Hey, I was using Nsight Systems, and found the number of calls
cuMemAlloc is not equal to
cuMemFree in Stats System View → CUDA API Summary, does it indicate that there was memory leakage? My program is suspicious of GPU memory leakage, can Nsight System verify it?
the command I used was
nsys profile --trace=openacc,cuda,nvtx,mpi --mpi-impl=openmpi --backtrace=dwarf --cuda-memory-usage=true srun -N 1 -n 1 executive.
the version of Nsight System is 2022.1.3
