Segmentation fault Yambo 5.2/5,3 [CPU]

Posted: Thu Apr 09, 2026 3:14 pm

Dear all,

I am trying to configure and compile Yambo 5.3 [and alos tried 5.2] on the CPU-cluster Fritz HPC [FAU, Erlangen].

(1) Compiler:
Intel Ice Lake Server


(2) Architecture:
Intel Ice Lake Server

(3) if the problems occur compiling in serial/in parallel
serial [probably also in paralle, but need to try, to be certain]

(4) the version of Yambo (revision number/major release version)
5.3 [downloaded the source code from the official git repo of Yambo and changed the branch 5.3 using git branch -a, git checkout 5.3]
5.2 [downloaded the source code from the official git repo of Yambo and changed the branch 5.2 using git branch -a, git checkout 5.2]

Further, I would like to share that the compilation was performed on the login node

Code: Select all

module purge
module load intel/2021.4.0
module load intelmpi/2021.6.0
module load mkl/2021.4.0
module load hdf5/1.10.7-impi-intel
module load netcdf-c/4.8.1
module load netcdf-fortran/4.5.3-intel


H5PFX=$(dirname $(dirname $(which h5pfc)))
NCPFX=$(nc-config --prefix)
NFFX=$(nf-config --prefix)

export CC=mpiicc
export FC=mpiifort
export CXX=mpiicpc
export PICC=mpiicc
export MPIFC=mpiifort
export MPICXX=mpiicpc

  --with-fft-libs="-L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl"

After the compilation, I dont get any error, but whil running the tddft calculation, I get the error:

Now, the strange part for me is that the TDDFT jobs are running perfectly nicely with Yambo 5.0 [also installed with the same commands]. So, I am bit perplexed about why its not working with Yambo 5.3 and 5.2


Can you help?

Dear Vipul,
please provide the report of your compilation (config/report), an input file and the log file of your tddft run

Meanwhile, few remarks.

If you are using tddft in transition space, in yambo 5.3 the implementation was completely rewritten to be much more efficient. However, it is still possible to switch to the older implementation by using the following input variable

Code: Select all

FxcMode="R-def"
yambo 5.2 and previous versions always use R-def implementation

Moreover, there was a bug in the R-def implementation, which was introduced in 5.2 and fixed only in 5.4. I just pushed the fix now in 5.3
Please try to re-compile 5.3 after git pull, and test tddft with both FxcMode="G-def" and FxcMode="R-def"
Alternatively you can directly switch to 5.4. If non of this options works, you can also check the lumen fork of the yambo code: https://gitlab.com/lumen-code/lumen

Last, please also remember to check on how many threads you are running.

Best,
D.

Dear Davide,

Thanks a lot for quick reply!

I did follow all the suggestions shared by you.

1. pulling 5.3 from the git and recompiling it and then running the input with both modes FxcMode="G-def" and FxcMode="R-def", however, I get the same error.
2. pulling 5.4 from the git and compilng it and running the input file with both modes FxcMode="G-def" and FxcMode="R-def", however, I get the same error

I also understand that it might be due to the memory issues, however, the same calculation with same threads and nodes run using Yambo 5.0. So, I think I am making some mistake either during the compilation or running the job. To give you further insight, please find the input file and log files for 5.3 and 5.4. Also, please find the compilation (config/report) for each compilation attached.

And yes, eventhough, the exact same calculations are going as desired using 5.0 branch, I am interested in using the newer versions, cause they have faster implementations and it puzzles me where I am going wrong. Would be great, if you can help me figure it out.

Ok, then I'm not sure about what is going on.

Can you also add the log of the succesfull run with 5.0, and the report (r-jobanme) of the three runs ?

Best,
D.

Ok, from the reports and the log, I'd say the reason is the different default parallelization, which in turn requires more memory

Please add to your input file

Code: Select all

X_CPU= "4.2.2.1.1"               # [PARALLEL] CPUs for each role
X_ROLEs= "g.v.c.k.q"             # [PARALLEL] CPUs roles (q,g,k,c,v)
X_nCPU_LinAlg_INV= 16            # [PARALLEL] CPUs for Linear Algebra (if -1 it is automatically set)

Note, you are running on 16 MPI tasks and 18 threads, for a total of 288 cores. Is this wanted?
I'd say this is not very efficient

To control the number of threads you can set

Code: Select all

export OMP_NUM_THREADS=1
(or any other number of threads you like, in your submission script.

Best,
D.

About the OMP_NUM_THREADS, yes first I tried with less OMP paralleziation, however, despite beiong slow, I had to go with higher values of OMP_NUM_THREASDS, just because otherwise it goes OOM very quickly.

However, now, I again I tried with OMP_NUM_THREADS =1, and I get the same error. Can you help me debug it?

Just to be sure. In the last log you both set the parallelization, and change the number of threads.

I'd first just change the parallelization, and then eventually the number of threads.

Best,
D.
