[ANN] ccminer 2.3 - opensource - GPL (tpruvot)

[joblo]

strange, i can reproduce it with "-a blake", "-a blakecoin" beside "-a decred" (even with --benchmark)
blake2s, vanilla and other algos are fine
well, i'll stick with alexis78's ccminer for decred...

Are you waiting long enough for the cards to start? I've seen cards take up to 2 minutes before they report any hash.

no, didn't wait 2 minutes but even, with alexis78's miner all cards starts immediately...

Is there any stat for how lucky your pools has been for LBRY? It seems we have terrible luck finding blocks.

he will not sell you anything anymore, until 20 of this month, where it will be released

[Epsylon3]

yep, even if it was not enough to limit the 2x nethash and difficulty increase per day that should help a bit

ive also some other "finitions" to do.. for a final 1.8 release... no big/perf changes in the algo

yep, i powered on my last machines, didnt had the time to update/compile before but its only 3x 970 more :p damn rush, look like mining is more and more popular

but the pool works perfectly else, not a single block rejected... just miners not sending shares high enough

is gtx 760 optimized?
cause i have one and im getting only 19.75 hashrate, while banchmarks here http://yiimp.ccminer.org/bench?algo=lbry&chip=0
says that a gtx 750 ti has more hasrate than my card :/

Despite the lower model number the 750ti uses a newer architecture, faster and more efficient.

How can i compile that source code ?!!

[Epsylon3]

binaries are now released :

https://github.com/tpruvot/ccminer/releases/tag/1.8.0-tpruvot

[PeaMine]

I'm using Ubuntu 14.04 and Cuda 7.5 trying to mine LBRY
GPU #0: scanhash_lbry:140 invalid device function
I also tried 3.0 and got the same error.

[Epsylon3]

was tested on SM 3.0 and 3.5, it should work, use ./build.sh for a proper reconf

x86 binarie is faster by 5% versus the x64 binarie, talking about lbry

[rednoW]

nvidia 840m (notebook) - 27mhs lbry ))

Thanks, I also tried using build.sh after making the changes to the Makefile.am but same issue.
Do you happen to know the current steps for a GeForce GTX 780 Ti ?
Git clone, cd into folder, edit makefile, ./build and also manually doing the build and make steps produce the same error.
It properly compiles however and runs, but that error spamming produces no hash.

i think neoscrypt can see a farther optimization or fix don't know, because right now you need 2GH on the core to have 1MH, which is too much, also very power hungry compared to other algo

it should in theory touch 1M without that heavy oc, and around 1200 with oc, in fact in linux(using djm34 version) it reach 1150 with the same oc

[PeaMine]

I ran ./build with Sudo, for whatever reason that fixed it.

[Epsylon3]

i guess it was a previous build with root... that disallow the cleanup of temporary build files
