Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers. Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers.

Hi all,

I am trying to compile a tensor library from source and cythonize the code. The code is taken from a github repository: https://github.com/cyclops-community/ctf .Unfortunately, it seems that the cythonized code is throwing me errors when I ran the test cases. I pass the linkers by running the following command in my configure files:

./configure --no-static LD_LIB_PATH="-L$MKLROOT/lib/intel64/" LD_LIBS="-lmkl_scalapack_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_lp64  -lpthread -lm" CXXFLAGS="-O3 -no-ipo"

I have attached the configure file here. Does anyone know what error is implied by " Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers. Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers. ". Googling this shows me it might be because I have a non-dynamic version of mkl_blacs_intelmpi_lp64. I do have it in my directory though.

Best,
Adrian

MKL Linker Adviser recommends to use this link line: -L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_scalapack_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_lp64 -liomp5 -lpthread -lm -ldl

Hi there, thanks for the reply. I changed configure to:
/configure --no-static LD_LIB_PATH="-L$MKLROOT/lib/intel64/ -Wl,--no-as-needed" LD_LIBS="-lmkl_scalapack_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_lp64 -liomp5 -lpthread -lm -ldl" CXX='mpiicc' CXXFLAGS="-O3 -no-ipo"

Unfortunately, I am still having the same error:

could you try to re-link with MKL 2019?

[Tan__Adrian]

So this is a cluster and I dont have the administrative rights to install that. What I did was I load with a compiler from 2018 that has a MKL 2018 associated with it. The compiler version is:

icc (ICC) 18.0.1 20171018
 

I then configure as follows: 

/configure --no-static LD_LIB_PATH="-L$MKLROOT/lib/intel64/ -Wl,--no-as-needed" LD_LIBS="-lmkl_scalapack_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_lp64 -liomp5 -lpthread -lm -ldl" CXX='mpiicc' CXXFLAGS="-O3 -no-ipo"

This time, the compiler fails to build the dynamic library. The error log is below:

Hi all,

I managed to get access to another cluster that has an intel compiler from 2019 that should link with intel MKL 2019. I still received the same error:

 

Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers.

Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers.

Any suggestions?

Best,
Adrian
