The estimation was just a rough guess based on a little testing. The main source of error though is the offset tables, so you could just compute the estimate after computing the actual size of them, given we are no longer restricting the PTL based on memory usage.Pttn wrote: ↑12 Dec 2018, 14:15Rockhawk, how did you find the 128 MiB + 650 MiB*SieveWorkers terms for the memory estimation?
It seems to work good enough for big Sieves, but the estimation is imprecise for very low Prime Table Limits as it estimates ~800 MiB, while I am able to run rieMiner (from the Light Branch) without swapping in a Pentium III computer with only 384 MiB of RAM...
Any way to get a more precise estimation in these extreme cases? This might still be useful for people willing to play with rieMiner in a RaspBerry Pi for example (such thing will still find very easily blocks on TestNet, a Pentium III is needing less than or about 10 minutes)...
And what was the 6-tuple record 20 years ago :D ? I have some vintage computers, it is always interesting to see what they can do with the software of today.
It looks like 20 years ago the record was 172 digits, I got a 213 digit record in 2000 and a 290 digit one in 2001 (that one using a couple of friend's machines in addition to my own).
20-25% faster is not impossible - we're over that if you account for the increased speed due to higher sieve limits and I'm sure some increases in raw speed are still possible (although I'm out of ideas right now).Pttn wrote: ↑12 Dec 2018, 14:15Also, what do you think about the riePool's claim of a miner 20-25% faster than fastrie (closed source)?
Legit or simple false advertising? If this were true for equal settings, it would be even better than rieMiner now.
He even pretended to have written a GPU miner 4.5x faster. As an expert in this domain, do you think this possible?
The facts are still that this is the biggest Riecoin pool for now, not sure if it is because people are thinking that they are mining faster and earning more with this software.
I don't know what 4.5 times faster using a GPU miner means - if he simply means comparing 100% CPU, no GPU to 100% CPU plus 100% GPU with a beefy graphics card, that may be possible.
Did you ever get to the bottom of those crashes? My miner has been running in debug for 324 hours now with no issues.
Just to let you know, I'm likely to remain mostly out of contact until the second week of January.
