Hi thanhphatvt,

the following helped for me:

i changed the “lib” in the Makefile in olb.1.7.r0/externals to this:

all: lib zlib tinyxml
.PHONY: zlib tinyxml

lib:
mkdir -p lib

zlib:
make -C zlib
cp zlib/build/libz.a lib/

clean_zlib:
make -C zlib clean

tinyxml:
make -C tinyxml
cp tinyxml/build/libtinyxml.a lib/

clean_tinyxml:
make -C tinyxml clean

clean: clean_zlib clean_tinyxml
rm -f lib/libz.a lib/libtinyxml.a

and than this is my final config.mk for olb.1.7r0:

CXX := nvcc -ccbin=mpicxx
CC := nvcc -ccbin=mpicc

CXXFLAGS := -O3
CXXFLAGS += -std=c++17

PARALLEL_MODE := MPI

PLATFORMS := CPU_SISD GPU_CUDA

CUDA_ARCH := 80

FLOATING_POINT_TYPE := float

USE_EMBEDDED_DEPENDENCIES := ON

Furthermore i got the problem on our HPC that OpenMPI is not working when just loading the module so here are my modules I am using for HPC in Dresden:

ml release/23.04 GCC/11.3.0 OpenMPI/4.1.4 CUDA/11.7 UCX-CUDA

I hope that this answer is helpful for you.

Dear Yuji,

I got the bugs under control and it runs on multiple GPUs, it was a problem with Dresden University of Technology’s HPC, the UCX CUDA needs to be loaded separately.
For my future colleagues using Dresden’s HPC, here is what needs to be set up:

You need to load the following packages:
ml release/23.04 GCC/11.3.0 OpenMPI/4.1.4 CUDA/11.7 UCX-CUDA

My configuration looks like this:
# Example of a build configuration for OpenLB 1.7 with CUDA and OpenMPI

CXX := nvcc -ccbin=mpicxx
CC := nvcc -ccbin=mpicc

CXXFLAGS := -O3
CXXFLAGS += -std=c++17

PARALLEL_MODE := MPI

#MPIFLAGS := -lmpi_cxx -lmpi

PLATFORMS := CPU_SISD GPU_CUDA

CUDA_ARCH := 70 #or 80 for Alpha

FLOATING_POINT_TYPE := Float

USE_EMBEDDED_DEPENDENCIES := ON

I forgot to mention that my MPI is built with Cuda.

mca:mpi:base:param:mpi_built_with_cuda_support:value:true

Hi Adiran,

I guess i managed to solve the problem on my own.
I had some problems with “nvcc fatal : Unknown option ‘-Wl,-rpath'” but just deleting the path und changing the MPIFLAGS to

MPIFLAGS := -L/software/rome/r23.10/OpenMPI/4.1.4-GCC-11.3.0/lib -L/software/rome/r23.10/hwloc/2.7.1-GCCcore-11.3.0/lib -L/software/rome/r23.10/libevent/2.1.12-GCCcore-11.3.0/lib -lmpi

solved the issue for now.

Thanks a lot

-Alex

Hi Adrian,

thank you for the quick reply.

Unforthunatly this solution is leeding to more problems:

Yes and thank you for your help!

[aseidler]

I managed to reproduce this error the CUDA_ARCH number was to high

[aseidler]

To the second question:
Yes it is running without compilation errors on only cpu and mpi.

Hey Adrian,

i checked my code in respect to the examples. But still I got this error where I am a bit clueless.

Hello Adrian,

Thank you for the quick reply.

Indeed the space in the CUDA_ARCH definition was the gist of the matter.
Still, my code isn’t running but the examples like venturi3d are now running on the GPU.

All the best,
Alex
