无法为 CUDA NVlabs SASSI 工具构建示例
Unable to build example for CUDA NVlabs SASSI tool
我正在尝试构建和 运行 来自 NVlabs 项目 SASSI 的示例代码，可用于检测 CUDA 代码。但是，我什至努力让包含的示例 Makefile 和 matrixMul.cu 正确构建和 运行。
我尝试添加 --maxrregcount=16 和 -rcd=true nvcc 标志，但我认为我真正的问题是正确链接到 SASSI 库。下面 nvcc 输出中列出的所有库路径都解析为包含 .so 个文件的实际目录。
非常感谢任何提示或调试步骤。

* - It MUST BE compiled using only 16 registers!! To accomplish this
* simply compile your library with the nvcc flag, --maxrregcount=16
* - It must define the following functions:
* device void sassi_before_handler(SASSIBeforeParams*,SASSICondBranchParams*)

解决方案是安装 Boost，在 instlibs/env.mk 和 运行 make all 中设置适当的路径，然后再尝试构建示例代码。路径设置正确，但并未生成所有必需的 SASSI 库。
