Detecting undefined behaviors in cuda c
WebJun 24, 2024 · The solution was to enable CUDA_SEPARABLE_COMPILATION for all files with __device__ functions and only for files with __global__ functions also enabling CUDA_RESOLVE_DEVICE_SYMBOLS. Also adding dummy.cu files to the project helps CMake identifying CUDA code. Among many others, these two links helped me finding … WebThe 11.2 CUDA C++ compiler can optionally generate a function-inlining diagnostic report for device functions that can provide insights into the compiler’s function inlining decisions. These diagnostic reports can aid advanced CUDA developers in application performance analysis and tuning efforts.

Did you know?
WebUndefined behavior may also cause buffer overflow attack, if for example an array out of bounds is not checked. The advantage of undefined behavior in C is that the program avoids the unnecessary checking (such as arrays out of bounds), that results into better performance. C99 international standard presents a list of 191 undefined behavior cases. WebBus errors occur when you're trying to access an address which doesn't exist. Check in your code you've assigned pointers correctly, especially uses of the * and & unaries, since * can dereference a pointer variable. It'd be helpful to see your code and the gcc output with the -Warn and -Wextra flags. bananaskywalker • 4 yr. ago
WebThe run-time behavior can be influenced using the LSAN_OPTIONS environment variable. The option cannot be combined with -fsanitize=thread. -fsanitize=undefined. Enable UndefinedBehaviorSanitizer, a fast undefined behavior detector. Various computations are instrumented to detect undefined behavior at runtime. WebIt is developed to evaluate how current CUDA compilers deal with undefined behaviors. Then, we present the design and implementation of a system that can detect and locate …
