I am a pool operator, and found that there is difficulty multiplier set for different algos in ccminer, may I know what is the reason behind that?

Code:

	switch (opt_algo) {
		case ALGO_HMQ1725:
		case ALGO_JACKPOT:
		case ALGO_JHA:
		case ALGO_NEOSCRYPT:
		case ALGO_SCRYPT:
		case ALGO_SCRYPT_JANE:
			work_set_target(work, sctx->job.diff / (65536.0 * opt_difficulty));
			break;
		case ALGO_DMD_GR:
		case ALGO_FRESH:
		case ALGO_FUGUE256:
		case ALGO_GROESTL:
		case ALGO_LBRY:
		case ALGO_LYRA2v2:
		case ALGO_LYRA2Z:
		case ALGO_TIMETRAVEL:
		case ALGO_BITCORE:
			work_set_target(work, sctx->job.diff / (256.0 * opt_difficulty));
			break;
		case ALGO_KECCAK:
		case ALGO_LYRA2:
			work_set_target(work, sctx->job.diff / (128.0 * opt_difficulty));
			break;
		case ALGO_EQUIHASH:
			equi_work_set_target(work, sctx->job.diff / opt_difficulty);
			break;
		default:
			work_set_target(work, sctx->job.diff / opt_difficulty);
	}

Epsylon3, do you plan to activate yiimp api?

weird question from a pool operator.
a multiplier is applied to stratum diff and may be different from coin to coin.
it's been like that for ages.
usually, a multiplier is set for a hashing algo when the first stratum implementation is made.
it's just a way to allow much easier shares for slow miners (compared to net hashrate).

Here is a feature request, please consider adding a ping display to the current pool. Either by running a ping periodically or how long it takes for queries back and forth. This would be very helpful for diagnosing the health of the pool you're connected to.

You can access ping through ccminer api

The difficulty showing in the coin daemon(i.e.,  MaxCoin- Keccak, Digibyte - Scrypt) isn't multiplied. If we apply multiplier there, the difficulty showing in stratum will not be the same as what reporting from the daemon. So we haven't set the multiplier in the stratum pool and that works fine in sgminer. But for ccminer, there is a default multiplier for Keccak. Our pool give 1024 pool difficulty to the miner and ccminer will submit all shares which has difficulty >8. And so the reject rate showing is >99%. If I set multiplier = 128 in the pool for Keccak which is the same as ccminer, this will cause sgminer not submitting shares as it is too difficult for them. Moreover, it may also cause the pool difficulty (~128000) will be larger than network difficulty (~1000).

multiplier is just a setting for the com between the pool and the miner.. nothing related to coin diff

I'm new to this mining thing, but i didn't think it was possible to mine Equihash (zcash, zen, zclassic) with this miner? If  incorrect I could use some help with the bat file, because I cant get it to work.

It is possible......... use .........  ccminer.exe -a equihash ..........
Although the hashrate for this algo is less in ccminer....compared to alternative miners available with 2% devfee.

Consider excavator, nicehash has done a really good job with this miner after all that dev work.  Not sure if you can mine anywhere but nicehash to be honest, but there is no fee as far as i'm aware and factoring in fees I see about the same speed.

how important is cuda for ccminer v2.2.2 (or generaly ccminer)
I installed regular nvidia driver (think it is 385..), and used v2.2

But version v2.2.1 have cuda9, and v2.2.2 have version for cuda 7.5 and cuda 9..
So i installed cuda 9 and drivers are fu*ked up.. Monitor can't work and TW is only solution to see what is going on.
Once I enter TW I see large files (like no drivers installed)

So I need to reinstall Windows 10 again, but wondering, should i install cuda 9, cuda 7.5, or just latest nvidia drivers?
IS there bust in preformance with cuda drivers ?

Since I got error with Visual Studio, when installing cuda 9.

Hello - this is my first post on this forum 

I am trying to mine VERGE XVG on ethos. I have updated to ccminer 2.2.2 and use NVIDIA GTX 1060's

However - I get the following message -  any help would be appreciated

RPC problem. Probably couldn't connect. Retrying in 2s
Getting work package...
Failed to submit hashrate
Dynamic exception type: jsonrpc::JsonRpcException
std::exception::what: Exception -32003 : Client connector error: lib curl error :7 -> Could not connect to http://127.0.0.1:8080/MyMiner

Anyone maybe know what I am doing wrong ?

Hi,

why this ccminer version has that low lyra2v2 hashrate?
I use one old verison where is default intesity set at 22 and hasrate is 70Mh/s at 1080Ti. With this version I cannot go over 60MH/s, because intesity is set to 20 and when I try go up ccminer crash.

That's not the same as showing it in the console when it's mining and are you sure that's a pool ping verse a ping to the ccminer client?

Yes Im questioning this also. I'm getting 185 mh on 2.2.1 and on nicehash miner with 1.7.6 I'm getting 214 mhs. this is substantial and driving me nuts if I want to mine mona coin or vert coin. whats up with this tpruvot?

anyone can help me with this error

For lyra2rev2 algo use this fork of ccminer 2.2, https://github.com/Nanashi-Meiyo-Meijin/ccminer gives much better result than stock ccminer.

For the developers,
just curious about one aspect.

You have setup CUDA threads to be 256 threads per block.

If they were just 1 thread per block, would the result of the computation still be correct?
So 256 is just for performance or is also a requirement for ccminer to correctly do its job?

Thanks
