R: [deal.II] Re: Compilation deal.II 9.5

[Giuseppe Orlando]

Yes, I’m inside a clean directory. The output of mpicxx is “/opt/cray/pe/craype/2.7.10/bin/CC”, which is the same that I used to install all the other versions. The cmake version is 3.17.0.   Best   Giuseppe Orlando   Da: Bruno Turcksin Inviato: giovedì 20 luglio 2023 17:47 A: dealii@googlegroups.com Oggetto: Re: [deal.II] Re: Compilation deal.II 9.5   A few questions: are you configuring inside a clean directory? What's the output of mpicxx? Which version of cmake are you using?   Le jeu. 20 juil. 2023 à 11:11, giuseppe orlando <giusor...@gmail.com> a écrit : I agree. I had tried to set -DMPI_CXX_COMPILER flag, but it seems to be ineffective. It keeps using nvcc_wrapper for MPI.   Best Il giorno giovedì 20 luglio 2023 alle 16:41:09 UTC+2 bruno.t...@gmail.com ha scritto: What's strange is that when deal.II tries to compile an MPI code, it is using `nvcc_wrapper` as the compiler instead of `mpicxx`. Can you try to set `-DMPI_CXX_COMPILER=mpicxx`?   Bruno   Le jeu. 20 juil. 2023 à 10:21, giuseppe orlando <giu...@gmail.com> a écrit : Here, you can find both 'CMakeError.log' and 'CMakeOutput.log' Best,   Giuseppe   Il giorno giovedì 20 luglio 2023 alle 14:32:34 UTC+2 bruno.t...@gmail.com ha scritto: Giuseppe,   CMake should create an error log. Can you post it?   Best,   Bruno   Le jeu. 20 juil. 2023 à 04:51, giuseppe orlando <gius...@gmail.com> a écrit : Dear Bruno, I tried to reinstall Kokkos removing the -DCMAKE_CXX_FLAGS option, but I get the same error during the creation of the Makefile for deal.II. I will try to figure out which might be the problem in the follwing days.   Best,   Giuseppe  Il giorno mercoledì 19 luglio 2023 alle 19:36:53 UTC+2 bruno.t...@gmail.com ha scritto: Giuseppe,   I think the issue is because you set -DCMAKE_CXX_FLAGS=-arch=sm_60 when compiling Kokkos. This is not necessary because Kokkos takes care of that when you use -DKokkos_ARCH_PASCAL60=ON. Since you set that as a CXX flags it might be passed to MPI when it shouldn't. The rest looks good.   Best,   Bruno     Le mer. 19 juil. 2023 à 13:29, giuseppe orlando <gius...@gmail.com> a écrit : Dear Bruno, thanks for the suggestion. I tried to follow it, but I still the get same error during the creation of the Makefile. Just to sum up I typed "export OMPI_CXX=/project/sm77/bin/kokkos/bin/nvcc_wrapper" "cmake -DCMAKE_INSTALL_PREFIX=/project/sm77/bin/dealII/9.5.1/ -DCMAKE_CXX_COMPILER=/project/sm77/bin/kokkos/bin/nvcc_wrapper -DDEAL_II_WITH_P4EST=ON -DP4EST_DIR=/project/sm77/bin/p4est/ -DDEAL_II_WITH_MPI=ON -DDEAL_II_WITH_CUDA=ON -DDEAL_II_MPI_WITH_DEVICE_SUPPORT=ON -DKOKKOS_DIR=/project/sm77/bin/kokkos ../."   At this point, I'm wondering if the problem could be related to how I installed Kokkos. This is the command to generate the Makefile for Kokkos and the installation went good, but at this point, I really don't know.    "cmake -DCMAKE_CXX_COMPILER=/project/sm77/kokkos/bin/nvcc_wrapper -DCMAKE_INSTALL_PREFIX=/project/sm77/bin/kokkos -DCMAKE_CXX_FLAGS=-arch=sm_60 -DKokkos_ENABLE_CUDA_LAMBDA=ON -DKokkos_ENABLE_CUDA=ON -DKokkos_ARCH_PASCAL60=ON ../."    Best,   Giuseppe Il giorno mercoledì 19 luglio 2023 alle 15:09:28 UTC+2 bruno.t...@gmail.com ha scritto: Giuseppe,   Your configuration line looks good. I use the same but I also export OMPI_CXX=/path/kokkos/bin/nvcc_wrapper   Best,   Bruno   On Wednesday, July 19, 2023 at 4:38:07 AM UTC-4 gius...@gmail.com wrote: Hello everyone, I'm writing this post because I'm having some issues to compile the latest release. I would need a version which supports CUDA and MPI being CUDA-aware. Hence, I installed Kokkos using the flags -DKokkos_ENABLE_CUDA=ON and -DKokkos_ENABLE_CUDA_LAMBDA=ON. Then, I tried to build the Makefile specifying as CXX compiler the 'nvcc_wrapper' in Kokkos, namely using -DCMAKE_CXX_COMPILER=/path/kokkos/bin/nvcc_wrapper and using the flags -DDEAL_II_WITH_MPI=ON, -DDEAL_II_WITH_CUDA=ON, -DDEAL_II_MPI_WITH_DEVICE_SUPPORT=ON, -DKOKKOS_DIR=${Kokkos_dir}, but I get an error in finding MPI     I also tried to specify the compiler I have always used with the previous version via -DMPI_CXX_COMPILER flag, but I get the same error. Did someone encounter the same issue? Am I supposed to use 'nvcc_wrapper' also for MPI?   Thanks in advance.   Best,   Giuseppe -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to a topic in the Google Groups "deal.II User Group" group.
