Re: [math-fun] Custom number crunching programs --- expectations?

P.S.: should you ever use C++ and note that stdin/stdout are very slow (they are by default), use ios::sync_with_stdio(false); Of course you must not use C input/output in the same program then.

Don't count on this. In particular, this does not appear to change the performance when using newer, LLVM-based compilers (and yes, the performance is still incredibly bad). If you need high-performance I/O you should probably just use plain old C I/O. -tom -- -- http://cube20.org/ -- http://golly.sf.net/ --
