I created a small replacement for the built-in DGX Dashboard because I wanted to be able to access it without having to tunnel a port, I wanted to see RAM usage without cache/buffers, and I wanted some additional stats (like temps and CPU usage). However when testing it after a reboot, I noticed a …

The DGX Dashboard takes info from /proc/meminfo

@aniculescu are you able to share which values are read and how they are used? I’m also reading from there, but your numbers don’t seem to match. For example, right now the built-in dashboard is showing 74.53 GB / 128 GB (which is 58.2%), and the output of cat /proc/meminfo | grep Mem is: MemTota…

Clearly there’s a bug in the Dashboard calculation.

Spark has UMA (Unified Memory Architecture) so /proc/meminfo is not that useful. This file has info of what the kernel knows about the main memory. @aniculescu is the dashboard widget readings from cudaMemGetInfo()?

This looks better, but still doesn’t seem correct. Here’s my output of free -h --si and free -h and you can see that the actual usage is 3.6GB/128GB or 3.3Gi/119Gi, but the dashboard is showing 3.3/128. It seems that it’s still mixing up the units (showing the used memory in Gibibytes but the total …

What is the RAM value shown on the DGX Dashboard? It doesn't seem to match `free`
