It sure is fun to see the entire top half of htop being taken up by individual CPU bars, but this is another program whose assumptions have been overtaken by the current silicon: At some point it is not that helpful anymore and makes looking at the processes themselves harder.
Sadly the development of htop seems to have stalled, patches/PRs for that and many other issues remain unmerged and unanswered.
- dijit 7y agoyou can easily change the CPU bars to be quarter sized. If you press 'F2' and look at the available meters you should see half and quarter sizes.
- blattimwind 7y agoEven then -- https://gamozolabs.github.io/assets/afl_256thread.png https://gamozolabs.github.io/assets/afl_256thread.png Note that this CPU has 128 threads, so half of that picture. For my usual terminal size I might get 0-2 processes listed below that...
- irishcoffee 7y agoI’ve found htop becomes less useful after about an 8 core count. Is there a reason you’d run htop over top in a normal use case?
- penagwin 7y agoHtop is IMO better overall with more helpful coloring, filtering, etc.
- thinkmassive 7y agoYou can replace all of those with a single Avg bar.
- philsnow 7y agoAt this number of processors, it starts to make sense to plot min/median/mean/90%ile/99%ile/max instead of gauges for each cpu. I would love to have this kind of problem :) _edit_: or just all the deciles and 1%ile + 99%ile

- rbanffy 7y ago> It sure is fun to see the entire top half of htop being taken up by individual CPU bars, You should have seen it with the Xeon Phi - the Phi could do 4 threads per core and the big ones had 72 of them, for a mind-blowing 288 threads. It was, however, much less forgiving than either of these beasts - L2 cache was Atom-sized and cache misses were not cheap.
- rbanffy 7y agoIIRC, the SGI Origin 2800 could go up to 512 MIPS R14000 processors. It's one thread per socket but, with 512 sockets and a single memory image, it'd most likely end up crashing htop. ;-)
