I like it :) I've never been much of a hardware guy, so I didn't know anything about my CPU. I have a shell alias called `i` (for info) that runs `neofetch && duf`, and I added cpufetch to that command
- nxpnsv 6y ago
  Thanks, I didn't know about duf!

    My favourite in that class of tools is `ncdu`. In a few seconds you can navigate through the files in your system and see (+delete) the space wasters! https://en.wikipedia.org/wiki/Ncdu#/media/File:Ncdu_screenshot.png https://en.wikipedia.org/wiki/Ncdu#/media/File:Ncdu_screensh...

I just realised after years of learning about how cores work that the big.LITTLE design is actually two CPUs not two sets of cores. With a third X1 core CPU we would then have 3 CPUs in a phone ... wow ...
- justinjlynn 6y ago
  It's processors all the way down. There are probably tens to perhaps even hundreds of independent processors in a modern phone/computer system design. They're elements of essentially every chip in the device - especially if they provide complex/integrated functionality or communicate digitally with other chips.
  - Brian_K_White 6y ago
    Thank you for "processors all the way down"
  - bartvk 6y ago
    If someone would say "processor", I'd expect them to mean the CPU, meaning the Central Processor Unit. The rest, I'd call them ICs.
    - loeg 6y ago
      Your typical harddrive has a full ARM core in it. Sure, it's an IC, but it's also reasonable to call it a processor (co-processor?).
      - taneliv 6y ago
        Or three cores: http://spritesmods.com/?art=hddhack&page=3 http://spritesmods.com/?art=hddhack&page=3 (2013, I think). The author only considers one of them "microcontroller-ish", the other two are "quite powerful arm9-like".
  - tumblewit 6y ago
    So they are essentially a combination of chips rather than a combination of logical units. I always assumed these ‘chips’ are made of logical units like computer cpus 20 years ago with different logical units but that is not true. This is probably why the M1 is better than the microsoft’s ARM implementation because probably Apple is not going the processor route and instead more tightly integrating these logical units reducing latency. This is definitely more work but the it’s probably worth it when you control every bit of the pipeline which is not possible when the pipeline is made of several vendors with their SDKs like on snapdragon based windows laptop.

I haven't done an lscpu check in a long time... at some point apparently it started telling me whether I am vulnerable to a whole bunch of cpu issues. That's amazing.
- chasil 6y ago
  I'm on Oracle Linux. Newer kernels report this in /proc/cpuinfo, and also /sys/devices/system/cpu/vulnerabilities. When I run the UEK 5.4 kernel, I can see the following: $ grep 'model name' /proc/cpuinfo | uniq model name : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz $ grep bugs /proc/cpuinfo | uniq bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit $ dmesg | grep DMI: [ 0.000000] DMI: HP ProLiant DL380p Gen8, BIOS P70 05/24/2019 When I run the RedHat-Compatible 3.10 Kernel, it doesn't report the bugs. This is Oracle/RedHat 7.9 Maipo, and lscpu doesn't report the bugs under either kernel.
signa11 6y ago
lstopo (1) on linux machines is quite instructive. if you have not used it before.
- gnufx 6y ago
  Yes, in general, hwloc (from which lstopo comes) is the thing to use for anything to do with CPU/memory topology, e.g. pinning to logical cores rather than physical ones whose numbering can even change with BIOS updates.
- BeefWellington 6y ago
  Strangely on my system `lstopo` shows only 7 CPU cores (0-6), instead of 8.

ryankrage77 6y ago
Bizarrely, this works fine in WSL (only missing max frequency), but doesn't work on Ubuntu Server running on bare metal. It identifies the CPU as Intel, but that's it.
- loeg 6y ago
  WSL1 is essentially bare metal and can run the CPUID instruction directly. WSL2 would run the same instruction, but it would trap cpuid in HyperV; passing-through some information, and synthesize other pieces (or at least, that's what I've seen other hypervisors do). Maybe the CPU in your Ubuntu machine is new and unrecognized by the program? I don't have any better guess.
gnufx 6y ago
For the most detailed info about x86 CPUs (only) I run cpuid.

What's the purpose for calculating "peak performance" (yes, I've seen the disclaimer in the source code that it is inaccurate) Looking into example screenshots, Xeon Gold 6328 is 10TFLOP/s, while Epyc 7702p is 2 TFLOP/s Performance comparsion can only be the other way around :-)
