So far: Overflows from assigning the values of real calcs to integers without rounding, truncation or conversion (documented in the Readme).
Possible bug, depends on the compiler used: Assign reals to integers without type conversion. At least when I did fortran (f77 on S-100 machiens), that was a random number generator. Overall, the code is downright awful. What I don't understand, given that this is publicly funded research supposedly in the public interest, why there isn't just a "open source" approach. IE, have a sourceforge project for the code, and make the data available to everyone. I'm sure some pretty sharp minds will code up a significantly better set of code to run the models that can run on boinc a lot faster than a few researchers who spend more than half their time on the talk circuit and chasing grants. I wouldn't use the CRU code to set pricing for a lemonade stand, never mind be the foundation for changing the entire world economy. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dan Kaminsky Sent: Tuesday, December 08, 2009 3:56 PM To: Gadi Evron Cc: funsec Subject: Re: [funsec] climate gate and programming bugs Any actual bugs yet?
