CCminer(SP-MOD) Modded GPU kernels.

Could someone plz tell me what   - C   does... I looked in the readme file and its not there.  Thx.

CPU MINING--

The "-C" command line flag enables the "CPU Mining" boost in sp_ 's branch of ccminer.  It makes a big difference in hash rate for some algos, as the cpu is  assisting the gpu in processing the data.  I remember chatting at you about it before.  As far as I know, sp_ 's branch is the only one that uses this fllag.

It increased my Quark hash rate about 500kh/s to 11.5MH/s with my GTX 960.       --scryptr

That's with an unoptimized CPU miner. If you want to co-mine with the CPU you could try cpuminer-opt.
It does quark at 1.2 MH/s on a i7-6700K. But I prefer to mine more CPU friendly algos.

I CO-MINE WITH CPUMINER-OPT--

I run 6 threads.  BUT, the "-C" flag allows the cpu to assuust/boost the performance of the gpu hash rate.  If you want a better explanation, you will have to ask sp_ .  In simple English, ccminer gets a better hash rate with the "-C" flag set at launch.  Results depend on the algo and hardware.  I use the flag in all of my launch lines.  And, I am usually runnning CPUminer-Opt at the same time, with only a small reduction in hash rate for both miners.     --scryptr

We were both wrong, I looked at the code.

-C actually has nothing to do with CPU mining, it only changes how the CPU and GPU are synchronized.

It is not implemented in other forks as it is selected automatically when appropriate.

JSON LAUNCH.CONF FILE--

The "-C" flag stands for the long form "cpu-mining" command that would be in a JSON format configuration file.  An example for ZPOOL follows:

{
   "url" : "stratum+tcp://mine.zpool.ca:4533",
   "user" : "COIN ADDRESS",
   "pass" : "rig1,c=COIN",
   "algo" : "lyra2v2",

   "intensity" : "21.3",   
   "cpu-priority" : "5",
   "cpu-mining" : "true"
   
}

This is called by a launch line like "ccminer.exe -c zpool.conf".  I was unclear as to what I meant by "cpu-mining", and with your focus on coding CPUminer-OPT, you possibly misunderstood.

The only fork of ccminer with this switch is sp_ 's, and it works.  It forces co-operation between the cpu and gpu that yields better hash rates.  Your code inspection is informative.  Apparently, auto-selection is not always working to yeild the best results.       --scryptr

-C improves the hashrate but use alot of cpu.

[joblo]

The "-C" flag stands for the long form "cpu-mining" command that would be in a JSON format configuration file. 

That's what the arg is called but not what it does. I had assumed it did what it said but it just uses more CPU
to be more responsive to the GPU which helps the GPU hash faster. The CPU doesn't hash at all.

So curiously, where are people getting 1MH+ on Neoscrypt and 25MH/s on Ethereum on a 1070?

I've been hunting around and Amph's quoted rates are no where to be found.

Just make sure you have one cpu core (including hyper-threading) per card or it can slow you down.  I have an i3 with 6 750 ti cards and it slows down the hash.

Why should the 2 cores in the cpu hash at all?? Bether to let the cpu aid the GPU's to reach the maximum output. -C is intelligent CPU hashing. Your miner is just HASHING .

Just finished watching the BREXIT TV debate.

Huge applause, when Boris Johnson finished the debate by promising voting for BREXIT, will become known as Britain's "Independence Day"!

First time, in many decades a UK politician has ever got that level of applause from a non-partisan audience.

Because it increases the overall hashrate of the rig if the CPU is powerful enough, but the priority for the CPU is to serve
the GPUs.

As someone else commented about dedicating one CPU thread per GPU, it should be noted this is more important when using -C.

About the Sc-Fi channel schedule:

the 2nd season of "Dark Matter" starts 4th of July, which was the best SC-FI series from 2015.

But, if you are into your Apocalyptic Futures, when humanity has been laid to waste and ruin:

"Wayward Pines"

Is pretty fun to watch
