如何在命令行上将Intel fortran编译器与MKL结合使用 [英] How to use Intel fortran compiler with MKL on command line
问题描述
我刚刚安装了Fortran OS X *（学生版）的英特尔®Parallel Studio XE Composer版。它带有数学内核库，这就是我购买它的原因。我很难开始MKL。这是我逐步完成的操作。
I've freshly installed the Intel® Parallel Studio XE Composer Edition for Fortran OS X* (student version). It comes with the Math Kernel Library, which is why I bought it. I'm having a hard time getting started with MKL. Here's what I've done step-by-step.
1）安装了用于Fortran OS X *的英特尔®Parallel Studio XE Composer Edition（没问题）。我可以使用 ifort 运行'hello world'脚本，并在末尾使用 -mkl 链接命令问题（尚未调用任何mkl命令）。
1) Installed Intel® Parallel Studio XE Composer Edition for Fortran OS X* (no problem). I can run a 'hello world' script using ifort and throw the -mkl link command on at the end with no problem (not calling any mkl commands just yet).
2）之后这些说明我使用intel提供的脚本（精确地位于opt / intel / bin中）设置了环境变量。我有intel 64位体系结构（根据 ifort -V ），所以我使用 bash mklvars.sh intel64 mod ilp64 。它运行无错误（或任何输出）。
2) Following these instructions I set my environment variables using a script provided by intel (located in opt/intel/bin to be precise). I have the intel 64-bit architecture (according to ifort -V) so I use bash mklvars.sh intel64 mod ilp64. It runs without error (or any output).
3）我编写了以下代码，以使用MKL的 gemm 命令。只需将2个矩阵相乘即可。
3) I write the following code to use MKL's gemm command for fortran95. Just multiplying 2 matrices.
program test
implicit none
real, dimension(2,2) :: testA, testB, testC
testA = 1
testB = 1
testC = 0 ! I don't think I need this line, but it shouldn't matter
call gemm(testA, testB, testC)
write(*,*) testC
end program test
4）我使用 ifort进行编译test_mkl.f90 -o测试-mkl 。我收到以下错误：
4) I compile with ifort test_mkl.f90 -o test -mkl. I get the following error:
Undefined symbols for architecture x86_64:
"_gemm_", referenced from:
_MAIN__ in ifortSTVOrB.o
ld: symbol(s) not found for architecture x86_64
未找到符号5）我尝试 ifort test_mkl.f90 -o test -L / opt / intel / mkl / lib -mkl 并得到相同的结果。
5) I try ifort test_mkl.f90 -o test -L/opt/intel/mkl/lib -mkl and get the same result.
我注意到很多使用MKL的人都以 USE mkl95_blas（仅限：gemm ）开始他们的代码，所以我把上面两个示例中都不隐含并得到：
I notice a lot of people using MKL begin their code with USE mkl95_blas, ONLY: gemm, so I put that in above implicit none in both of the above examples and get:
test_mkl.f90(4): error #7002: Error in opening the compiled module file. Check INCLUDE paths. [MKL95_BLAS]
USE mkl95_blas, ONLY: gemm
--------^
test_mkl.f90(12): error #6406: Conflicting attributes or multiple declaration of name. [GEMM]
call gemm(testA, testB, testC )
---------^
test_mkl.f90(4): error #6580: Name in only-list does not exist. [GEMM]
USE mkl95_blas, ONLY: gemm
--------------------------^
compilation aborted for test_mkl.f90 (code 1)
关于问题是什么或如何解决的任何想法？我已经成功使用MKL在XCODE中运行一个简单的脚本，因此绝对是我在做的事情，而不是我的安装。
Any ideas as to what the problem is or how to fix this? I have successfully run a simple script in XCODE using MKL, so it's definitely something I'm doing and not my installation.
推荐答案
文档告诉您在提供的Compilervars.sh脚本上使用 source命令来使所有资源可用。例如：
The documentation tells you to use the "source" command on the provided compilervars.sh script to make all the resources available. For example:
源//bin/compilervars.sh
source //bin/compilervars.sh
这会将MKL添加到包含和库中路径，以便编译器和链接器可以找到它们。如果您需要更多帮助，请在 https://software.intel.com/zh-cn/forums/intel-fortran-compiler-for-linux-and-mac-os-x 您可以在< a href = https://software.intel.com/en-us/forums/intel-math-kernel-library rel = nofollow> https://software.intel.com/en-us/forums/英特尔数学内核库
This will add MKL to the include and library paths so that the compiler and linker can find them.
