Describe the bug

When GPU memory goes up to 1 G it shows it wrongly as 101M for a bit.. Once it gets higher i think I have seen it display 1G properly.. but it must be around the change-over from M to G.
This confused me a bit because i thought i was running light on memory, until i saw the startup sequence as shown in the video below and confirmed it with the graph on page 2(GPU)

To Reproduce

When starting a program that will take heaps of GPU memory it goes up to 900M then it suddenly shows 101M even though the memory has still gone up.

It shows it wrong in both the 1(All) screen next to the process as well in the 2(GPU) total GPU graph

See this example https://www.youtube.com/watch?v=R_rWsqLXMfw

Expected behavior

just showing either 1000 M or 1 G

Hi @clogwog (also reply for @artur-ag and @vesselofgod #469 )

I am aware of an issue where the output plotting in my jtop new version generates errors. I have worked to reduce the occurrence of this bug. The issue stems from the use of ASCII characters to plot the output, and there are cases where there is no small or big ASCII block available to perfectly plot the output.

I'm not sure if you have any experience with ASCII coding, but I was wondering if you could help me fix it. It would be really helpful for me! I wrote and updated this code some time ago, and the plot object is available at https://github.com/rbonghi/jetson_stats/blob/master/jtop/gui/lib/chart.py

From what I understand, the issue is that there's only space for 4 characters in most places of the UI, but all values between 1000M and 1023M take 5 characters, and are truncated to 101M. Values higher than 1024 get correctly converted to 1.0G. This is not an issue just with the ASCII plot, but also in the text output.

One way of fixing it would be to start using the higher unit whenever the value goes above 999, even if the value in the higher unit is not above 1 of the larger unit. Like this:

  • 999 MiB is rendered as 999M
  • 1000 MiB is converted to 1000/1024 = 0.9765 MiB, and rendered as 0.97M
  • 1023 MiB is converted to 1023/1024 = 0.9990234 MiB, and rendered as 0.99M
  • 1024 MiB is exactly 1 GiB, and rendered as 1.0G
    This guarantees that the value written in those 4 characters is always correct (even if a bit ugly).

@rbonghi I'm not familiar with the code, but from what I can tell, it's not chart.py making these conversions between units, but some other code before this, right? I see common.py has some unit conversion code. Maybe that's where this new behavior needs to be implemented (if you agree that this solution is adequate, that is).
