将Ipopt与Intel MKL关联 [英] Linking Ipopt with Intel MKL

问题描述

我正在尝试将Ipopt与Intel MKL(说明).

I'm trying to link Ipopt with Intel MKL (instructions).

英特尔的链接顾问建议:

链接行:

 -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_ilp64.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a -Wl,--end-group -lpthread -lm -ldl

编译器选项:

 -DMKL_ILP64 -qopenmp -I${MKLROOT}/include

我尝试使用以下方法配置Ipopt:

I try to configure Ipopt with:

../configure CXX=icpc CC=icc F77=ifort --with-blas=" -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_ilp64.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a -Wl,--end-group -lpthread -lm -ldl" CXXFLAGS=" -DMKL_ILP64 -qopenmp -I${MKLROOT}/include"

这最终失败，表明:

checking whether user supplied BLASLIB=[text above]  does not work

推荐答案

首先，您需要确保正确安装和配置了MKL，如下所示.

First you need to make sure that MKL is correctly installed and configured as shown here.

https://软件.intel.com/en-us/get-started-with-parallel-studio-xe-for-linux

一种永久的方法是将以下行放入 .bashrc 或 .profile

A permanent way is to put the following line in your .bashrc or .profile

source /opt/intel/parallel_studio_xe_2016.<##>.<###>/psxevars.sh intel64

您可以使用以下cmdline检查MKL是否已准备就绪.它应该显示有效的MKL安装目录.

You could use the following cmdline to check if MKL is ready. It should display the valid MKL installation dir.

$ echo $MKLROOT

如果您使用的是MKL链接行顾问程序，为什么不完全按照说明进行操作?我注意到您错过了链接选项中的OpenMP lib -liomp5 和整个编译选项.

我可以通过以下方式使用单个动态MKL构建Ipopt:

I can build Ipopt with single dynamic MKL by

$ mkdir build
$ cd build
$ ../configure --with-blas=' -Wl,--no-as-needed -L${MKLROOT}/lib/intel64  -lmkl_rt -lpthread -lm -ldl' CFLAGS=' -m64 -I${MKLROOT}/include' CXXFLAGS=' -m64 -I${MKLROOT}/include'

，并带有动态MKL，

$ mkdir build
$ cd build
$ ../configure --with-blas='-Wl,--no-as-needed -L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_core -lmkl_intel_thread -liomp5 -lpthread -lm -ldl' CFLAGS=' -m64 -I${MKLROOT}/include' CXXFLAGS=' -m64 -I${MKLROOT}/include'

但是它不适用于静态MKL.

But it does not work with static MKL.

以上设置仅适用于gcc编译器.

The above settings only work with gcc compiler.

具有icc编译器的动态MKL也可以使用以下设置.

Dynamic MKL with icc compiler also works with the following setting.

$ mkdir build
$ cd build
$ ../configure --with-blas=' -L${MKLROOT}/lib/intel64 -lmkl_intel_ilp64 -lmkl_core -lmkl_intel_thread -lpthread -lm -ldl' CFLAGS=' -DMKL_ILP64 -qopenmp -I${MKLROOT}/include' CXXFLAGS=' -DMKL_ILP64 -qopenmp -I${MKLROOT}/include' CC=icc CXX=icpc
