Package: libopenmpi3 Version: 4.1.0-7 Severity: important Tags: patch upstream X-Debbugs-Cc: tamiko+deb...@kyomu.43-1.org
Dear Maintainer, Please consider applying the following upstream patch [1] for a memory leak issue in OpenMPI-4.1.0. In short, the memory allocator for MPI_Datatype in the UCX PML does not correctly free allocated resources. Under certain workloads this lead to a severe memory leak that renders the OpenMPI library unusable. Upstream bug report [2]. I am reporting this issue for 4.1.0-7 but the issue is also present in 4.1.0-8.
