High memory usage with SSE2, scryptn2 #351

Closed scorpim closed 2 years ago

scorpim commented 2 years ago

Tested scryptn2 with SSE2 and the memory usage is 3.17.1 - 790 MB - 5.1 H/s (The HDD goes nuts when closing the program) 3.19.1 - 515 MB - 3.5 H/s

When 3.19.1 starts up, you get this message: Scrypt paramaters: N= 1048576, R= 1 Throughput 4/thr, Buffer 256 MiB/thr, Total 0 iB There is no message like this with 3.17.1

Yes, it's the scrypt again. it's slower with 3.19.1 Is it possible if you could look into this slow scrypt too with SSE2? I dont want to buy a new PC :) I know you don't want to, but...

Testing platform Windows 10 GenuineIntel Pentium(R) Dual-Core CPU E5300 @ 2.60GHz MMX supported SSE supported SSE2 supported SSE3 supported SSSE3 supported

My Laptop has even SSE4.1. The memory usage is the same, but it's hashing faster then my PC, despite slower CPU 3.17.1 - 790 MB - 5.8 H/s

You can test this here --algo=scryptn2 --url=stratum+tcp://scryptn2.eu.mine.zpool.ca:4339 --user=YOURWALLET --pass=c=BTC,zap=XBTX Get payed in BTC Mine for XBTX

I wouldn't mined to test poolers minerd for memory usage, but I dont know what this is scrypt:N scrypt(N, 1, 1) Is it the same as --algo=scryptn2 ? It's an unknown algo What the hell is the code? Could you please help me out with this puzzle? If you look at this page https://zpool.ca/algo/scryptn2 "Miners Version", you'l see that nobody is using minerd... I wonder why :)...

The CPU is 15 years old and it only a pentium. I think it's time for a new one. I also explained my reasoning in your previous issue.

Yeah, you did... Could yo please at least explain how to use "scrypt:N scrypt(N, 1, 1)" I tried many combination but cant make it work. Your is so simple "sryptn2"

By the way. Where can I find some info how to use --api-remote ?
