[QE-users] information about PGI compiler v20+ download

Thu Oct 29 12:02:49 CET 2020

Hi Sitangshu,

Indeed the syntax is incorrect as Paolo said. You missed a “-L” in the LIBS

It should be:

./configure CC=pgcc F77=pgf90 FC=pgf90 F90=pgf90 MPIF90=mpif90 --with-cuda=/usr/local/cuda/bin --with-cuda-runtime=9.2 --with-cuda-cc=70 --enable-openmp LIBS=-L/usr/local/cuda/lib64/stubs/

Also consider trying this line as well (to use CUDA 11):

export CUDADIR=/apps/compilers/pgi/2020/Linux_x86_64/20.9/cuda/
./configure --with-cuda=$CUDADIR --with-cuda-runtime=11.0 --with-cuda-cc=70 --enable-openmp --with-scalapack=no LIBS="-L$CUDADIR/../math_libs/lib64 -L$CUDADIR/lib64/stubs/"

Dear Louis,

Thanks for your suggestion. I made the changes as you suggested, but some other compiling error in line 92 is constantly appearing.
I am attaching the config.log file for you to check please...

Regards,
Sitangshu

Hi Peirto, I tried to run the QE config file after installing the pgi compiler (20.9). It seems that pgifortran issue is now solved, but stuck with libcuda:
Please let me know...
Thanks,
Sitangshu

Thank you Peitro, but the link only tells about nvhpc. I couldn't get the pgi compilers there...

Dear all,

I am in search of a pgi compiler V20+ to run QE on a V100 GPU. I looked in the nvidia and pgi websites, but it seems some sort of tie up is needed between the guest and pgi organizations. As this may take some time, may I know if there are any quick download links...?
