How to explain this figure about `nvidia-smi` with NVIDIA GPUs?

I have just run the simpleMultiGPU in a server with two K20m GPUs installed. And then run the nvidia-smi command to show the status of the GPUs. The result is as follows:

enter image description here

The problems are as follows:

  1. the GPU Memory Usage seems to be not the same.
  2. the Volatile GPU-Util of device 1 is 99%.

Any advice?

  1. There is no concept that says memory utilization must be the same when running apps on more than one GPU. Furthermore, memory utilization can vary at different points in the application, depending on the underlying activity (such as the point at which allocations are made) when the sampling of memory usage occurs.

  2. The Volatile GPU usage of device 1 probably indicates that the application and/or nvidia-smi is causing activity on device 1.

It's not clear why you refer to these as problems. You are monitoring activity on the device.
