problems on linking cluster fft function

Raemon — Tue, 09 Feb 2010 19:47:28 GMT

Hi,

I follow the link line advisor and use this link line:

[bash]MKLPATH="/opt/intel/Compiler/11.1/056/mkl/lib/em64t"
mpif90 test4.f90 -L$MKLPATH $MKLPATH/libmkl_solver_lp64.a -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_cdft_core.a $MKLPATH/libmkl_intel_thread.a $MKLPATH/libmkl_core.a $MKLPATH/libmkl_blacs_intelmpi_lp64.a -Wl,--end-group -openmp -lpthread[/bash]

My problems is that: it seems the compiler cannot recognize cluster fft functions.

Here are some of the error message:

[fortran]test4.f90(78): error #6284: There is no matching specific function for this generic function reference.   [DFTICREATEDESCRIPTORDM]
STATUS = DftiCreateDescriptorDM(MPI_COMM_WORLD,DESC,DFTI_DOUBLE,DFTI_COMPLEX,2,length)[/fortran]

I've added these lines in my program:

Include "mkl_cdft.f90"

USE MKL_CDFT

But it doesn't help. (Ubuntu9.04 64bit+MPICH2+ifort 11.1)

Any ideas?

Hi raemon,

Compiling include/mkl_cdft.f90 and putting mkl_cdft.o onto the link line may help.

mpif90 $MKLPATH/include/mkl_cdft.f90 -c -o mkl_cdft.o

mpif90test4.f90mkl_cdft.o -L$MKLPATH$MKLPATH/libmkl_solver_lp64.a
-Wl,--start-group$MKLPATH/libmkl_intel_lp64.a$MKLPATH/libmkl_cdft_core.a
$MKLPATH/libmkl_intel_thread.a$MKLPATH/libmkl_core.a$MKLPATH/libmkl_blacs_intelmpi_lp64.a
-Wl,--end-group-openmp-lpthread-lm

See examples/cdftf/makefile for an idea.

Evgueni.

Hi, Evgueni :

I've looked examples/cdftf/makefile and it really helps. Those examples are useful as well. Now I can link my code without any problem.

Thanks a lot!

Best Regards,

Raemon
