Question #76595 on lapack in ubuntu changed:

    Status: Open => Answered

Tom proposed the following answer:
Hmmm, i'm not sure what is going on here but i installed "conky" and
reconfigured the script to show me % usage of each core in a time-graph
and see that most of my normal usage is split between both cores -
usually about 20% of one core and maybe about 50-60% of the other.  When
i start pushing my machine a bit more it sometimes builds up to 40-50%
on one core with still about 50-60% in the other - i haven't yet been
able to find an excuse to push my machine beyond that because by the
time i have about 50% on both cores i already have all my heaviest apps
open and running.  I'm thinking about installing a Windows game at some
point but haven't got around to it yet.

So i really suggest trying to use install and adapt "conky" to
dynamically monitor what  % usage you get from each core in what it
calls a "bar chart" <sighs> <shakes head> - still although the name is
probably american it does seem to do very much the right job.

In the meantime thanks for giving us a link to the website of the
program you are talking about.  I'm just about to start reading that now
in case i spot something obvious but i have no experience with fortran
so doubt i'll be much use understanding that.

Anyway, hopefully between us all we'll spot something and work out what mis-communication is going on & where.
Thanks, good luck and regards from
Tom :)
