Ifort Quick tips

September 7, 2011 Leave a comment

Not the most convenient representation of a 12x12 matrice, isn'it ?

Ifort is a pretty nice fortran compiler, nevertheless one thing that I find a little bit annoying is its default record length format, when you are testing /debugging a program, it’s always convenient to add a write(*,*) here and there, unfortunately passed the 80th  column the line will be cut and printed on the following line. Fortunately by just adding these oneliner in the shell before running the program

export FORT_FMT_RECL=200

Will do the trick.

This trick is mainly useful while debugging, when you are writing a program, you should prefer to define your data format as precisely as possible, since you never know how your program will be run or compile.
