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

[Bobnova]

Sadly no, http://curl.haxx.se/download.html
Then follow the directions in the README.

[mizerydearia]

Why in the makefile is there still

Code:

all: bitcoin

and

Code:

bitcoin: $(OBJS) obj/init.o obj/ui.o obj/uibase.o
        $(CXX) $(CXXFLAGS) -o $@ $^ $(WXLIBS) $(LIBS)

also, compile issues: http://privatepaste.com/c9f75d6086

[Bobnova]

Largely because nobody does a good enough job with search-replace when they release an alt coin.
Actually there is the possible exception of solidcoin, I don't remember bitcoin being in that one.  It may have been blanked from my mind by the fail though.

I guess Linux doesn't like me... Happens every time... That's why I still use Windows, at least things make sense to me there...
I'll give it another try tomorrow... Getting square eyes...

and partially ixcoin

Ahh, you'll need to install libcurl then.  After that, there will be libcurl.so at that path.

sudo apt-get install libcurl?

Yup, on a recent debian/ubuntu just installing one of the libcurl4-*-dev packages should be enough.

[Bobnova]

Knowing that would have made my life easier!  lol

[mizerydearia]

Any suggestions?

You're trying to build the gui client, for the daemon... make bitcoind
and the bitcoin wx gui always needed wx 2.9 ...

heh, right!  I completely forgot to specify bitcoin (or in this case bitcoind)

Perhaps the makefile for the daemon can default to bitcoind instead of bitcoin?  And maybe change them to tenebrix and tenebrixd?

[Lolcust]

I already did it for the pool version because some dude from Alaska pecked me oh so hard and oh so systematically over it expect all other branches/gits to get updated soon

[mizerydearia]

Code:

tenebrix@bitcoindearia ~/bin $ ./tenebrix
bitcoin server starting
Segmentation fault
tenebrix@bitcoindearia ~/bin $ [xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
tenebrix: /var/tmp/portage/x11-libs/libX11-1.4.4/work/libX11-1.4.4/src/xcb_io.c:273: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

Otherwise daemon works nicely.

[Lolcust]

tenebrix, not tenebrixd ?

Hm... I must be slow today... will look into it tomorrow....

[mizerydearia]

tenebrix miner

Code:

--url URL
URL for bitcoin JSON-RPC server (default: http://127.0.0.1:8332/)

Maybe it should be 7777?

Code:

Ah https://bitcointalk.org/index.php?topic=45667.msg545449#msg545449

Instead of 7777 must be 8697

[mizerydearia]

Where can I learn more about tenebrix difficulty?  I see it is currently 0.19238390

I stopped searching for 'difficulty' at end of page 15

[Bobnova]

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 somebody please make a service where we can see live difficulty etc. !?

Hash rate is crazy right now, we're hitting 4.2gh/s or the equivalent of about 350 AMD quad core processors.

Percent increase for difficulty is correspondingly going up about 10% a day, although it isn't exploded as rapidly as it was two days ago.

[MaGNeT]

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...

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