Update memory statistics table

[victorapm]

What is the requested feature? Add minimum and average (across ranks) memory utilization statistics from umpire and update format of the statistics table.

Is your request related to a specific problem? No

Describe the solution you'd like Here is an example of what we currently have:

Umpire          DEVICE sum across ranks: 15293.4 GB
Umpire          DEVICE         rank max:   31.3 GB
Umpire       DEVICE::0 sum across ranks: 15293.4 G
Umpire       DEVICE::0         rank max:   31.3 GB
Umpire            HOST sum across ranks: 7272.2 GB
Umpire            HOST         rank max:   14.7 GB
Umpire HYPRE_DEVICE_POOL sum across ranks: 7178.4 GB
Umpire HYPRE_DEVICE_POOL         rank max:   14.8 GB
Umpire          PINNED sum across ranks:  256.3 GB
Umpire          PINNED         rank max:  589.6 MB

This is what I propose:

+-------------------+---------------+---------------+---------------+--------------+
|       Umpire Pool |    Min (GB/%) |    Max (GB/%) |    Avg (GB/%) |   Sum (TB/%) |
|                   |    over ranks |    over ranks |      per rank |    all ranks |
+-------------------+---------------+---------------+---------------+--------------+
|            DEVICE |   31.3  (49%) |   31.3  (49%) |   31.3  (49%) |  15.2  (24%) |
|              HOST |   14.7 (2.9%) |   14.7 (2.9%) |   14.7 (2.9%) |   7.2 (2.9%) |
| HYPRE_DEVICE_POOL |   14.8  (23%) |   14.8  (23%) |   14.8  (23%) |   7.1  (13%) |
|            PINNED |  0.589 (0.1%) |  0.589 (0.1%) |  0.589 (0.1%) |   0.3 (0.1%) |
+-------------------+---------------+---------------+---------------+--------------+

Describe alternatives you've considered N/A

Additional context Having access to minimum, maximum, and average utilization leads to a better understanding of load balancing.

Yes, this would definitely help.

We could also add the number of ranks in the output log to be able to trace that info more easily.

@MelReyCG you shouldn't put an issue in the ready status without filling the Impact / ... / component fields. Also, ready means that you're going to work on this soon. Is it what you meant when changing the status?

[MelReyCG]

I'm not sure what you're talking about, I don't think I did that myself, I just assigned myself to this issue because I will start working on it soon.

[TotoGaz]

Didn't you do ?

[MelReyCG]

Yes I did, we moved it. I just filled the fields.
