I am using Ubuntu 20.04 and recently installed CUDA Toolkit 11.0 Update1 without the included graphics driver (using latest proprietary driver from Software Updater). The issue is every 1-2 minutes, a cuda
process named systemmd
is started and uses ~4GB of GPU memory. In addition, my system experiences a significant slowdown. I can temporarily resolve the problem by killing the process, but it starts again in 1-2 minutes. I have experienced this issue on different machines and cannot figure out why this happens. I followed the official installation documentation, excluding the steps for Power9 systems. Here is what nvidia-smi
displays when this occurs and my current CUDA version–please let me know if more information is needed to diagnose the issue:
