I love htop. But I can't figure out a way to disable the CPU monitors. I use a machine with 768 cores which makes it kind of useless.

- mikewhy 10y agoOh that is a little awkward. You can configure it, but the configuration options appear below the CPU bars. So if there's already so many that your screen is filled, that's a bit moot. This stackoverflow has some pointers though: http://superuser.com/questions/806614/how-to-compress-or-hide-the-processors-at-top-of-htop-on-large-machines http://superuser.com/questions/806614/how-to-compress-or-hid...
- etiene 10y agowow, 768 cores is a lot of cores! you can try posting an issue here? https://github.com/hishamhm/htop https://github.com/hishamhm/htop
- wwwhizz 10y agoYou obviously need a bigger screen
- zeptomu 10y agoI don't have 768 machines, but considering one writes a hypothetical bug report, what would be the instructions to trigger or reproduce the bug?
- sand500 10y agoIf you don't mind me asking what kind of machine has 768 cores?
- btown 10y agoLikely a machine with a group of Xeon Phi coprocessors, each a PCI card containing 64 fully-capable x86 cores: https://www-ssl.intel.com/content/www/us/en/processors/xeon/xeon-phi-coprocessor-overview.html https://www-ssl.intel.com/content/www/us/en/processors/xeon/... The idea is that you can run embarrassingly parallel workflows without needing to recode for a GPU; just launch processes with appropriate affinities. NERSC has compute clusters with thousands of these beasts. They make astronomers very happy.
- torrent-of-ions 10y agoActually a NUMA system, an SGI UV: https://www.sgi.com/products/servers/uv/ https://www.sgi.com/products/servers/uv/
- torrent-of-ions 10y agoIt's a NUMA system, an SGI UV: https://www.sgi.com/products/servers/uv/ https://www.sgi.com/products/servers/uv/ It actually has 2048 cores and ~7TB of memory.
- foob 10y agoOpen `~/.config/htop/htoprc` and modify the line: left_meters=AllCPUs Memory Swap to be left_meters=CPU Memory Swap That will replace the default CPU monitor with a single meter for the average across all cores. After that, you'll be able to customize things the standard way by pressing F2 within htop.
- torrent-of-ions 10y agoExcellent, this worked!
- vacri 10y agoTry reducing your cores to 16, then you'll be able to see some processes in the list!
