newbi: using mkl examples - i.e. #include "mkl_dfti_examples.h"

Erich_Zwyssig — Fri, 04 Jun 2010 16:18:39 GMT

Hija all

The examples in e.g. /opt/intel/mkl/10.2.2.025/examples/dftc/ use

#include "mkl_dfti_examples.h"

Where do I find the object (or .c) files to link the examples?

Thanks for your help

Erich

Hi Eric,

Try to find it in directory /examples/dftc/source/

With best regards,

Alexander Kalinkin

Hi Alex

Thanks for your reply. I tried to find mkl_dfti_examples.o or .c, but I see that these routines
are in

- dfti_example_status_print.c
- dfti_example_support.c

Would you be able to tell me what the error below means?

g++ -c -Wall -g -I include -I /usr/include -I /opt/intel/mkl/10.2.2.025/examples/dftc/source -I KLINCLUDE -I PPINCLUDE src/mkl_dfti_example.cpp -o mkl_dfti_example.o

Do you ask about the location of the example sources, the MKL header files or the MKL library?

Anyway, all these are located in a fairly logical and simply organized set of directories. For example, the libraries on our system are in /opt/intel/mkl101/lib/em64t. the header files in /opt/intel/mkl101/include/ and the example sources are in /opt/intel/mkl101/examples/ .

Unless you have a nonstandard installation, these paths, modified to suit your version of MKL and machine architecture, should work.

Erich,

It looks like you use incorrectly g++.
In order to run dftc examples please use make in the directory/opt/intel/mkl/10.2.2.025/examples/dftc/

% make help
Usage: make {libia32|soia32|libintel64|sointel64} [function=name]
[compiler=compiler_name] [interface=interface_name] [threading=threading_name]
[omp=omp_name] [parallel=parallel_name]

name - function name. Please see dftc.lst file

compiler_name - can be gnu, pgi or intel. Default value is intel.
Intel C Compiler as default

omp_name - can be iomp5 if parallel=intel or
can be iomp5 or gomp if parallel=gnu or
can be pgmp if parallel=pgi.
Default value is iomp5.

interface_name - can be lp64 or ilp64 for intel64. Default value is lp64.

parallel_name - can be intel (default value), pgi (only if compiler=pgi) or
gnu (if compiler=gnu).

threading_name - can be parallel or sequential. Default value is parallel.

Hi Victor

Thank you for your help.

That's compiling now, thanks.
