It's also probable the newer Fortran compilers would do a better job optimizing the code.

You are also talking about a language that was designed to do very, very heavy computational work and the language was optimized to do that. I can promise you that you can rewrite it however when IBM Mainframes are running a bunch of 5.4 GHz processors it will beat any other "MODERN" language 1500 to 1 And Modern Fortran http://www-03.ibm.com/software/products/en/fortcompfami -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of IronSphere by SecuriTeam Software Sent: Thursday, May 4, 2017 9:28 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Nasa runs competition to help make old Fortran code faster Old compilers that uses many branchs and short words?
