Yambo 4.2.1, ompi_mpi_comm_world error

[Fabiof]

Dear all,

I am having some problem when installing yambo 4.2.1.

This is my config command:
./configure --enable-openmpi --with-iotk-path="/home/fabiof/bin/espresso-5.4.0/iotk" --with-p2y-version=5.4 --with-fft-libdir="/usr/local/lib/" --with-fft-includedir="/usr/local/include/" --with-blas-libs="-L//opt/intel/composer_xe_2013.1.117/mkl/lib/intel64/" --with-blas-libs="-L/opt/intel/composer_xe_2013.1.117/mkl/lib/intel64 -lmkl_blas95_lp64 -lmkl_core -lmkl_intel_lp64 -lmkl_sequential" --with-lapack-libs="-L/opt/intel/composer_xe_2013.1.117/mkl/lib/intel64 -lmkl_lapack95_lp64 -lmkl_core -lmkl_intel_lp64 -lmkl_sequential" --with-blacs-libs="-lblacs


After executing the command make yambo, I have the following error:

>>>[Linking yambo]<<<
make[1]: Entering directory '/home/fabiof/bin/yambo-4.2.1/driver'
cd /home/fabiof/bin/yambo-4.2.1/driver; /home/fabiof/bin/yambo-4.2.1/sbin/moduledep.sh yambo_driver.o > /home/fabiof/bin/yambo-4.2.1/driver/make.dep

I have tried the commands make clean or make clean_all, and I still get the error. I don't know what to do.
Do you have any suggestions?

The config file is attached.


Thank you,
Fabio

Dear Fabio,
please note that the option --enable-openmpi it is not correct, it should be --enable-openmp if you want to activate the OPENMP parallelism.
Next, I suggest you define in the configure line the compilers you want to use, in particular, you are using gnu for precompiler and intel for Fortran/C compilers, and this
could cause problems, you can add the following lines to the configure: CPP='icc -E' CC='icc' FC='ifort' F77='ifort' MPICC='mpicc' MPIFC='mpiifort'
Finally, check if your mpi libraries are installed correctly, do other compiled software works well in MPI?

Best,
Daniele

[Fabiof]

Dear Daniele.

Adding the flags CPP='icc -E' CC='icc' MPICC='mpiicc' F77='ifort' FC='mpiifort' to the ./config command solved the problem.

Thank you!

Fabio

Dear Daniele,

I am trying to run yambo in parallel mode, but it runs on serial mode.

My command is

/usr/local/openmpi/bin/mpirun -np 24  yambo   -F yambo.in -J PPA

The Yambo file:

Is this a problem of using mpirun from openmpi to run the jobs? I used another mpi (mpiifort) to compile yambo?
I attached the config.log

Thank you,

Fabio

[Daniele Varsano]

Dear Fabio,
from the conifg.log I cannot see anything wrong, can you upload the ./config/report file?
In what kind of machine are you running? There is a batch system? in this case can you provide the launch script?
Please post also the report and log files.

Nothing to do with your problem but note that in your input SE_CPU is not consistent with 24 cpus.


Daniele

[Fabiof]

The machine is a regular computer (not a cluster or anything like that) with the distro Linux Mint 18.1.
It has the intel 2017 installed on it.

I tried this batch file.

Code: Select all

#! /bin/sh

MPIRUN=/usr/local/openmpi/bin/mpirun
QE=/home/fabiof/bin/espresso-5.4.0/bin
YAMBO=/home/fabiof/bin/yambo-4.2.1/bin

for i in  5

do

sed 's/yy/'$i'/g' PPA.in > yambo.in

$MPIRUN -np 24  $YAMBO/yambo   -F yambo.in -J PPAW$i

done

The yy is the energy of the NGsBlkXp.

The report file is attached (I renamed it to report.log).

[Daniele Varsano]

Ok the code seems to be correctly compiled in parallel.
Can you provide a report and a log file of your calculation?

Does qe or any other code works in parallel? The "regular" computer has 24 cores?

Daniele

[Fabiof]

Yes, it worked with qe and the regular computer has more than 24 cores.
I called it regular because it is just a desktop computer with many cores and a significant memory ram.


I tried to do the calculation with 16 processor. But I still have the same problem.
I attached one of the log and report files. They are not complete.

[Daniele Varsano]

Dear Fabio,
yambo seems compiled correctly as you can see from the header:

GPL Version 4.2.1 Revision 110. (Based on r.14778 h.7b4dc3c)
MPI Build

the problem it looks to come from the mpi wrapper.
According to this link (openMPI with intel):
https://software.intel.com/en-us/articl ... -compilers

possibly you need to recompile yambo with mpif90 wrapper instead of mpiifort so substituting MPIFC='mpif90' instead of mpiifort.
Remember to do a make clean_all before recompiling.

Best,
Daniele

[Fabiof]

Dear Daniele,

With the flags

Code: Select all

MPIFC='mpif90' CPP='icc -E' CC='icc' MPICC='mpiicc'  F77='ifort' FC='mpiifort'

I get the error

configure: error: in `/home/fabiof/bin/yambo-4.2.1':
configure: error: linking to Fortran libraries from C fails

If I change FC to mpif90 i get the error

checking if FC precompiler works on FC source... no
configure: error: Found FC precompiler problems in processing FC source.
