    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.

    Download: Zcash Nvidia_Miner v0.6.2

    Version 0.6.2 update:

    - fix ssl handshake failures
    - fix device selection bug introduced in 0.6.1
    - make linux performance improvements introduced in 0.6.1 optional
    via 'mq-solver' parameter (due to issues on some systems)
    - improve device initialization on large systems

    Avg: average solutions per second
    I/s: iterations per second done by the GPU
    S/W: efficiency - average Sol/s per Watt
    W: power consuption in Watt
    last 3 colums: <shares per minute> <accepted shares ratio> <network latency in ms>

    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


    BIG THANKS TO SWISSTRADER for providing access to hardware.
