Hi,
I have a modified makefile originally given to me by the PETSc team. It worked well but now I want to change some of the options of the compiler, like using -O3 or -ipo etc instead of -O.
I tried to add -O3 in and the compiling command becomes:
/opt/openmpi-1.4.1/bin/mpif90 -O3 -c -g -r8 -save -w90 -w -w95 -O -I/home/wtay/Lib/petsc-3.1-p5/include ....
So now there's -O3 and -O. How can I change it to only -O3 or -ipo?
I have attached the makefile too.
Thank you very much
Yours sincerely,
