HIP + MPI Compilation Question

Open denisbertini opened this issue 3 years ago • 2 comments

Hi Trying to build with CMake 3.20.5 i got the following problem:

Singularity> cmake -S . -B build -DWarpX_DIMS=2 -DWarpX_COMPUTE=HIP -DAMReX_GPU_BACKEND=HIP -DCMAKE_CXX_COMPILER=hipcc -DAMReX_AMD_ARCH="gfx908" -DMPI_C_COMPILER=mpicc -DMPI_CXX_COMPILER=mpicxx -DCMAKE_PREFIX_PATH=/usr/lib/x86_64-linux-gnu/openmpi -DCMAKE_INSTALL_PREFIX=../warpx_install ../warpx_src

Any idea why the MPI_CXX compiler is claimed to be not found ?

Hi @denisbertini,

Thanks for reaching out.

Any idea why the MPI_CXX compiler is claimed to be not found ?

This error means you do not have MPI installed or fully configured. Your output above has a few more lines, which hint to a CMakeError.log file that would describe why the compiler does not work. My guess it's the current configuration options and compiler settings that you pass that cause a mini-MPI example compilation to fail during configure.

You can either:

  • run without MPI on a single node: pass -DWarpX_MPI=OFF to the CMake configuration line for this

or you provide and hint the location of MPI on the machine. For the latter case, can you please share details on the machine? Is this a desktop (in that case you don't need MPI) or an HPC system? Which HPC system:

  • system name
  • operating system and
  • modules loaded?

On which instructions did you base your current CMake line? Because we compile in a simpler way on HIP systems with regards to compilers and MPI hints and usually don't need to use the hipcc compiler wrapper:

  • Cray Example: https://warpx.readthedocs.io/en/latest/install/hpc/crusher.html
  • Ubuntu Example: https://github.com/ECP-WarpX/WarpX/blob/ee1548f32e406512076825daded6057d279abd4d/.github/workflows/hip.yml#L41-L59

@ax3l I am building on HPC on an environment very similar than SPOCK. We use singularity containers to build which contain all the dependencies to build warpx including MPI and ROCm4.3. In fact i use this container to run simulation based on PiconGPU code. I used the following warpx.profile:

#
# Environment #################################################################
#

# Compilers
export CC=/opt/rocm/llvm/bin/clang
export CXX=/opt/rocm/llvm/bin/clang++

export OMPI_MCA_io=^ompio
export OMPI_MCA_mpi_leave_pinned=0

export AMRex_AMD_ARCH=gfx908

trying to build gives me such errors:

MPI is not found at all during the build, but MPI is installed as system library within my singularity container. Any idea what could go wrong here?
