Lies, damn lies, and benchmarks.
I know as a long-time C programmer, there are small changes I can make to source that will result in big-time performance gains.
Could hinge on how tight their FORTRAN code is vs their C code...
Could also depend on how much love their respective machine code translations have been getting.
- dfgasfjhjhsdojj 10y agoFortran hasn't been all caps for nearly 30 years now... It is very easy for a physical scientist to write Fortran that performs well - the syntax looks very similar to the maths that is being modeled. It is a lot harder for a scientist to write tight C code.
- jstewartmobile 10y agoNot bashing Fortran here, I'm defending it.
- igouy 10y ago> small changes … result in big-time performance gains. Look and you might see measurements of several different C or C++ or … programs doing the same task with different performance. https://benchmarksgame.alioth.debian.org/u64q/performance.php?test=nbody https://benchmarksgame.alioth.debian.org/u64q/performance.ph...
