100

logout out and back in and I was able to run the squeak.cog.v3 build just fine. 

Prior to that limit fix, I was getting the dreaded  pthread_setschedparam  error and could only run the vm as root.


Hope that helps.
