[ANN] dstm’s ZCash / Equihash Nvidia Miner v0.6.2 (Linux / Windows)

[Likvider]

#################################################
# 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.

Features:
To get help just start zm without any arguments

Code:
ZM 0.6.2, dstm’s ZCASH/Equihash Cuda Miner

Usage:
zm --server hostname --port port_nr --user user_name
[–pass password] [options]…
zm --cfg-file[=path]

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

Options:
–help Print this help
–list-devices List available cuda devices
–dev Space separated list of cuda devices to use.
If this option is not given all available devices
are used.
–time Enable output of timestamps
–color colorize the output
–logfile [=path] Append logs to the file named by ‘path’
If ‘path’ is not given append to ‘zm.log’ in
current working directory.
–noreconnect Disable automatic reconnection on network errors.
–temp-target =dev_id:temp-target[,dev_id:temp-target] …
In C - If set, enables temperature controller.

The workload of each GPU will be continuously
adjusted such that the temperature stays around
this value. It is recommended to set your fan speed
to a constant value when using this setting.

Example: --temp-target=0:65,2:70
–intensity =dev_id:intensity[,dev_id:intensity] …
Reduce the load which is put on the GPU - valid
intensity range ]1.0-0.0[.

Example: --intensity=0:0.893,2:0.8
–telemetry [=ip:port]. Starts telemetry server. Telemetry data
can be accessed using a web browser(http) or by json-rpc.
If no arguments are given the server listens on
127.0.0.1:2222 - Example: --telemetry=0.0.0.0:2222
Valid port range [1025-65535]
–cfg-file [=path] Use configuration file. All additional command
line options are ignored - configuration is done only
through configuration file. If ‘path’ is not given
use ‘zm.cfg’ in current working directory.
–pool =hostname,port_nr,user_name[,pass]
Setup additional failover pools.

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