Hi , I applied patch e17-incr.tar.bz2
available at http://sf.gds.tuwien.ac.at/c/ck/ckrm/
to Suse 2.6.10 kernel. Patch applied
successfully.Then i built the kernel
I inserted modules rcfs, rbce ,
ckrm_numtasks , ckrm_listenaq.
I mounted rcfs filesystem on /rcfs.
subdirectories in this directories
shown were ce , taskclass , socketclass.
I created directory c1 in /rcfs/taskclass/
when i did echo "res=cpu,guarantee=30">
/rcfs/taskclass/c1/shares
output of cat /rcfs/taskclass/c1/shares
does not change. It remains as
res=numtasks,guarantee=-2,limit=-2,
total_guarantee=100,max_limit=100
What i want to do it group some tasks so that
they are allocated some fixed percentage of
cpu time
Please let me know if i am missing some
thing.
To get control over cpu time, you need to apply the cpu controller
patch on top of the CKRM base package. The cpu controller patch for e17
is available at
http://sourceforge.net/project/showfiles.php?group_id=85838
Follow the instructions in Documentation/ckrm/cpusched of the resulting
source tree and it should work for you.
Please note there are a couple of bugs discovered by Peter Williams that
will get fixed in the next update.
