Purpose. ! -------- ! Control routine for the direct spectral transform !** Interface. ! ---------- ! CALL DIR_TRANS_CTL(...) ! Explicit arguments : ! -------------------- ! KF_UV_G - global number of spectral u-v fields ! KF_SCALARS_G - global number of scalar spectral fields ! KF_GP - total number of output gridpoint fields ! KF_FS - total number of fields in fourier space ! KF_UV - local number of spectral u-v fields ! KF_SCALARS - local number of scalar spectral fields ! PSPVOR(:,:) - spectral vorticity ! PSPDIV(:,:) - spectral divergence ! PSPSCALAR(:,:) - spectral scalarvalued fields ! KVSETUV(:) - indicating which 'b-set' in spectral space owns a ! vor/div field. Equivalant to NBSETLEV in the IFS. ! The length of KVSETUV should be the GLOBAL number ! of u/v fields which is the dimension of u and v releated ! fields in grid-point space. ! KVESETSC(:) - indicating which 'b-set' in spectral space owns a ! scalar field. As for KVSETUV this argument is required ! if the total number of processors is greater than ! the number of processors used for distribution in ! spectral wave space. ! PGP(:,:,:) - gridpoint fields ! The ordering of the output fields is as follows (all ! parts are optional depending on the input switches): ! ! u : KF_UV_G fields ! v : KF_UV_G fields ! scalar fields : KF_SCALARS_G fields ! Method. ! ------- ! Externals. SHUFFLE - reshuffle fields for load balancing ! ---------- FIELD_SPLIT - split fields in NPROMATR packets ! LTDIR_CTL - control of Legendre transform ! FTDIR_CTL - control of Fourier transform ! Author. ! ------- ! Mats Hamrud *ECMWF* ! Modifications. ! -------------- !
