CCminer(SP-MOD) Modded GPU kernels.

[chrysophylax]

fixed it now

No GPU codechanges in this version from build 24

- fixed command output in benchmark mode
- fixed hashrate on some pools. coinmine.pl, suchpool.pw etc.

The 25th public beta(windows executable) is available here: (05-jan-2015)

http://www.filedropper.com/release25

The sourcecode is available here:

pull - compile - test ...

see how we go ...

SP_hash v25--

I carefully cloned from git on both my 750ti rigs.  My faster rig has been running version v24 with no problem, no crashes.  I reverted my slower rig to tpruvot v1.5.2-git after several crashes, and it has run over 24 hours without rebooting or restarting. 

I restarted both rigs with v25 a few minutes ago.  The slower rig clocks in initially at 18,045kh/s, and the fast rig clocks in initially at 18,445kh/s.  However, while I was writing this, the slower rig dropped to ~300kh/s.  I will again revert this rig to  tpruvot v1.5.2-git, but will wipe the disk and reload the OS tomorrow.  The faster rig is clocking along nicely as before.

I am considering upgrading the CPU on the slower rig.  The systems are nearly identical, except for the card models and AMD CPU models.

Also, the 10 second delay on shutdown (thread closure) was noticable when I switched between ccminer versions.

My rig went down total 30kh/s quark but my 3 cards on this computer went up 30kh/s.

Down on the pool? try to restart the miner. The result vil vary abit for every run. I think it has to do with alligment of buffers but I am not sure. 10/5500 is 0.02%

I tried X11 on my rig asrock 81 got 18,406 kh/s
The pool is down for quark. Will try again later.
EDIT: also quark algo does jump around a little.
Off topic but 2 months ago they were doing 300 btc a day 1-1-15 they started pumping out 4,000 a day 2 a minute ...the big drop in btc price maybe and panic sale.

With BTC price = trash, nothing is profitable anymore.

This is correct

its THIS that keeps it dead ...

there was a time when 'the market' ( ie 'the people' ) actually believed that btc was its OWN monetary unit and NOT a commodity for the government controlled fiat currencies ...

a time when btc was its OWN market - its OWN system - its OWN way of dealing selling buying and profiting ...

oh - hang on ... that time is still nigh ...

as i posted on @cryptobucket ...

no bloody wonder satoshi went underground ...

people have just 'lost' the whole ideal and intention that btc was built in the first place ...

ho hum ... the governments have won ...

for now ...

#crysx

I´m so disapointed, hopeless, now that Bitstamp get "hacked" as they say (Mt.Gox #2?), BTC price crashed, not in a good wave in 2015.

I think sooner or later things will change, to mature or simple to disappear for BTC.

they also said, they will reimburse back... (and btc went down before the announcement)

found an issue in build 25 when blocks changes often.. More rejects. New fix comming today.

[Handofmidas]

Tested release25 now, I think we're getting there! Hashrate is now recognized correctly as far as I can tell, fluctuates around the real hashrate as it should. Awesome job SP, here's the graph:

[sp_]

More hashrate is comming. I have optimized blake 25% faster.

[sp_]

Submitted the optimized blake kernals to gihub.(25% faster)

I had to split the kernals and implement 2 seperate implementations. one for the x series. x11,x13,x14,x15,x17 and one for the others, quark, nist5, jackpotcoin etc. In the x'series implementation I moved some precalculation  from const mem into the instructioncache. I also improved the uint2 implementation.


Building release 26

results on 750ti: (up from release 25)

x11 +30-50 KHASH
quark +50-100 KHASH


970 and 980 untested. Please test if you have time

I'm not sure if you caught my earlier message about releases.  When you made the r26 commit (86dd73f) and updated the version numbers in cpuminer-config.h it only reflects this change for windows builds.  The first line of configure.ac needs to also be changed for linux builds.

Didn't test much, but I think my 2 970s were getting about 13000 each.  Doesn't seem like they're doing as well as they could, but then again I haven't really mined quark on them before so i don't have previous numbers to compare them to.

[sp_]

I tested version 23 on the 980 and it made 15.5 MHASH on stock clocks. but build 26 should be faster.
13MHASH@970 is very good.

Sgminer does 5.6MHASH on the AMD 290x

I am working on a private spreadcoin miner. Anyone interested in paying for a boost? 30-40% faster

[sp_]

100MHASH spreadcoin earnings with the current difficulty:

Calculation result:
Calculating for period:   Day
Coin mining:   358.83607091 SPR
Pool fee:   0 % / 0 SPR
Coins to get:   358.83607091 SPR
First exchange to BTC:
Exchange rate to BTC:   0.00028005 BTC per SPR
Exchange fee:   0 % / 0 BTC
% for transfering to wallet   0 % / 0 BTC
I'll get BTC:   0.10049204 BTC
Exchange to USD:
Exchange rate to USD:   285.512 USD for BTC
Exchange fee:   0 % / 0 USD
I'll get USD:   28.69168332 $
Withdraw in Fiat
Exchange fee:   0 % / 0 USD
Cash, USD:   28.69 $

Spreadcoin pays 5-10 times bether than x11 mining per MHASH.

They're Gigabyte G1 cards so they should be a bit higher than most, but I haven't had a chance to verify that's the rate the pools are getting.  If so, good job.  If I can manage to keep my 12 750s and 2 970s running on the positive side of profit that would be great and I'll donate what I can, but it may come too late since I might need to sell everything for cash soon Too much lost btc in scams, exchanges, and bad timing recently.
