尝试使用compute-sanitizer时无法找到注入库libsanitizer-collection.so

Question

compute-sanitizer --tool memcheck my_cuda_program

就是我正在努力做的事情。 我正在尝试这个，因为我得到了

Thread 1 my_cuda_program received signal CUDA_EXCEPTION_5, Warp Out-of-range Address.

当我通过 cuda-gdb 运行我的程序时。

但是，我明白了

========= COMPUTE-SANITIZER
========= Unable to find injection library libsanitizer-collection.so

将此作为输出。但是，libsanitizer-collection.so 存在于我的 /usr/lib/nvidia-cuda-toolkit 中。

我的 nvcc 版本是 12.4，这就是我使用compute sanitizer 的原因。 我使用 cmake 编译我的程序，如下所示

cmake_minimum_required(VERSION 3.29.2)
project(nnbody VERSION 0.1.0 LANGUAGES CUDA CXX)

include(CTest)
enable_testing()

add_subdirectory(third-party/yaml-cpp) 

enable_language(CUDA)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++20")

set(CMAKE_CUDA_STANDARD 20)
set(CMAKE_CUDA_STANDARD_REQUIRED ON)
# set(CMAKE_CUDA_FLAGS "${CMAKE_CUDA_FLAGS} -arch=sm_60")

# check openmp
find_package(OpenMP REQUIRED)
if (OPENMP_FOUND)
  set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
  set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
  set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
else ()
  message (FATAL_ERROR "The compiler does not support OpenMP.")
endif()

# check BLAS and LAPACK
find_package(BLAS REQUIRED)
find_package(LAPACK REQUIRED)
find_package(FFTW3 REQUIRED)

set(VTK_DIR "/usr/local/include/vtk-9.3/")
find_package(VTK REQUIRED)

file(GLOB ALL_FILES_SRC
     "src/*.cuh"
     "src/*.cu"
     "src/*.h"
     "src/*.hpp"
     "src/*.c"
     "src/*.cpp"
)

set_source_files_properties(ALL_FILES_SRC LANGUAGE CUDA)

add_executable(nnbody ${ALL_FILES_SRC})
target_link_libraries(nnbody PRIVATE ${BLAS_LIBRARIES} ${LAPACK_LIBRARIES} ${FFTW3_LIBRARIES} ${VTK_LIBRARIES} yaml-cpp)
set_property(TARGET nnbody PROPERTY CUDA_ARCHITECTURES 60 86)


set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)

我不知道该尝试什么..

Answer 1

我有同样的错误，

/usr/bin/compute-sanitizer

会尝试从

libsanitizer-collection.so

加载

/usr/bin

，但它位于

/usr/lib/nvidia-cuda-toolkit/compute-sanitizer/libsanitizer-collection.so

。 （*buntu 22.04、NVIDIA 驱动程序版本 550、CUDA 12.4）

您可以通过使用

strace

来确认

compute-sanitizer

尝试在哪里找到该库：

$ strace compute-sanitizer ./main 2>&1 | grep libsanitizer-collection.so
stat("/usr/bin/libsanitizer-collection.so", 0x7ffe926f6c20) = -1 ENOENT (No such file or directory)
write(1, "========= Unable to find injecti"..., 70========= Unable to find injection library libsanitizer-collection.so

可以使用

libsanitizer-collection.so

命令确定

locate

的实际位置：

$ locate libsanitizer-collection.so
/usr/lib/nvidia-cuda-toolkit/compute-sanitizer/libsanitizer-collection.so

我通过将

compute-sanitizer

移动到

/usr/lib/nvidia-cuda-toolkit/compute-sanitizer

目录并将其链接回

/usr/bin

解决了这个问题。

sudo mv /usr/bin/compute-sanitizer /usr/lib/nvidia-cuda-toolkit/compute-sanitizer/compute-sanitizer
sudo ln -s /usr/lib/nvidia-cuda-toolkit/compute-sanitizer/compute-sanitizer /usr/bin/compute-sanitizer

然后我收到一个新错误，但这可能无关：

========= COMPUTE-SANITIZER
========= Target application terminated before first instrumented API call
========= Error: couldn't find exit code.
