Package: libopenmpi-dev Version: 4.1.0-10 Severity: important Tags: newcomer
Dear Maintainer, I have initially reported the issue at OpenMPI GiHub here: https://github.com/open-mpi/ompi/issues/11466 But I can't reproduce it for the recent version 4.1.5 that I built from source. Also I can't reproduce it for the currently reported version 4.1.0 for Fedora So I believe that the issue is somehow related to Debian peculiarities. The essence of the issue: The following code: ``` #include <mpi.h> int main(int argc, char *argv[]) { void *buf; MPI_Win window; MPI_Init(&argc, &argv); MPI_Alloc_mem(16, MPI_INFO_NULL, &buf); MPI_Win_create(buf, 16, 1, MPI_INFO_NULL, MPI_COMM_WORLD, &window); MPI_Win_free(&window); MPI_Free_mem(buf); MPI_Finalize(); } ``` compiled as ``` gcc testwin2.c `pkg-config --cflags --libs ompi-c` -o testwin.x ``` and being launched as ``` mpiexec.openmpi -n 2 --mca osc_base_verbose 100 --mca pml_base_verbose 100 --mca btl_base_verbose 100 ./testwin.x ``` fails with error messages: ``` [localhost:43128] *** An error occurred in MPI_Win_create [localhost:43128] *** reported by process [2029780993,1] [localhost:43128] *** on communicator MPI_COMM_WORLD [localhost:43128] *** MPI_ERR_WIN: invalid window [localhost:43128] *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, [localhost:43128] *** and potentially your MPI job) ``` The same code works well on Fedora PC both with ucx and ob1 PML implementations with the same OpenMPI version 4.1.0 -- System Information: Debian Release: 11.6 APT prefers stable APT policy: (900, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-21-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libopenmpi-dev depends on: ii gfortran [gfortran-mod-15] 4:10.2.1-1 ii gfortran-10 [gfortran-mod-15] 10.2.1-6 ii libevent-dev 2.1.12-stable-1 ii libhwloc-dev 2.4.1+dfsg-1 ii libibverbs-dev 33.2-1 ii libjs-jquery 3.5.1+dfsg+~3.5.5-7 ii libjs-jquery-ui 1.12.1+dfsg-8+deb11u1 ii libopenmpi3 4.1.0-10 ii libpmix-dev 4.0.0-4.1 ii openmpi-bin 4.1.0-10 ii openmpi-common 4.1.0-10 ii zlib1g-dev 1:1.2.11.dfsg-2+deb11u2 Versions of packages libopenmpi-dev recommends: ii libcoarrays-openmpi-dev 2.9.2-3 Versions of packages libopenmpi-dev suggests: pn openmpi-doc <none>
