Monero's Proof of Work algorithm (RandomX) and related topics. Use #p2pool-log and #p2pool-mini for P2Pool discussions. Anti-spam active: PM hyc for voice.

  I suppose other pool software could use this rpc too, also for memory savings if they needed it

  the glory of opensource, if they want to implement it, its all there for them to do so :)

  was looking at that arduino coin that can be mined on nanos etc. Then realised you could just GPU mine it, but they move you onto an extreme difficulty net

  then I looked a bit deeper, and the dev's control everything, its more centralised than the earth's core.

  <pauliouk> "then I looked a bit deeper..." <- Nice

  yeah, the dev's could just turn around and say "Hey, you're mining too quick, thats against the rules, closing your account and seizing your coins"

  someone went bonkers on RandomX memory: github.com/GiverofMemory/RandomX#randomxb

  wow. we're totally repeating 2014

  that was pebllecoin, it took cryptonight and made the memory requirement like 8gigs or something

  sounds like a good way to waste a lot of perfectly good hardware. like chia :P

  inb4 people claim randomx has only lasted this long because of the global chip shortage
• 22:33
  pauliouk
  oh please, will take a lot more than readily available silicon to take out RandomX :P
• 22:34
  pauliouk
  Those Russian ARM boxes might be a nice way to mine, but it'll be years before we can get our hands on them

  Fun that the light mode is as much as the normal mode of RandomX
• 22:42
  DataHoarder
  These are small numbers, 1 TiB RAM or bust
• 22:45
  tevador
  Their whole premise is wrong, no GPUs on the market can mine RandomX profitably.
• 22:46
  pauliouk
  technically speaking, no tech on the market can mine RandomX profitably unless you get lucky as fek solo mining
• 22:47
  pauliouk
  ROI's are really long - especially with the chip shortage throwing the investment costs through the roof
• 22:47
  » pauliouk says that, while the Ryzen 5 3600 build next to him is about 8 months from ROI.
• 22:53
  tevador
  if you already have the hardware, you can mine profitably with a CPU
• 22:54
  tevador
  GPU mining RandomX makes no sense even with stolen electricity
• 22:56
  pauliouk
  true. I doubt you'd even be able to mine enough to cover the wear and tear of the GPU

  the reference to "AI type graphics cards" was particularly laughable, since AI workloads are optimized for 8 bit ints
• 23:05
  DataHoarder
  And small floats
• 23:06

  tbh some CPUs on EPYC line are getting close to GPU level performance while being a CPU on their own
• 23:06
  DataHoarder
  Insane L3, and also number of cores
• 23:07
  DataHoarder
  I remember the joke of “oh I can boot Linux on this 12 MiB cache” but what do we have now, half a GiB of L3 cachev
• 23:07
  pauliouk
  :P

  aaaah to have a shipping contained filled with pre-build server boards, loaded with DDR5 memory and MilanX chips...
• 23:08
  DataHoarder
  It is becoming similar sized to GPU memory, with complex NUMA designs, and all kinds of hardware accelerations
• 23:09
  DataHoarder
  So yeah just do raytracing might be about as quick :’)
• 23:10
  pauliouk
  will I finally be able to run games from this millennia? :D

  the on-chip caches certainly make coldboot easier. we used to have to write bootloaders that fit in 256 bytes of cache
