build oddity with gcc 4.7
by Dave Hansen
gcc 4.4 and 4.6 will compile numatop for me, but 4.7 fails at link time.
good versions: gcc version 4.4.7 (Ubuntu/Linaro 4.4.7-2ubuntu1)
gcc version 4.6.3 20120918 (prerelease) (Ubuntu/Linaro
4.6.3-10ubuntu1)
bad version: gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1)
I'm not quite sure who to blame it on, but anyone who tries to compile
it on Ubuntu will probably run in to this. To work around it, just do:

CPU utilization display
by Dave Hansen
I also noticed that the CPU utlization doesn't seem quite right. While
numatop claims my kernel compile is taking very little CPU:
> PID PROC RMA(K) LMA(K) RMA/LMA CPI *CPU%
> 44242 ld 0.9 18331.3 0.0 0.71 0.6
which doesn't seem to fit well with what 'top' is saying:
> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
> 44242 root 20 0 1111m 849m 1408 D 99 0.1 0:08.85 ld
I'm not quite sure how numatop is scaling its numbers, but this doesn't
look quite right. Here's vmstat at the same time:

The only oddity in this system is that there are a lot of _possible_
cpus (160), but many fewer online (only 8 or so at the time I did this).

Feature request - numatop-tui
by Staffan Tjernstrom
First of all thanks for a really cool and useful tool.
I'd like to throw in a request for a non-X based version (along the
lines of latencytop-tui) as our main usecase would be on systems that
we want to keep X away from if at all possible.
