#################################################
#  dstm's ZCash Cuda miner
#################################################

I've written it initially for my own purpose. It performs pretty well - so here it is.
Compatible with devices having Compute Capability 5.0 and greater i.e. it should run fine on Maxwell/Pascal GPUs.
Supports every server using the stratum protocol. If you have issues with certain pools pls. report them here.
Contains 2% devfee.
Suggestions are welcome.


Performance:
1080Ti 725-740 Sol/s
1070   440-450 Sol/s
stock settings


UI:
Here is a sample output mining on a rig with 7 GPUs.
GPU0: 1080Ti
GPU1 - GPU6: 1070

Code:
>  GPU0 42°C  Sol/s: 739.0  Sol/W: 2.85  Avg: 739.0  I/s: 390.1  Sh/s: 1.800  ++++++++++++++++++

Features:
To get help just start zm without any arguments

Code:
$ ./zm
M 0.5, dstm's ZCASH Cuda Miner

Usage:
 zm --server hostname --port port_nr --user user_name
    [--pass password] [options]...

 Stratum:
    --server         Stratum server hostname
                     prefix hostname with 'ssl://' for encrypted
                     connections - e.g. ssl://mypool.com
    --port           Stratum server port number
    --user           Username / Workername
    --pass           Worker password

 Options:
    --help           Print this help
    --dev            Space separated list of cuda devices
    --list-devices   List available cuda devices

    --temp-target    In °C - If set, enables temperature controller.
                     The performance of each GPU will be continuously
                     adjusted such that the temperature stays around
                     this value. It is recommended to set your fan speed
                     to 100% when using this setting.

    --telemetry      [=ip:port]. Starts telemetry server. Telemetry data
                     can be accessed using a web browser or by json-rpc v1.0.
                     If no arguments are given the server listens on
                     127.0.0.1:2222 - e.g --telemetry=0.0.0.0:2222

 Example:
    zm --server servername.com --port 1234 --user username

Scans clean with ESET, but dammit there's alot of new malware thats undetectable too... :/

no source you would share just for quick perusal eh? Sad

why the brand new account? you wrote a zcash miner but NEVER made an account here ever? :/

It's clean. It does only one thing, it mines ZEC.                                                                                                                  
Launch it in a VM and monitor everything u can to get confident.

Ah, I see. Malware seem to be a huge problem on this forum. I took a look for a description to setup a VM quickly. It seems it not that easy. PCI/GPU-Passthrough seems to be very hardware dependent - not that easy to setup. I've really no good idea how to provide security for you, without opening the source. Well I guess someone has to try it out and report. Sry, but I have no better ideas for this.

I've done some comparisons now. It seems there are not that many cuda miners out there.                                        
The fastest miner that I'm aware of averages at about 72 Sol/s on the GPU I've mentioned in the OP.

Quarx2k  That would be really a great benchmark.

Unfortunately it's currently written specifically for linux and uses direct OperatingSystem calls to be as fast as possible, to have very low cpu usage and to consume energy as little as possible. However if people are interested in a Windows version I'll port it. First we have to check how it performs on something faster then a 750ti Smiley However my test are very promising.

Why do you always compare with the second fastest?
Which one is the fastest one and how much sol does it give on a 750ti?

Oh Wink I wrote it a bit confusing. The second fastest is actually the fastest I could find. I called it second fastest because it's slower then mine miner. I've edited my posts now. Wink

Just finished benching(Couldn't find out how exactly to use --dev to enable all gpus, tried 012345 then 0,1,2,3,4,5 then 0 1 2 3 4 5 and still only one enabled)

GTX 1070 MSI Armor(Micron)
core +125 , mem+750

your miner: 340Sol/s
ewbf: 410Sol/s
ccminer/nicehash miner: 370Sol/s


A source code would be greatly appreciated.

Thx a lot.
                                                                                                                    
Actually that looks good, since I've never tested it on pascal class GPUs so there is zero optimization for them. So it looks really good.

What column in the output did u use when reading my Sol/s? "Avg" or "Sol/s"?                                                                        
Concerning the --dev option. Currently only one GPU per process is supported, however u could start different processes for different GPUs.

Thx, finally 1080ti Smiley                                                                                                          

1.76 times faster. That's a much bigger difference then I expected. Not sure if it's due to design or due to optimization. I'll have to take a closer look at pascal manuals.
Also it seems not to scale compared to a 1070.

Could u please run another test. Set your cpu-governor to performance mode this time. The miner is highly multithreaded. Since it scales so bad compared to a 1070 - it could be due to scheduling latencies. So if u have some time pls test with cpu-scaling governor set to performance.

Fee or nofee, open or closed source it wont make any difference because there is already open source cuda kernel, just noone is interested as of devs to improve it for free Smiley
Open source miners are dead.

Nice,                                                                                                                         
                                                                                                                               
so it's latency dependent. I'm not sure how much time u have. If u have some, I would compile some versions that should show where the bottleneck is. Also could u pls check the cpu usage. If u have some time for all this stuff Smiley ofc.
