+# gpu_load_smi
+
+Displays information about the current state of a specific NVIDIA GPU using the `nvidia-smi` utility.
+
+Although it will likely be zero, you should still confirm the GPU index.
+The GPU index can be fetched by using the `nvidia-smi dmon` command.
+`$ nvidia-smi dmon`
+```
+# gpu    pwr  gtemp  mtemp     sm    mem    enc    dec    jpg    ofa   mclk   pclk
+# Idx      W      C      C      %      %      %      %      %      %    MHz    MHz
+    0      3     51      -      0      0      0      0      0      0    405    210
+```
+The GPU index is the first column in the output. as depicted by the headers.
+Identify which GPU index you want and use that as the `GPU_IDX` parameter.
