dear all,

I am new in openMPI world and in general in parallelization.

I have some problems with configuration of openMPI in my laptop.

I have read your FAQ and I tried to google the problem but I was not able to solve it.The problem is:
I have downloaded the openmpi-1.6.3, unpacked it Then I have installed on my pc intel icc and icpc.when I run:./configure CC=icc CXX=icpc F77=ifort FC=ifort
I get:

*** Startup tests
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for gcc... icc
checking whether the C compiler works... no
configure: error: in `/home/diedro/Downloads/openmpi-1.6.3':configure:
error: C compiler cannot create executables
See `config.log' for more details
diedro@diedro-Latitude-E6420:~/Desktop/Downloads/openmpi-1.6.3$

I do not understand why. I did a simple hello project with icc and it works.(in attachment you can fiend the config.log)

I think that it is some problem with bash file:

PATH="/opt/intel/bin/compilervars.sh intel64$PATH"
source /opt/intel/bin/compilervars.sh intel64
source /opt/intel/mkl/bin/mklvars.sh intel64 mod lp64
export PATH

but I don not know what because as I told you when I run a simple hello project with icc and it works

Really thanks for any help

dear all,
My fault in the new version you need to do exactly like the FAQ told you and to not use icc or ifort o gcc, simple:


shell$ gunzip -c openmpi-1.6.3.tar.gz | tar xf -

shell$ cd openmpi-1.6.3

shell$ ./configure --p

Hi dedro

i have download openMPI 1.6.3 and configure with the same options as you, than i compile it with make under openSUSE 12.2 M2 x86_64 with Kernel 3.6.7 and Intel Parallel Studio XE 2013 64 Bit update 1 for linux without any Problems.
i think your main problems are the wrong environment settings in your bash file(s), here a sample of my .bashrc

export PATH=$PATH:/opt/cuda-5.0:/usr/local/cuda-5.0/bin:/opt/intel/composer_xe_2013.1.117/bin/intel64:/opt/intel/composer_xe_2013.1.117/ipp/bin/intel64:/opt/composer_xe_2013.1.117/mkl/bin/intel64:/opt/intel/impi/4.1.0.024/intel64/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda-5.0/common/lib/linux/x86_64:/usr/local/cuda-5.0/lib:/usr/local/cuda-5.0/lib64:/opt/intel/composer_xe_2013.1.117/compiler/lib/intel64:/opt/intel/mkl/lib/intel64:/opt/intel/ipp/lib/intel64:/opt/intel/tbb/lib/intel64:/opt/intel/impi/4.1.0.024/intel64/lib
export IPPROOT=/opt/intel/composer_xe_2013.1.117/ipp

i use this settings for all users and any user can compile the openMPI-1.6.3 without any problems

cheers
Franz

Dear Franz,
I do not understand.
do you simple run "./configure --p"? this means that you use the default gcc,g++ and gnufort to compile openMPI, is it right?
in your bash I do not understand especially "export IPPROOT=/opt/intel/composer_xe_2013.1.117/ipp"
I use


PATH="/opt/intel/bin/compilervars.sh intel64$PATH"

source /opt/intel/bin/compilervars.sh intel64

source /opt/intel/mkl/bin/mklvars.sh intel64 mod lp64

export PATH

In this way when I compile a simple hello project it works with icc or ifort. ./configure
././configure CC=icc F77=ifort FC=ifort
configure CC=icc F77=ifort FC=ifort does not work.
what do you think?

thanks

Please follow openmpi faq about configure and how to ask questions. Does reported error relate to failure to specify CXX=icpc?

dear TimP and Franz,

I have followed the FAQ. In the FAQ the say that the most common problem is that most people use icc instead of icpc for c++ part. The intel user need to compile as:


shell$ ./configure CC=icc CXX=icpc F77=ifort FC=ifort ...

I wrote to openMPI mailing list, they told me thar is a icc problem but when I run a simple hello project it runs.

Or it is an installation problem. I have installed intel fortran and intel c\c++ in the same default folder, is it correct?

thanks

okay

this is correct, default the Intel installation program installs the c/c++ and the fortran compiler in he same folder.

i have use this type of environment setting for dedicade setting the environment

the IPPROOT is the setting for Integrated Performancd Primitive short IPP environment,

i have include this settings in each .bashrc for any user, you can for modify as you need for each user

other: this is the result from ./configure --p:

linux-cuda:/ibm_supercomputing/openmpi-1.6.3 # ./configure --p
configure: error: missing argument to --prefix
linux-cuda:/ibm_supercomputing/openmpi-1.6.3 #

i have with my settings no problems with the ICC and his components such as MKL, IPP the debugger IDB or the Profiler
on my workstation i permanent use my CUDA SDK 5.0 + gcc-4.6.3 and the Intel C/C++ for performance critical standard c/c++ apps.

tip: check after reboot your environment with follows:

echo $PATH = info PATH settings
echo $LD_LIBRARY_PATH = info LIB-PATH Settings

when you find in both the settings for the Intel c/c++ and fortran then normally all works correct

cheers
Franz
