Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so.

malik__tania — Mon, 21 Dec 2015 15:35:31 GMT

I have installed Fupermod software with MKL support. It installed correctally. But when I run the program it give me that error

Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so.

Can you please let me know what I am doing wrong?

When you attempted to run it,

mecej4 — Mon, 21 Dec 2015 15:42:00 GMT

When you attempted to run it, did you do so in a command shell after sourcing compilervars.sh or one of its siblings? If not, you may need to see to it that the MKL shared libraries are accessible along LD_LIBRARY_PATH (or the equivalent that pertains to your OS). What do you see when you run the following command?

echo $LD_LIBRARY_PATH

malik__tania — Mon, 21 Dec 2015 15:48:13 GMT

Yes i did source. Also i add this line in my .bashrc file.

source /opt/intel/compilers_and_libraries_2016.0.109/linux/mkl/bin/mklvars.sh intel64

I am running my program on ubuntu OS.

The output of echo $LD_LIBRARY_PATH is:

There are only two

mecej4 — Mon, 21 Dec 2015 16:36:12 GMT

There are only two directories in that list that pertain to MKL, and those are

/opt/intel/compilers_and_libraries_2016.0.109/linux/mkl/lib/intel64

and

/home/tania/.openmpi/lib//home/tmalik/intel/composer_xe_2013_sp1.0.080/mkl/lib/intel64

Do you have the libraries libmkl_avx2.so or libmkl_def.so in those directories?

I I have found these file in

malik__tania — Mon, 21 Dec 2015 16:45:44 GMT

I I have found these file in this folder:

How can I add this?

The output of echo $LD_LIBRARY_PATH is:

The MIC_LD_LIBRARY_PATH shows me this output:

tania@tania-Latitude-E5540:~$ echo $MIC_LD_LIBRARY_PATH
/opt/intel/compilers_and_libraries_2016.0.109/linux/tbb/lib/mic:/opt/intel/compilers_and_libraries_2016.0.109/linux/compiler/lib/mic:/opt/intel/compilers_and_libraries_2016.0.109/linux/mkl/lib/mic:/opt/intel/compilers_and_libraries_2016.0.109/linux/tbb/lib/mic:/opt/intel/compilers_and_libraries_2016.0.109/linux/compiler/lib/mic:/opt/intel/compilers_and_libraries_2016.0.109/linux/mkl/lib/mic

That makes the problem clear.

mecej4 — Mon, 21 Dec 2015 17:49:45 GMT

That makes the problem clear. The new version of Parallel Studio uses intel64_lin as <arch>, whereas that used to be <intel64> in previous versions. The MKL team should resolve this but, as a temporary solution, you can send the output of "echo $LD_LIBRARY_PATH" to a file (echo $LD_LIBRARY_PATH > ldlibpath.txt), edit the file to replace "intel64" by "intel64_lin" throughout, and issue the command

export LD_LIBRARY_PATH=<_insert_here_the_contents_of_ldlibpath.txt_>

The drawback of this is that you have to issue issue this command each time that you open a shell window to use the compiler and MKL. The better solution is for the start-off scripts compilervars.sh, etc., to be fixed with the new directory names, but the MKL team is to advise on this.

Hi

malik__tania — Mon, 21 Dec 2015 18:03:03 GMT

I did exactly as you wrote

The output of echo $LD_LIBRARY_PATH after that is:

But still I got the same error:

All the shared library files

mecej4 — Mon, 21 Dec 2015 19:05:00 GMT

All the shared library files have execute permissions set, and the directory containing them has execute permissions set, so there is no problem there.

Sorry, I have run out of suggestions at this point.

Hello,

Ying_H_Intel — Tue, 22 Dec 2015 01:11:05 GMT

Hello,

Not sure if it is related to the environment. Could you please try

1) > ldd your application, what the output?

2) you mentioned MIC, so have you xeon phi coprocessor in your system? does the application run on the xeon phi?

3) there are some example (fortran or C sample) under MKL install directory. Could you please unzip one of them and run one of them

for example,

>/mkl_example/cblas

> make libintel64 function=cblas_dgemm

let us know the output of the sample program.

4) or is it possible to LD_PRELOAD=/opt/intel/compilers_and_libraries_2016.0.109/linux/mkl/lib/intel64_lin/libmkl_def.so, then run your application.

Here is a similiar issue for your reference: https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/600019

Here are the results of 4 options that you suggested:

(1) tania@tania-Latitude-E5540:~/openform_fupermod_test$ ldd ~/build_fupermod/mkl/tools/builder
not a dynamic executable

2) you mentioned MIC, so have you xeon phi coprocessor in your system? does the application run on the xeon phi?

I have no idea about it. I just install MKL to use in cblas.

(3) Examples are working

I am attaching Fupermod makefile.in and configure.ac file

you can check the compile option of MKL in case if you want see.

Hi Tania,

Ying_H_Intel — Wed, 23 Dec 2015 02:11:39 GMT

Hi Tania,

Thanks for the reply. so we can get

1) MKL work in simple command environment, but can't work in the mpirun

>mpirun -np 4 -machinefile machinefile ~/build_fupermod/mkl/tools/builder -l

~/build_fupermod/mkl/routines/mxm/.libs/libmxm_1d.so -U2000 -s100

2) ~/build_fupermod/mkl/routines/mxm/.libs/libmxm_1d.so are linked mkl librarylibintel_libmkl_intel_lp64.so or

ibmkl_gnu_thread.so libmkl_core.so. and libintel_libmkl_intel_lp64.so or ibmkl_gnu_thread.so or libmkl_core.so

internally invokes libmkl_avx2.so or libmkl_def.so. Because in my application I don't need them directaly.

So the solution is either remove the dependency or to make sure the mpirun environment can invoke the libmkl_avx2.so or

libmkl_def.so as command line case.

Could you rebuild the Fupermod or libmxm_1d.so with static mkl library (for example, libmkl_intel_lp64.a, libmkl_gnu_thread.a libmkl_core.a, not .so), which will not ask the mkl dynamic libary (libmkl_avx2.so and libmkl_def.so)

other ways, may be -rpath option or add –no-as-needed as https://software.intel.com/en-us/forums/intel-math-kernel-
