Hi, there,
My code runs with version 15.10.
After updated to version 16.1, my code frequently stopped with message like:
Out of memory allocating 13421760 bytes of device memory
total/free CUDA memory: 2147155968/13303808
Present table dump for device[1]: NVIDIA Tesla GPU 0, compute capability 2.1

call to cuMemAlloc returned error 2: Out of memory
At first I am thinking this is a problem with GPU memory not cleared after previous failure. Then I am thinking it could be related to GPU and CPU bindings, as I have 6 GPU cards, and running 12 MPI talks.
Appreciate your help,
Thanks,
Wei
