NVIDIA odds on overtaking Intel

(source)

Not sure if you saw the NVIDIA GTC 2022 Keynote already, but if you like CPU/GPUs and wanna know what's coming in the HPC (High-Performance Computing) world, then give it a look (you don't need to listen all the crap of the omniverse... just skip that if you don't understand), just to see what NVIDIA plans to launch next year on the market.

These CPUs are just the beginning of a new way computers will start changing. And if you recalled the era where co-processors existed (90's), then this might ring some bells. And in my view, NVIDIA is just teasing the "market" (while dominating)... planning on a much bigger picture when/if they plan to flood the market with Desktop CPUs.

Anyhow, the numbers are just crazy. GDDR5 and property links (NVLink) between chips, yes, but that might be how they could overtake the PCIe standard. Maybe PCIe+NVLink compatible thing? LOL Who knows...

Intel needs to step up... 🤷‍♂️

Some changes on my HIVE node 🙄

It has been quite hard to spend time on this lately but a few days ago I was able to dedicate some hours to it and the end result is live and faster.

I have decided to do another replay of the HIVE blockchain with a smaller shared_memory.bin file size (details below) and finally move my witness from NVMe to RAM. I am not sure why I don't remember being such a big difference from last time I tested it, but maybe I didn't have that much IO hitting the NVMe as I do now, hence the performance might have degraded.

Anyhow, I am happy with it. And if you want a second reason to do it, then think about your NVMe endurance, as running the shared_memory.bin file from it, degrades/wears it out way faster than you think.

(At this point, many of the ones reading this are like, "who the hell uses NVMe to replay the HIVE blockchain anyway..." LOL... me! 😁)

Below are some notes and details of what changed for the ones on the same ride as me:

Set my shared_memory.bin to 22GB (but actual usage is 20GB) - you can verify this either via the du command or df on the /dev/shm place if that's the only thing you have there. (The size depends also on the plugins you use)
If you take snapshots like me (time to time) using an NVMe to dump the /dev/shm/shared_memory.bin is a great option (takes seconds).
If you plan on doing a replay (on RAM), it pays off more to first have a not older than a month or two old blockchain file downloaded. Preferably a just from the day one.
I have taken less than 24 hours to replay it using an AMD (zen, 1st gen). (Downloading the chain via hived replay mode is a lot less efficient compared with downloading it from someone else that has it up to date, if you trust that person of course)
Replaying via NVMe still works, but it will take about a week (depending on how fast is your device). You can use it as an alternative if you don't have enough RAM and a good NVMe you don't care to screw/wear off. It's great for tests...
Be sure to have time synchronization enabled on the system where you are running hived. I had some problems not long ago and when I looked it was not enabled for some reason I forgot.

I have some experimentation to do with huge pages... not sure if anyone did any and if that was helpful or not. But from 2MB to 1GB might be worth it for the replay process at least. Might not be a huge advantage for a witness-only node, but maybe for the bigger history ones it might make a little difference. If I go through the trouble of playing with it, I will post about it.

Kernel wise, I don't know anything useful to play with yet... but if anyone has any ideas or suggestions that you suspect might be interesting to test (maybe at the network level), let me know. It's sort of the things I like to play with on daily stuff anyhow.

🖐️HIVE5's!

Have fun, good luck on all the gaming, learning, and when/if you are up to, teaching new things to newcomers, showing them how interesting is this place.
