This is how we build R with the Intel compilers and MKL on CentOS 6.x, with different versions of R (latest version: 3.2.1) and Intel compilers (latest version: 2015.3) on Intel SandyBridge CPUs: fast="-ip -O3 -opt-mem-layout-trans=3 -xHost -mavx" export CC="icc" export CFLAGS="$fast -wd188 -fp-model precise" export F77="ifort" export FFLAGS="$fast -fp-model precise" export CXX="icpc" export CXXFLAGS="$fast -fp-model precise" export FC="ifort" export FCFLAGS="$fast -fp-model precise" ./configure --prefix=$destdir --with-blas='-mkl=parallel' --with-lapack --enable-BLAS-shlib Thank you for this configuration. Nothing about openmp? What about my cited missing librairies. libmkl_intel_lp64.so libmkl_intel_thread.so libmkl_core.so Any idea why they are not listed by the ldd command? ## Notes (they might not be true anymore): ## -static and -ipo break compilation ## -no-prec-div breaks make check ## -fp-model precise is needed for make check ## -wd188 removes a lot of warnings (see R Inst. & Adm. manual) We have successfully used this setup for a couple of years now. -- Regards, Bjørn-Helge Mevik ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
