    v199 v200  
    676676By default, system-specific, optimized routines from external vendor libraries are used. However, these are available only on certain computers and there are more or less severe restrictions concerning the number of gridpoints to be used with them.\\\\
    677677There are two other PALM internal methods available on every machine (their respective source code is part of the PALM source code):\\\\
    678 1.:  The '''Temperton'''-method from Clive Temperton (ECWMF) which is computationally very fast and switched on with '''fft_method''' = '' 'temperton-algorithm'.'' The number of horizontal gridpoints ([#nx nx]+1, [#ny ny]+1) to be used with this method must be composed of prime factors 2, 3 and 5.\\\\
     6781.:  The '''Temperton'''-method from Clive Temperton (ECMWF) which is computationally very fast and switched on with '''fft_method''' = '' 'temperton-algorithm'.'' The number of horizontal gridpoints ([#nx nx]+1, [#ny ny]+1) to be used with this method must be composed of prime factors 2, 3 and 5.\\\\
    6796792.:  The '''Singleton'''-method which is very slow but has no restrictions concerning the number of gridpoints to be used with, switched on with '''fft_method''' = '' 'singleton-algorithm'.''
