Hi Maeda,

Another CPU hog process, such as an infinite loop must be run on the
other
class. Otherwise kernbench can consume whole CPU time regardless of its
share.
Please not that it is a guarantee, not limit. Even though other class
try to
consume over 80% of CPU, 20% is guaranteed for C1. It is the function.

Thanks,
MAEDA Naoaki
Thanks. So is it enough to run a while(1) process in the default class
to see a difference ?
Also do you mean I am correct in my methods of configuring shares and
using the kernbench tool ?
Now I feel that I should have moved the pid of kernbench to C1 instead
of looking for the pids of "make -j 4" in "ps -ef" and moving them to
C1..am I right ?
Also I am not able to set the limits. When I echo the limit and the
max_limit values to the shares files, it doesn't get changed.. I tried
to set the max_limit of the default class to 100 and limit of C1 to 30.
Regards,
Rajaram.
