I am having a very weird problem with mpifort that I cannot understand.
I am building OpenMPI 1.10.3 with GCC 5.4.0 with EasyBuild and everything goes 
fine until I try to use mpifort to build any MPI Fortran code, which fails with 
the error log you see below.
The thing I do not understand is why the linker searches for libgfortran.so in 
/usr/lib64 instead of the actual GCC installation path,  where the file is 
actually located. Both LD_LIBRARY_PATH and LIBRARY_PATH contain the correct path 
to the library. The gfortran compiler works correctly for compiling serial code.

Attached you can also find the ourput of the same command with LD_DEBUG=1.
Any idea what is going wrong?


The place the link-time link editor ld searches for still seems to be /usr/lib64 
first.



$ ll /accre/arch/easybuild/software/Core/GCCcore/5.4.0/lib64/libgfortran.so
lrwxrwxrwx 1 buildbot buildbot 20 Nov 27 18:44 
/accre/arch/easybuild/software/Core/GCCcore/5.4.0/lib64/libgfortran.so -> 
libgfortran.so.3.0.0


So I assume you mean to invoke a gfortran binary located at

/accre/arch/easybuild/software/Core/GCCcore/5.4.0/bin/gfortran

?


$ mpifort multitask_mpi.f90


What does "mpifort -show" report what gfortran command is used? If the first 
part is simply gfortran, what does "which gfortran" print?


/accre/arch/easybuild/software/Compiler/GCCcore/5.4.0/binutils/2.26/bin/ld.gold: 
error: cannot open /usr/lib64/libgfortran.so: No such file or directory


so obviously your build finds something named libgfortran.so in /usr/lib64 but 
cannot use it. Is it a defunct symbolic link?



/tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined  > 
reference to '_gfortran_date_and_time'

[...]
These are just followup errors from not being able to find the correct 
libgfortran.

Re: [OMPI users] OMPI 2.1.2 and SLURM compatibility

2017-11-29 Thread r...@open-mpi.org

Hi Bennet

I suspect the problem here lies in the slurm PMIx plugin. Slurm 17.11 supports 
PMIx v2.0 as well as (I believe) PMIx v1.2. I’m not sure if slurm is somehow 
finding one of those on your system and building the plugin or not, but it 
looks like OMPI is picking up signs of PMIx being active and trying to use it - 
and hitting an incompatibility.

You can test this out by adding --mpi=pmi2 to your srun cmd line and see if 
that solves the problem (you may also need to add OMPI_MCA_pmix=s2 to your 
environment as slurm has a tendency to publish envars even when they aren’t 
being used).

Re: [OMPI users] mpifort cannot find libgfortran.so at the correct path

2017-11-29 Thread Vanzo, Davide

Thank you Åke, Reuti and Thomas for your replies.

Just to clarify. The reason why /usr/lib64/libgfortran.so does not exist is 
intentional because on our cluster we use a minimal CentOS installation and all 
libraries are provided through the software stack built via EasyBuild on a 
non-system path.

The output of `mpifort -show` shows the correct executable for `gfortran` ( I 
checked with `which gfortran`):

$ mpifort multitask_mpi.f90 -show
gfortran multitask_mpi.f90 
-I/accre/arch/easybuild/software/Compiler/GCC/5.4.0-2.26/OpenMPI/1.10.3/include 
-I/accre/arch/easybuild/software/Compiler/GCC/5.4.0-2.26/OpenMPI/1.10.3/lib 
-L/usr/lib64 -Wl,-rpath -Wl,/usr/lib64 -Wl,-rpath 
-Wl,/accre/arch/easybuild/software/Compiler/GCC/5.4.0-2.26/OpenMPI/1.10.3/lib 
-Wl,--enable-new-dtags 
-L/accre/arch/easybuild/software/Compiler/GCC/5.4.0-2.26/OpenMPI/1.10.3/lib 
-lmpi_usempif08 -lmpi_usempi_ignore_tkr -lmpi_mpifh -lmpi


If I try to compile the source code with the explicit command after removing 
the `-L/usr/lib64` flag it compiles, links and executes correctly.

For the sake of testing I have built OpenMPI in the same exact way on another 
machine with the same minimal OS. The only difference (at least that I am aware 
of) is the root prefix of the installation path. In this case it works 
correctly even without removing `-L/usr/lib64`.

To try to better understand, I have launched `mpifort -v`. Below you can find 
the paths in COMPILER_PATH and LIBRARY_PATH for both systems.
Take into account that on the broken system `/accre/arch` is a symlink to 
`/gpfs22/accre/optimized/haswell`. But I do not see how this can be the 
problem...

Re: [OMPI users] mpifort cannot find libgfortran.so at the correct path

2017-11-29 Thread Jeff Squyres (jsquyres)

FWIW, adding -L/usr/lib or -L/usr/lib64 is generally considered Bad, because it 
may usurp the default linker path order.

I note that you're using Open MPI 1.10.3 -- if you're unwilling/unable to 
upgrade to Open MPI 3.0.x, could you upgrade to Open MPI 1.10.7?  We may well 
have fixed the issue in that time (i.e., do not have mpifort add -L/usr/lib64 
to the command line).

Re: [OMPI users] mpifort cannot find libgfortran.so at the correct path

2017-11-29 Thread Vanzo, Davide

Jeff,

Thanks for your feedback.

Although tempting, changing the version of OpenMPI would mean a significant 
amount of changes in our software stack. Hence I would like to find out what 
the problem is and hopefully its solution.

Where is the -L/usr/lib64 injected? Is there a way to patch the code so that it 
does not get added to the list of options to gfortran?

Understood.

FWIW: the only differences between 1.10.3 and 1.10.7 were bug fixes (including, 
I'm assuming -- I haven't tested myself -- this -L issue).  Hypothetically, it 
should be a fairly painless upgrade.

It's injected pretty deep inside configure.

We might be able to spelunk through the git logs to find the commit that fixes 
this issue and you could apply that as a patch, but it might be easier to just 
manually patch up the wrapper compiler data file after the build.

Specifically, it looks like OMPI 1.10.3 is installing faulty values 
$prefix/share/openmpi/*-wrapper-data.txt.  You can easily edit these files 
directly and remove the erroneous -L/usr/lib64.  If you're unable to upgrade to 
1.10.7, patching the installed *-wrapper-data.txt files is probably your best 
bet.

Re: [OMPI users] mpifort cannot find libgfortran.so at the correct path

2017-11-29 Thread Vanzo, Davide

Jeff,

Thanks for pointing me in the right direction. I have finally figured out what
the problem is.

On the cluster we install Slurm via RPMs and the PMI/PMI2 libraries are in
/usr/lib64. Hence the -L/usr/lib64 flag is the effect of the --with-pmi=/usr
configure flag. The good thing is that even by omitting it the final binary is
correctly linked to the PMI libraries.

And the reason why in the other system I tested the build it was working is
because there is no Slurm installed in it.

Re: [OMPI users] mpifort cannot find libgfortran.so at the correct path

2017-11-29 Thread Jeff Squyres (jsquyres)

Ah.  You might also try just --with-pmi (instead of --with-pmi=/usr).  That 
might avoid adding the errant -L/usr/lib64 to the wrapper data files.

Our configure nomenclature is (from README):

-
Note that for many of Open MPI's --with- options, Open MPI will,
by default, search for header files and/or libraries for .  If
the relevant files are found, Open MPI will built support for ;
if they are not found, Open MPI will skip building support for .
However, if you specify --with- on the configure command line and
Open MPI is unable to find relevant support for , configure will
assume that it was unable to provide a feature that was specifically
requested and will abort so that a human can resolve out the issue.
