CPU Utilization too Low With Cycle Hungry App
I am running kernel v 2.4.21-99 with suse 9.0 distribution.
Machine: P4 3 GHz with HT and 800 MHz FSB. 1GB RAM.
I find (from top) that my CPU is never utilized more than ~55% even
when I am running my most cycle hungry apps (e.g. xcorr in matlab ).
Approx 40 % of the CPU is idle.
Running the same code on a different Linux box (not sure which
kernel) shows 98% utilization so I don't believe that the
app is the issue here.
I would like to increase the utilization to make my app faster.
Is it possible that there is a hard limit set somewhere in the config
to prevent me from using the CPU further? Or, is there something
else I can do?
