Problems builing elemental with Intel MKL

[agra...@gfz-potsdam.de]

Hello!

I'm trying to build Elemental on cluster using Intel Compiler + Intel MKL + IntelMPI toolchain. 

Using following cmake command:

cmake -D CMAKE_INSTALL_PREFIX=/home/ag/lib/elemental -D CMAKE_CXX_COMPILER=mpiicc -D CMAKE_C_COMPILER=mpiicc -D CMAKE_Fortran_COMPILER=mpiifort -D MATH_LIBS="-L/usr/local/opt/intel/composer_xe_2011_sp1.6.233/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_core -lm" ..

I end up with error:

-- Using user-defined MATH_LIBS=-L/usr/local/opt/intel/composer_xe_2011_sp1.6.233/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_core -lm

-- Looking for daxpy

-- Looking for daxpy - not found

-- Looking for daxpy_

-- Looking for daxpy_ - not found

CMake Error at CMakeLists.txt:316 (message):

  Could not determine BLAS format.

At the same time nm tells me there is BLAS:

elemental/build> nm /usr/local/opt/intel/composer_xe_2011_sp1.6.233/mkl/lib/intel64/libmkl_intel_lp64.so | grep daxpy                                                                                                                 0000000000113b70 T cblas_daxpy

0000000000113bb0 T cblas_daxpyi

0000000000103c30 T daxpy

0000000000103c30 T daxpy_

0000000000100540 T daxpyi

0000000000100540 T daxpyi_

                 U mkl_blas_daxpy

                 U mkl_blas_daxpyi

Any ideas why cmake can not find BLAS?

Thanks.

Can you post CMakeFiles/CMakeError.log?  I suspect that you just didn't provide a sufficient set of MKL libs, which is easy to do because Intel makes it as hard as possible to link MKL.

Thanks,

Jeff

Hi Jeff,

This question was actually answered here:
https://groups.google.com/forum/?fromgroups=#!topic/elemental-maint/ghgc_RrZXXg

There was a bit of confusion because I had just created elemental-maint.

Yeah, I saw that too late. I do not understand why the subject changed.
