Hello, I am trying to sort out an odd crash on exit while using NVCC (via Kokkos-CUDA) and the Boost Unit Test Framework. Here my are data points: Kokkos-CUDA with the Boost test tool infrastructure - Crash Kokkos-HIP with the Boost test tool infrastructure - works Kokkos-Serial with the Boost test tool infrastructure - works Pure CUDA with the Boost test tool infrastructure - works Serial with the Boost test tool infrastructure - works Kokkos-CUDA alone (e.g. normal application) - works For the first case I have three scenarios (only used to high the Kokkos usage - the code does not crash in Kokkos::initialize), two of which crash: if(true) Kokkos::initialize(argc,argv); crash in CUDA - SEGFAULTif(false) Kokkos::initialize(argc,argv); crash in elsewhere - Subprocess aborted#if 0 Kokkos::initialize() #endif No crash For the first scenario the call stack is the following: #0 0x00001555521b5d9a in ?? () from ./cuda/12.2.0/lib64/libcudart.so.12 #1 0x00001555521b8c14 in ?? () from ./cuda/12.2.0/lib64/libcudart.so.12 #2 0x000015555219d882 in ?? () from ./cuda/12.2.0/lib64/libcudart.so.12 #3 0x00001555521a072b in ?? () from ./cuda/12.2.0/lib64/libcudart.so.12 #4 0x000015554b3b5797 in __cxa_finalize () from /lib64/libc.so.6 #5 0x0000155551301a87 in __do_global_dtors_aux () from build_kokkos_cuda/library/Operators/libOperators-g.so.5.5.0 #6 0x00007fffffffad10 in ?? () #7 0x000015555532dcee in _dl_fini () at dl-fini.c:141 For second, the call stack is quite deep after the call to __cxa_finalize () otherwise the first four (4-7) are the same. At this point the only culprit I can perhaps point at is nvcc I know at that previous versions of Boost and nvcc did not get along. And such, wondering if the usage is a corner case because I know of another project that is successfully using all three Boost, Kokkos, and CUDA. I am using Boost 1.85, Kokkos 4.3, and CUDA 12.2. Any insight or thoughts ? Our unit test work with Kokkos-HIP so able to validate results. Allen Sanderson SCI Institute University of Utah
