Uncoordinated-multi-process-GPU-usage.md

+* Description: When multiple processes use the same GPU in an uncoordinated way this can lead to a dramatic reduction of efficiency.
+* Criterion:
+  * nv_compute_processes>1
+  
+* Works for shared jobs with existing metrics:
+  * yes, if a GPU is allocated to at most one compute job
+  
+* Possible false positives:
+  * 
+
+* Possible cures/workarounds:
+  * check MPI-rank-GPU affinity/visibility
+  * deploy MPS (https://docs.nvidia.com/deploy/mps/index.html)
