Value of C_LONG_DOUBLE 12 98 (11/22/2011 11:08:57 PM) comp.lang.fortran gfortran and ifort give different values for C_LONG_DOUBLE for the ISO_C_BINDING on the same machine: $ cat test.f90 PROGRAM MAIN USE ISO_C_BINDING PRINT *,C_LONG_DOUBLE END $ /opt/intel/bin/ifort test... Rick

g95 and FFTW 18 166 (4/22/2010 8:33:59 PM) comp.lang.fortran I'm using both in-place and out-of-place real-data FFT in the same program, with FFTW3. Something along those lines: DOUBLE PRECISION :: bR(2*(L/2+1),L) DOUBLE PRECISION :: aR(2*(L/2+1),L) DOUBLE COMPL... Rick

Fortran preprocessor on free-form source code 3 134 (7/31/2009 12:18:42 PM) comp.lang.fortran Is there any way to let the Fortran pre-compiler (at least ifort) accept spaces before #IFDEF? Example: PROGRAM MAIN IMPLICIT NONE #IFDEF MULTI PRINT *,'Multi' #ELSE PRINT *,'NOT MULTI' ... Rick

Template metaprogramming 2 73 (3/10/2009 10:55:17 AM) comp.lang.fortran Are templates for metaprogramming available with Fortran ? http://en.wikipedia.org/wiki/Template_metaprogramming ... Rick

More a general programing question than anything specific to Fortran... 15 28 (1/30/2009 12:23:40 PM) comp.lang.fortran I have a code like: INTEGER i,L,n,mode L=1000000 mode=... ! value may be different at each run DO i=1,L IF (mode==1) THEN n=i ELSE n=i+1 ENDIF ! do something with n ENDDO For speeding up thing...

FFTW3 with Fortran? 1 39 (10/1/2008 1:54:55 PM) comp.lang.fortran What would be the best (easiest) way to use FFTW3.2alpha3 (or FFTW 3.1) with Fortran and MPI? The Fortran wrappers for FFTW-MPI are not available since FFTW 2.1. According to benchmarks, FFTW #3 is roughly two ... Rick

MPI beginner 11 119 (9/29/2008 8:57:45 AM) comp.lang.fortran This is probably a silly question, but: is there a standard way to compile the same code with ifort using MPI or not using it? For instance, I could provide line of codes that would apply in each of the two cas... Rick

ALLOCATABLE arrays in TYPES with gfortran 11 34 (2/18/2008 8:32:53 PM) comp.lang.fortran Is it possible to use allocatable arrays in types with gfortran, like: PROGRAM MAIN IMPLICIT NONE TYPE myType DOUBLE PRECISION, ALLOCATABLE, DIMENSION(:) :: E END TYPE TYPE(myType) :: a ! ALLOCATE... Rick
