Dear Kefan,
here's my guess:
1. most definitely you don't need "sudo" to configure (nor to compile),
2. the configure script is detecting you system-wide installation of
OpenMPI that wraps gfortran instead of pgf90 and, as a consequence,
gfortran is used in all subsequent steps.
You have two options:
1. try a serial build, that makes sense since you have only one GPU on
your system. The configure command should look like this:
./configure F90=pgf90 FC=pgf90 --disable-parallel --with-cuda=$CUDA_HOME
--with-cuda-runtime=10.2 --with-cuda-cc=75 --enable-openmp
2. use openmpi provided by PGI, which is located here
/opt/pgi/linux86-64/19.10/mpi/openmpi-3.1.3/
(you need to add all relevant paths to PATH and LD_LIBRARY_PATH)
This will allow you to oversubscribe the GPU, but don't abuse this
possibility.
If you still have problems, please attach the full output of the
configure command.
Hope this helps,
best,
Pietro

Hi there,
I'm trying to compile QE-GPU 6.5a1 on my system but I failed with the
first step: run 'configure' executable. I followed the instructions
here:https://gitlab.com/QEF/q-e-gpu/-/wikis/home
<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.com%2FQEF%2Fq-e-gpu%2F-%2Fwikis%2Fhome&data=02%7C01%7Cpietro.bonfa%40unipr.it%7C86e6c1fe10a14ebe49a708d7ae89f109%7Cbb064bc5b7a841ecbabed7beb3faeb1c%7C0%7C0%7C637169780270039551&sdata=wuQe9BjdEBuOrERCUOSLxAhDOAVTbQXxsEE7W9CjOjg%3D&reserved=0>
The error Info I have, the full info of running 'configure' can be seen
at the end of the email:
checking whether Fortran compiler accepts -Mcuda... no
configure: error: You do not have the cudafor module. Are you using a
PGI compiler?
The command line I used to run 'configure':
sudo ./configure --with-cuda=$CUDA_HOME --with-cuda-runtime=10.2
--with-cuda-cc=75 --enable-openmp
CUDA toolkit was installed previously and individually, which is
functional since I compiled LAMMPS with that. I have an RTX2080 Ti GPU,
whose architecture is Turing, so cuda-cc=75. I also tried to change
$CUDA_HOME to /usr/bin/cuda(where I installed cuda) but the error
persists.My OpenMPI was also installed separately, and the version is 4.0.2
I installed PGI 19.10 under /opt/pgi so I modified my
environment variable with following command lines.
export LD_LIBRARY_PATH=/opt/pgi/linux86-64/19.10/include:$LD_LIBRARY_PATH
export PATH=/opt/pgi/linux86-64/19.1/bin:$PATH
export LM_LICENSE_FILE=$LM_LICENSE_FILE:/opt/pgi/license.dat
export MANPATH=$MANPATH:/opt/pgi/linux86-64/19.1/man
export CC=/opt/pgi/linux86-64/19.10/bin/pgcc
export CXX=/opt/pgi/linux86-64/19.10/bin/pgc++
export F90=/opt/pgi/linux86-64/19.10/bin/pgfortran
export F77=/opt/pgi/linux86-64/19.10/bin/pgfortran
export FC=/opt/pgi/linux86-64/19.10/bin/pgfortran
export PGI=/opt/pgi
Do I miss any step? Thank you for your help!
BTW, I tried running configure only without any extra flags. It turned
out to be successful.
