Topic: [ANN] ccminer 2.3 - opensource - GPL (tpruvot) (Read 499997 times)

For anyone who's interested ccminer no longer compiles on Ubuntu-21.10 (Cuda 11, GCC 11).

Cuda 11 requires all lines referencing sm_30 or sm_35 be removed from Makefile.am.

GCC 11 requires a fix ported from cpuminer and applied to 2 files: sph/blake2s.c, equi/blake2/blake2bx.cpp
https://github.com/tpruvot/cpuminer-multi/commit/7411020cefb5809202dd0db346df947a4561db4b

Just checked with 1.7.4 - both x86 and x64 versions
same behaviour, telnet connects, on first jey pressed exits to prompt :S
I tried changing port to 4069. no change

Tried running as admin/normal - same

X17 IS FPGA MINABLE--

There are a couple posts, in sequence, on the ZergPool thread.  Here is the link:

  Link to ZergPool thread- https://bitcointalksearch.org/topic/m.52643630

FPGA mining is a real thumbscrew for GPU miners.  A short while ago, $50/day for a single FPGA on a few algos, but now just $1-3/day at best.  And, FPGAs cost 3X-5X as much as a GPU rig of 6 or more cards.

This miner is not updated anymore. I did a quick test of the x17 algo on my RTX 2060 SUPER. The latest ccminer 2.3 does around 9MHASH,The popular alexis 1.0.0 fork is doing around 12 MHASH My free opensource suprminer/SPMOD-GIT is doing 19MHASH. The private miner Enemy/T-rex & co is doing around 26MHASH.
But it all doesn't really matter because there is no profit in 26MHASH.

Is X17 FPGA/ASIC minable, or is there a faster Private GPU kernel out there that harvest all of the profit?

Thank you kindly !

Any idea how to compile it on Ubuntu 19.04?  Will the dev update source code for compatibility?

Thanks, I should have realized that. I'll make the change in cpuminer-opt.

Edit: phi2-lux now makes sense, it's just a workaround for phi2 with roots enabled for miners
that can't handle them dynamically.

The connection:
When mining SPDR ( coin without roots ) all ok
Then switch to LUX or GEX (coins with roots ) all ok roots are enabled in ccminer.
Then switch back to SPDR ( coin without roots) BIG trouble.
From this moment ccminer is still in enabled roots mode and cant produce valid shares anymore.

Therefore the "has roots" check needs to be performed on every received job and set to false by default.
I think that's the best approach?

Simple problem, simple fix but what's the connection to profit swicthing?

When Mining Phi2 there's a "bug" in the software.

the use_roots flag for LUX and GEX is now being triggered and activated whenever a job contains a root parameter.
However the flag will never go back to false after this.

When using profit switching this causes a serious problem.

Please move the initial ' int use_roots = 0; '
To inside the ' work_decode ' function, so it gets checked on new jobs, to provide compatibility with profit switching.

Sorry for off topic but I think many here have mined Boolberry BBR. I thought you may like to know BBR to Zano swap. And yes BBR will still be supported after the swap ends July 30th 2019.

Hi, i have the following error mining on AWS EC2 instances, perhaps you have any advice for me?

Hi. Will you add the SINOVATE in your pool and algo X25X.
Thanks.

this is perfect and thats what i am looking for. A few months ago i was using the time-limit command and found
my gpus stuck on one wallet or pool for hours because the pool went down and i didnt figure out why it didnt move
on after 300 seconds until now because the time-limit has to mine that pool for 300 seconds or it wont switch.

you can easily recreate the issue by putting in a bad address or password in the first one and try yourself. it wont
go to the next wallet or pool til it mines that pool x seconds.

Time-limit is the only one that exits, the others like max-diff, max-temp just wait at idle.

i just wondered if anyone seen this issue or possible bug. Ok so i set up 3 wallets to do a time limited rotate of the wallets and i set time up with a max dif.  Maybe i am doing
something wrong i have tried in both windows and in linux.

here is my attempt with just max diff

:loop
ccminer-x64.exe -a skein -o http://192.168.1.215:9333 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0
ccminer-x64.exe -a qubit -o http://192.168.1.215:14242 -u htc -p x -d 0 --cpu-priority=4 --max-dif=25.0
ccminer-x64.exe -a myr-gr -o http://192.1681.215:9335 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0
GOTO loop
pause

it wont move off the first one at all and thinking i would mix in time limit to see if it would wait 180 seconds and go to the next one every 3 min

:loop
ccminer-x64.exe -a skein -o http://192.168.1.215:9333 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0 --time-limit=180
ccminer-x64.exe -a qubit -o http://192.168.1.215:14242 -u htc -p x -d 0 --cpu-priority=4 --max-dif=25.0 --time-limit=180
ccminer-x64.exe -a myr-gr -o http://192.1681.215:9335 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0 --time-limit=180
GOTO loop
pause

it wont move cause the miner didnt mine 3 minutes is what i am seeing.
If i runn with the --time-limit=180 command behind each one only it rotates thru them then goes back to the top one no issue.

This is what I get when running ccminer, it recognizes my gpu and even gives a hashrate, however it also says there is no kernel image available for execution on the device. Should I be concerned? I've read posts elsewhere about similar issues, but none of these were detecting the gpu. The other posts mentioned setting the cuda architecture to the proper one, but I cannot seem to grasp how that is done. I'm running Ubuntu 18.04 and cuda 9.1 with a GeForce GT520.

Thanks for the input Ilya, official ccminer is available for download at http://ccminer.org/

And don’t forget that it was, is and will be opensource, thanks to Epsylon3 and other contributors.
