Hello,

I'd like to build the fastest version of Octave I can (depending upon
your definition of "fastest"). Does this mean Intel compilers and MKL?
Any pointers to compiler options?

Thanks!

Jeff

Jeff,

I get fast(no metrics on that other than I am impatient) builds on Scientific Linux (RHEL 7.2) using the following env vars:


export CFLAGS="-march=native -mtune=native -O2 -pipe -Wall"
export CXXFLAGS="-march=native -mtune=native -O2 -pipe -Wall"

GCC version 4.8.5
