Compiling R 3.0.2 with MKL

Benjamin_D_1 — Thu, 27 Feb 2014 16:59:55 GMT

I'm not sure if R compiled correctly with MKL:

When I do ldd on R I don't see any reference to MKL

Some info on how I compiled R with MKL:

This was the actual command I ran to configure R:

./configure --enable-R-shlib --enable-threads=posix --with-lapack --with-blas=-fopenmp -m64 -I/opt/intel/composer_xe_2013_sp1.0.080/mkl/include -L/opt/intel/composer_xe_2013_sp1.0.080/mkl/lib/intel64 -lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lpthread -lm

In my config.log file I do see:

configure:29696: checking whether double complex BLAS can be used
configure:29767: result: yes

However, right after that I see:

configure:29787: checking whether the BLAS is complete
conftest.c: In function 'blas_set':

Did you look at the final link command? Mkl_gf is for gfortran. You didn't say you intended to mix gfortran and icc.

I tried to re-install but

Benjamin_D_1 — Fri, 28 Feb 2014 02:01:23 GMT

I tried to re-install but this time with intel compiler (and correct link command) but I still don't have MKL linked! This was my 2nd attempt at config: ./configure --with-blas=-DMKL_ILP64 -openmp -I/opt/intel/composer_xe_2013_sp1.2.144/mkl/include -L/opt/intel/composer_xe_2013_sp1.2.144/mkl/lib/intel64 -lmkl_intel_ilp64 -lmkl_core -lmkl_intel_thread -liomp5 -lpthread -lm --with-lapack

Benjamin,

Benjamin,

Please follow these steps for building with Intel compilers and Intel MKL.

$export AR=”xiar”

$export LD=”xild”

Set the Intel MKL and OpenMP library paths

$MKL_LIB_PATH=’/opt/intel/composer_xe_2013_sp1/mkl/lib/intel64’

$OMP_LIB_PATH=’/opt/intel/lib/intel64’

$export LD_LIBRARY_PATH=${MKL_LIB_PATH}:${OMP_LIB_PATH}

$MKL=" -L${MKL_LIB_PATH} -L${OMP_LIB_PATH} -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread"

Edit config.site by making changes for C/C++ and FORTRAN compilers and its options related lines as shown below:

CC=’icc –std=c99’

CFLAGS=’-O3 –ipo –xavx –openmp’

F77=’ifort’

FFLAGS=’-O3 –ipo –xavx –openmp’

CXX=’icpc’

CXXFLAGS=’-O3 –ipo –xavx –openmp’

$./configure --with-blas="$MKL" --with-lapack

Check the config.log to see if Intel® MKL was working during the configuration test.

configure:29075: checking for dgemm_ in -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread

configure:29096: icc -std=c99 -o conftest -O3 -ipo -openmp -xHost -I/usr/local/include -L/usr/local/lib64 conftest.c -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lifport -lifcoremt -limf -lsvml -lm -lipgo -liomp5 -lirc -lpthread -lirc_s -ldl -lrt -ldl -lm >&5

conftest.c(210): warning #266: function "dgemm_" declared implicitly

configure:29096: $? = 0

configure:29103: result: yes

configure:29620: checking whether double complex BLAS can be used

configure:29691: result: yes

configure:29711: checking whether the BLAS is complete

Now, run make to build and install R with the Intel® Compiler and Intel® MKL:

$make && make install

To check the correct installation, run ldd and it should show something like below.

$ ldd ./bin/exec/R

linux-vdso.so.1 => (0x00007fff2a1ff000)

libmkl_intel_lp64.so => /opt/intel/composer_xe_2013_sp1.0.080/mkl/lib/intel64/libmkl_intel_lp64.so (0x00007f7d89bf9000)

Benjamin_D_1 — Fri, 28 Feb 2014 15:14:55 GMT

I figured out the previous error. When I copy pasted your commands from this website the encoding on the ' - ' character did not get translated correctly. Very difficult error to catch!

Vipin,

Benjamin_D_1 — Fri, 28 Feb 2014 19:48:09 GMT

Vipin,

I am still having a problem with the install. After I do make, I do a make check to see if make was okay and I get the following error:

running code in 'reg-packages.R' ...make[3]: *** [reg-packages.Rout] Error 1

when I look at tests/reg-packages.Rout.fail I see:

unable to load shared object '/home/benjamin/R/x86_64-unknown-linux-gnu-library/3.0/lattice/libs/lattice.so':
libR.so: cannot open shared object file: No such file or directory

I figured out the problems. I

Benjamin_D_1 — Fri, 28 Feb 2014 20:26:42 GMT

I figured out the problems. I had some leftover libraries present in my home directory from previous R installs. Getting rid of those and re-compile from source made everything work. Thank you!
