Okay, that makes sense.
Can you suggest any algorithm where CPU-mining still makes sense and that also works with cpuminer-opt?

Hello together!

First of all, thanks to JayDDee / joblo for your fork of cpuminer-multi, I think it's pretty cool (when I finally can make it run ;-))
I would like to use this piece of software to mine for Nicehash.com
I have just compiled the latest version of cpuminer-opt from Github on my Ubuntu server and ran the following start-command:

Quote
./cpuminer -a scrypt -o stratum+tcp://scrypt.eu-west.nicehash.com:3333 -u 3GoaYEXEYLJ8Kri6apdt6yZsvSvHdqDksc.testminer1 -p x

For me, it seems like the program is running properly, and I can also see the machine appeard in the menu of Nicehash, but always with "Accepted speed: 0.0000 MH/s".
When I run htop, I can see my CPUs are at 100%.

After some time, I get this report, which also confirms that "0" has been submitted / accepted.

Does anyone has an idea of what I'm doing wrong? I have also tried other algorithms, but with the same result...
Any help appreciated!
