Question to missing hashrate #304

Closed benediktwetzel closed 3 years ago

benediktwetzel commented 3 years ago

Hi, this is a really nice work!

However, unfortunately, it seems that it does not generate hashes while my CPU is running at ~100%.

I have tried SHA256, SCRYPT and QUARK and use Docker to run it.

To run, for example, with QUARK I use the following command:

docker run -it --rm cpuminer-opt:latest -a quark -o stratum+tcp://quark.eu-west.nicehash.com:3345 -u 3AnW7M1E8rLFRNrrzjYah67vFy5XdSdgxz -p x -t 3

The periodic report displays the following: 

[2021-03-24 21:57:02] quark: quark.eu-west.nicehash.com:3345
                      Periodic report 1m23s 6m01s
                      Share rate 0.00/min 0.00/min
                      Hash rate 0.00h/s 0.00h/s (506.68kh/s)
                      Submitted 0 0
                      Accepted 0 0 -nan%
                      Hi/Lo share diff 0 / 9e+99

What I am doing wrong? Good day!

It's hashing quark at 506.68kh/s but that's not enough to find shares. The effective hash rate is zero because no shares were submitted. The pool will also report zero for the same reason.

You need an ASIC miner for these algos. Look at the share TTF in the New Block log, it should give you a clue whether your CPU can be expected to find shares on a regular basis. If share TTF is more than 5 minutes you are likely to have stratum disconnects also.

Stratum difficulty also affects share rate. Some pools automatically adjust stratum difficulty but there is a limit. For some algos even the lowest permitted difficulty isn't low enough for a CPU.

Thank you!
