Installed non smp kernel and tried using taskset but it doesnt seem to be working<br><br>Here is what I did:<br><br>Prompt>taskset -p 03 4368<br>pid 4368's current affinity mask: 1<br>pid 4368's new affinity mask: 1<br>
<br>Prompt>taskset -p 02 4368<br>
pid 4368's current affinity mask: 1<br>
pid 4368's new affinity mask: 1<br><br>You can see that it wont set it to anything but 1. Also, when I issue the following command:<br><br>cat /proc/cpuinfo<br><br>Only 1 processor is showing...what can I do to resolve this (apart from using an smp kernel!)

the load on the machine will be high because you still have the problem that
each process has to wait until he gets processor time.. I'm curious what
your vmstat is saying in this cause.. Can you run a vmstat 5 for my for about 5
minutes and let me know what the procs/b is saying… This line indicates
how many procs are waiting until they are getting cpu time….</span></font></p>

<p style="margin-left: 36pt;"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Yes
verry… I run a dual amd cpu system, and made a while back to start the
wrong kernel… At that moment everything was separated on one cpu per
process. That isn't the problem, what the problem is is that you
can't say wich process is going to wich cpu, and that means in my case
that one cpu was overloaded and one was doing nothing. Because of this there
was a high load on my machine because everything had to wait until it can get
cpu power… So for a short story… Keep using smp…</span></font></p>

<p style="margin-left: 72pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Im running a dual pentium
mandrake 10.1 server with an smp kernel. The server runs 2 cod servers and 1
cod2 server<br>
<br>
Would I notice a big difference in performance if I switched to a non smp
kernel?<br>
<br>
Thanks</span></font></p>
