This realase quick test, 750Ti +%3,with 970 -%6 decrease ...

Congrats, and tx for the beer biggest one i received this year...

1. Download and install visualstudio 2013 express (free)
2. install cuda 6.5
3. download the sourcecode from git.
4. Open the project file (.sln)
5. Select release in the combobox on the top.
6. Press play

-neoscrypt 7% faster on the 750ti and 4% faster on the gtx 970
-fixed crash in neoscrypt
-Stop mining when disconnecting (fixed by pallas)
-tiny speedup quark


1.5.57(sp-MOD) is available here: (25-07-2015)

https://github.com/sp-hash/ccminer/releases/

The sourcecode is available here:

Works fine, thanks! :-)

good luck with visual basic

Is there any tutarial to create a miner with latest commit? I knew that i need cuda,visial basic and cc miner .I downloaded all but i don2t know how to do ))

Submitted an optimalization in neoscrypt.

7% faster on the 750ti  (+11KHASH)
4% faster on the 970 (+20KHASH)

Yeah i'd like to take a look

I successfully compiled this build on OSX 10.10 and hashing away on a GTX 970 if anyone is interested in this build!

Yep. Closed case > small space for airflow > needs more pressure.

A closed case will need very powerful fans, drawing a lot of power, decreasing global efficiency.

Sorry, i'm not strong neither in gcc nor in osx ... maybe this thread will help http://stackoverflow.com/questions/14898003/enable-openmp-support-in-xcode-4-6

Thanks!  I notice in the log when I run ./configure it says:


I installed the latest gcc-5 with homebrew via:  brew reinstall gcc --without-multilib

How do I get it to compile with OpenMP support?

omp.h is a header file for OpenMP threading technology. There are multiple ways to organize threading (multiple lightweight processes) in computer system: POSIX threads (pthreads), windows API, OpenMP etc.

You need a compiler with OpenMP support to compile this (or to turn that support on in config)

Thanks!  Definitely getting on the right path here.  It compiled for a long time and gave a ton of warnings, but then finally halted on this error:


EDIT:

I found the file in /usr/ folder.  I just copied it to the root ccminer directory along with malloc.h and now its compiling.....fingers crossed.

BTW, I applied this code fix to the sp-hash fork.  When I tried to apply it to your fork, it gave a bunch of errors.


UPDATE:

Now it halts on this error:



UPDATE 2

I used macports instead of homebrew on a fresh osx install and I was able to get gcc5 with openmp support enabled.  I also had to install the CUDA 6.5.27 toolkit for compute 5.2 support.  I did the code fix that Epsylon3 suggested and am now compiling.  Also had to do chmod 775 on install-sh for some reason (it was saying permission denied).  I am also noticing MUCH less warnings while compiling.  Fingers crossed....again!

UPDATE 3

SUCCESS!!!!!!!!!!  I cant beleive it, took me forever and alot of forum searching but I have it successfully compiled and hashing with my GTX 970 on OSX 10.10.  MASSIVE improvement over the ccminer 1.2 from John Chapman.  I was getting 4-4.5 MH X11 on that build and now I am getting 7-7.5 MH X11. 

Epsylon3, you got a little BTC coming your way for your help.  If anyone wants this build of ccminer sp-mod pm me and I'll help you out.

agreed ...

ours cool much more efficiently in a closed environment now than an open one - with the inital prototype closed design we have currently setup ... we already have server cases that do the same thing - but at m,any thousands of dollars each ( without components ) for high grade server cases and redundant psu - its worth the development of a cheap alternative design ...

this frame is taking a LONG time to get right - but will be a very cheap alternative to those servers cases - with a similar cooling system ...

solid aluminium tube frame - and hardened perspex - with high powered fans for tunnelled front-to-back air throughput ... thats our aim ...

anyway - back to work ...

edit - just to make sure if anyone asks ... yes - we have a 5ru case ( and 3ru - though its too tight for the cards which looks like a 4ru case may be the better way to go ) being tested for efficiency and airflow as opposed to 'our' designed frame and working systems ...

so far - a 5ru with usb 3.0 cabled risers and modified railing system may be the best way to go if going with the 'rady made' cases - or the in house designed frame we are getting together ... guess which one we are opting for ...

so we actually can say that cooling works in practice rather than just theory ... still working on the finer details of the frame and adding a few more adjustments ...

the rebuild of the farm WILL comprise of the finished frame design ...

afaik, process/thread affinity didn't exist at all in the early versions, so unless there are optimizations that specifically REQUIRE it, it should theoretically be ok to remove/disable it for OS X

spreadcoin can be pool mined too sp ...

code just needs to be changed at the pool end ...

i was using your spreadminer ( v8 ) to mine on a private pool for months - which is why i gave you the headache trying to compile it under linux the last time if you recall ...

there is also a spreadcoin pool that ocminer created - but only with his miner - NOT with yours ( which is no where near as optimized as your miner ) ... believe me ive tried ...

its one of the arguments i have put forward to the spr community - and well - its sorta just being heard about 'maybe' looking at a pool / multimine scenario ... maybe ...

im all for it if you wanted to know - so i support spreadx11 all the way ...
