profile_cuda

The profile_cuda gadget profiles CUDA memory allocations in libcuda.so (Driver API). It traces the following CUDA Driver API functions:

• cuMemAlloc_v2 - Allocate device memory
• cuMemAllocHost_v2 - Allocate page-locked host memory
• cuMemAllocManaged - Allocate managed memory
• cuMemAllocPitch_v2 - Allocate pitched device memory

The gadget aggregates memory allocations by user stack trace, allowing you to identify which code paths are responsible for CUDA memory usage.
