The new rocm support in UCX is a great idea, but it's interfering with CI testing. It emits a warning to stderr, e.g. petsc on arm64 https://ci.debian.net/packages/p/petsc/testing/arm64/77493324/ 138s Using PETSC_DIR=/usr/lib/petsc 138s run SNES testex19 142s make: [makefile:36: testex19] Error 1 (ignored) 142s Possible error running C/C++ src/snes/tutorials/ex19 with 1 MPI process 142s See https://petsc.org/release/faq/ 142s [1793850805.012662] [autopkgtest-incus-kttidn:9570:0] rocmmem.c:246 UCX WARN rocm hooks installed with one mechanism only (bistro: Unsupported operation, reloc: Success) 142s lid velocity = 0.0016, prandtl # = 1., grashof # = 1. 142s Number of SNES iterations = 2 autopkgtest treats content in stderr as a test fail (unless explicitly permitted), so this UCX warning is causing a lot of MPI client packages to fail debci. The situation is a bit confusing: the ucx changelog says the rocm support is activated only for amd64, so why is arm64 affected? Or is that amd64 restriction strictly only for ubuntu? amd64 itself is not emitting this warning e.g. https://ci.debian.net/packages/p/petsc/testing/amd64/77493121/ Can the package be reconfigured to stop emitting this warning, without requiring extra env variables and without ignoring stderr in debian/tests?
