I am confused about CPU THROTTLING.
How can I switch off CPU throttling on SuSE Linux 10.2 ?
I found a command "cpufreq-set" but I don't know how to proceed.
ATLAS uses gfortran by default but I have used g77 to build BLAS/LAPACK.
Can I replace gfortran in Make.inc by g77 ?
I have used
/usr/local/src/ATLAS/configure -Fa alg -fPIC -Si cputhrchk 0
to configure ATLAS (3.7.28)
