help MPI support on dual CPU server

Post by timber » Fri Dec 12, 2014 2:29 am

hi, I have a lenovo D20 server, dual CPUs and 12 cores.
The OS is centos7, with epel repo
I configure all the requeirements from vendor and epel repo, and I can run through the tests under serial mode.

but when I compile with MPI support, it always failed. the terminal message is:

I was confused. if there is something or tricks for a dual CPUs configuration?

Hi,

two questions and one idea…

1) what is the content of the file : /root/.abinit/build/c64.ac

2) results of commands :

Code: Select all

mpicc -show
mpicc --version
mpif90 -show
mpif90 --version


3) try to put the mpi "compiler" at the beginning of the PATH variable :

Code: Select all

export PATH=/usr/lib64/openmpi/bin:$PATH
export LD_LIBRARY_PATH=/usr/lib64/openmpi/lib:$LD_LIBRARY_PATH
./configure --enable-mpi --enable-mpi-io

the configuration file for centos 64
run under vmware workstation 10

I have tried run another cenos7 , in real mode. The message is the same, corrupt on mpicc
The host OS is windows server 2012, I have to shared it with other colleagues.

Hi,

I found a "little" error in the c64.ac file

Code: Select all

CC = "/usr/lib64/openmpi/bin/mpicc

instead of

Code: Select all

CC="/usr/lib64/openmpi/bin/mpicc"


I configured a machine under CentOS 7 with openmpi/ffw3 and with a .ac file ( without some fallbacks in the first time ) :

Code: Select all

enable_64bit_flags="yes"
enable_debug="yes"
prefix="/opt/abinit4.10gcc48openMp"
CC="/usr/lib64/openmpi/bin/mpicc"
FC="mpif90"
enable_mpi="yes"
enable_mpi_io="yes"
with_mpi_incs="-I/usr/include/openmpi-x86_64"
with_mpi_libs="-L/usr/lib64/openmpi/lib -lmpi"
with_fft_libs="-L/usr/lib64/ -lfftw3 -lfftw3f"
with_dft_flavor="libxc"
with_trio_flavor="none"
enable_fallbacks="yes"
enable_openmp="yes"

and with a environment variables ( part ) :

Code: Select all

PATH=/usr/lib64/openmpi/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:~/bin
LD_LIBRARY_PATH=/usr/lib64/openmpi/lib:


the "./configure" and "make mj4" work !

I revised the configuration file. but the script output the same error message.
I think I had use this setting before.

attachment is the config.log of openompi with intel compiler

SO the openmpi works.

but why the detection in abinit failed
