new version v2.3 can't connect to p2pool using stratum

If using cgminer, then it will connect to, like stratum+ tcp://p2pool.org, successfully
but cpuminer v2.3 can only connect to p2pool.org, and unable to stratum+ tcp://p2pool.org, why is this?

Thank you in advance.

I can replicate this.

Code:

minerd -a scrypt -t1 -o http://p2pool.org:9327 -O Lc8TWMiKM7gRUrG8VB8pPNP1Yvt1SGZnoH:x --no-stratum

Version 2.3

This version adds support for the Stratum mining protocol. The miner now recognizes URLs starting with stratum+tcp://, and can also switch from getwork to Stratum if the mining server supports the X-Stratum extension. For those who still don't know, Stratum reduces network resources consumption (only needs one TCP connection), and allows a significant reduction of the stale rate.
The miner should now automatically set CPU affinity on FreeBSD as it already did on Linux.
No speed improvements over version 2.2.3.

The source code is, as always, available at GitHub. Source tarball and binaries are available at Sourceforge (I had to switch from GitHub because they've deprecated their Downloads Tab).
Thanks to Tachikoma, we now also have a static 64-bit binary for Mac OS X.

NB: Stratum support does not render the Stratum proxy useless. You should keep using the Stratum proxy when pool mining, unless you only have one miner.

very nice

Well, according this thread: https://bitcointalk.org/index.php?topic=196196.2780

I should expect something like this:

Intel Core i7 2600K: 320 KH/s [AVX version, 4.43 GHz]

or, in a worst scenario, AT LEAST 200kh\s on scrypt-jane, mining YAC, since the 3d talks about a 4.43GHz CPU, and I'm on a 3.40GHz, as u can see.

The cpuminer discussed in this thread does not support YAC mining.
You are probably referring to ali1234's fork, which is discussed here.

Hello, I'm expecting problems under linux debian squeeze.

I updated my gcc to 4.7.3, to been able to compile with AVX flags:

Code:

./configure CFLAGS="-O3 -march=corei7-avx"

My cpu:

Code:

processor : 7
vendor_id : GenuineIntel
cpu family : 6
model : 42
model name : Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

(x8)

Well, according this thread: https://bitcointalk.org/index.php?topic=196196.2780

I should expect something like this:

Intel Core i7 2600K: 320 KH/s [AVX version, 4.43 GHz]

or, in a worst scenario, AT LEAST 200kh\s on scrypt-jane, mining YAC, since the 3d talks about a 4.43GHz CPU, and I'm on a 3.40GHz, as u can see.

Well, when I run the miner (on every pool) with 8 threads, it starts with something like this:

Q: Is there any command-line option I can play with to make cpuminer mine faster?
A: No. (But you can lower the number of threads to make it go slower.)

I'm sorry but that made me laugh. Watching a movie and playing games make it go slower too. I found turning the computer off gives the best results. Although the performance suffers but the savings in energy is wonderful.

That reminded me of the barometer question. Cheesy

Seriously, what you say is true, but is outside the scope of the question, which specifically addressed command-line options.

No, there is not! I was just havin a bit of fun.

Is this for linux users or is this something I should or need to use or try on win7? CFLAGS = -g -O3

Those are compile-time flags.

To make it go faster you can increase the priority of minerd.exe in the taskmanager utility under processes. It's a bit more performance but not a lot.

Hi.

I have PC with 4 CPUs x 4 cores. I run minerd --threads 16, but each thread uses inly 25% of cpu. Then I run minerd --threads 4, each thread uses 100% of cpu. What is problem?

Press control + alt + del at the same time and then click then click start taskmanager

then you will see something like this

The number of windows you see under CPU Usage History is the number of cores you have.

1 thread per cpu core is what you should set it at.

eg this is a 2 core cpu so I would use --threads 2
if it had 4 windows then use --threads 4

Are you sure you really have 4 CPUs with each 4 cores?
It sounds like you have 1 CPU with 4 cores.

1. You're in the wrong thread.
2. Don't use Reaper. It's obsolete, buggy and unmaintained. Use cgminer or bfgminer instead.
