sorry guys, version 6 is broken. I will be fixing it today, and add some more hash as well.

Spreadminer 7 is sendt to the donators.

- Fixed the hash
- fixed the makefile (linux)
- Rewrote Blake185
- some small tuning

0.6% faster than build 6 (750ti)

i'm running your wirlpoolx miner you release, is it normal that the pool side is reporting half the speed that ccminer is displaying, i tried both suprnove and noncepool.

i copied the files directly to the spreadminer7 folder and it seems to have started the compile ...

if the ccminer-spmod is anything to go by - this should take a little bit of time to finish ...

ill keep you informed in the next 15-30mins as to how this goes ...

one question though - does this miner run via a pool ( like tsivs one does ) ? ...

There are spelling errors in the makefile.am You need to rename these files:

spreadx11/x11_luffaCubehash512_cpu_hash_64.cu rename to spreadx11/cuda_x11_luffa512_Cubehash.cu
spreadx11/cuda_jh512Keccak512_cpu_hash_64 rename to spreadx11/cuda_jh512keccak512

keep the filename, but rename filename in the makefile. Cases are important, so you need to rename the cuda_jh512keccak512 with a small k in Keccak

it compiled after i changed the filenames as per your instruction in the Makefile.am file - though the second file required the .cu extension ...

ive now moved the compiled spreadminer to one of the production systems for testing ...

there is an improvement in performance - though not as much as i would have hoped using stock clocks per gpu - but nonetheless - an improvement in comparison to tsivs miner ...

below are the output of both the currently running spreadminer-tsiv and also the newly compiled spreadminer-sph both using the -x 20 parameter ( they are machines exactly the same specs ) ...

so as you can see there is a marked difference between the two workers ...

ill now propagate the latest spreadminer-sph across the farm and see how they perform overnight ...

tanx again sp ... this will help a great deal overall ...

ill now propagate the latest spreadminer-sph across the farm and see how they perform overnight ...
tanx again sp ... this will help a great deal overall ...
#crysx

I run without launchparameter (default is set to -x 5 on the 750ti). The 750ti will reduce the clockspeed if the cards get too hot. Lower intensity might be bether in the long run. I also think that 32bit builds will be faster. My windows compile (x86) is performing much bether.

it compiled after i changed the filenames as per your instruction in the Makefile.am file - though the second file required the .cu extension ...
ive now moved the compiled spreadminer to one of the production systems for testing ...
there is an improvement in performance - though not as much as i would have hoped using stock clocks per gpu - but nonetheless - an improvement in comparison to tsivs miner ...
below are the output of both the currently running spreadminer-tsiv and also the newly compiled spreadminer-sph both using the -x 20 parameter ( they are machines exactly the same specs ) ...

I run with -x 5. The 750ti will reduce the clockspeed if the cards get too hot. Lower intensity might be bether in the long run. I also think that 32bit builds will be faster. My windows compile (x86) is performing much bether.

ive changed the parameter to -x 5 and it seems to perform about the same ... so ill keep it at that ...

as for the x32 builds ... ill have to test that another day - as ill setup a x32 machine ( fedora 19 or 20 x32 ) and build it from a fully 32bit platform ...

what other commandline parameters do you think would benefit the hashrate / processing? ...

btw - just a small thing - but the title still says spreadminer 5 Wink

Different intensity parameters for different cards.

For the 750ti -x parameters should be a multiple of 5
for the 750, 960,980 -x paramameter should be a multiple of 8
and the 970 -x parameter should be a multiple of 13
