[ANNOUNCE] Tenebrix, a CPU-friendly, GPU-hostile cryptocurrency

[Bobnova]

Excellent!

It ends up where I aimed you if you download the source and compile it, I didn't know there were prebuilt packages for libcurl.  Would have made things easier!
Anyway, how's performance?

Hashrate on my 1055T (@3.2Ghz) = 3.37 khash/s (x6 cores) 

[3phase]

I finally got minerd compiled (ArtForz version)...

First I did an " sudo apt-get install libcurl4-openssl-dev" but I couldn't find the libcurl.so file.
After a search I found it was in /usr/lib

I changed both the @LIBCURL lines in makefile to /usr/lib/libcurl.so

Then I did "make"  and suddenly I had " minerd"  


Another noob question:

How do I make a " batch"  file so I don't have to enter all the commands for minerd, every time I want to run it?
In DOS / Windows I know all this shit but in Linux? Learning...

Code:

nano miner.sh

put the following lines in the file:

Code:

#! /bin/bash
cd {MINERDIRECTORY}
./minerd --url ..... --user ... --pass ... -s ... -t ...

save it and do a

Code:

chmod +x miner.sh

Then just run miner.sh every time you want to start it.

Thanks! Works for me

I used
./minerd --url pool.simplecoin.us --userpass username:password -t 6

Should I add -s X or is the default scantime of 5 good enough?

Now my Phenom II 1055T @ 3.5Ghz and 3.5 khash/s.
So every Ghz = 1 khash/s  
vCore is at 1.325Volt (load line calibration on) and temperature 48C at full load.

Please merge mine Tenebrix and SolidCoin 2 !!! This will prove me that you ( Tenebrix guys ) have no bad intentions. Thank you !!!

D'oh
You need source code to do that - yeah think about it next time.
... and since the hash function is different you also can't merge mine.

Damn it !!! Plans ... crushed

^Interestingly,I believe the Masterpool site owner the approached the Solidcoin developer but mentioned it doesn't seem plausible to pursue for some reason or the other.


On the other hand would still love an Intel proc. optimized variant of "Minerd",lol.

Same. Otherwise fuck Tenecrapix and I move to SC2 as that is best for Intel !!!

Hey so this is in a different thread too, but it definitely belongs here:


For SandyBridge CPUs (corei7 with four digit model numbers) running Linux of some sort.

1) git the package.
2) ./configure  (screw the flags)
3) gedit Makefile
4) find the line with "CFLAGS = " (there may be flags, there may not be)
5) Change that line to: "CFLAGS = -march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4 -mavx"  No quotes.
6) make clean
7) make
start the miner, see how it does!


Brought my performance from 2.6kh/s per core (running one thread per core) to 3.66-3.7kh/s per core.

Tested with 6 threads, +2 kh/s in total.
HT works now!
Just needed some hardcore flags, that's all.


If you have a first generation core i CPU, leave -mavx off the end (ain't no VX), if it won't compile or won't run start cutting the -msse4.x lines off, starting with 4.2, then 4.1, then 4, eventually it'll start working.
Don't forget to make clean then make, if you don't make clean you won't get a new minerd.


I'm going to see if I can make some prebaked windows binaries for various CPUs, I may not have time till monday sometime though, we'll see.



If this works for you, let me know!
If it doesn't, let me know!

 Can I do something to optimize it?!

 Thanks!!

Your cpu doesn't have the AVX instruction set, thus the core dump.  Try CFLAGS="-O3 -march=native -msse4.2", that should be good for about 2.8 khash/core.

There is an Intel optimized variant of minerd.
You compile with the right flags for Intel, just like I did for the AMD variant.

I've been mining at 600 khash/s (2 threads) for a few hours now, which seems to be about 15% of the power of the entire network. I find it very hard to believe that there are only six 3-year-old Macbooks mining the entire chain right now, and I haven't gotten the one block per 30 minutes that I should be. Any idea what's wrong?

[Lolcust]

Errr, TBX is being solomined by about 279 solo nodes and who knows how many folks @ pool right now.

Where is the "three macbooks" thing coming from ?

How many CPU's are you using for mining?

[Vitalik Buterin]

Where is the "three macbooks" thing coming from ?

I said 6 3-year-old macbooks. Referring to my 3-year-old macbook seeming to have 1/6 of the power.

How many CPU's are you using for mining?

Two.

Are you comparing BTC performance and TBX performance ?

Or do you claim that your old macbooks can do scrypt-PoW that well ?

I think something is wrong on your side.
No way you are getting 600khash from any CPU at this moment 

What miner are you using?

Hm, odd.

So far, your case appears unique.

What build procedure did you use and what is the OS ?
