Quickstart:
|
|
----------
|
|
|
|
First time mining verthash or don't have a Verthash data file:
|
|
|
|
--algo verthash --verify --url ...
|
|
|
|
Verthash data file already exists:
|
|
|
|
--algo verthash --data-file /path/to/verthash.dat --url ...
|
|
|
|
|
|
Background:
|
|
----------
|
|
|
|
Verthash algorithm requires a data file for hashing. This file is
|
|
static, portable, and only needs to be created once.
|
|
|
|
A Verthash data file created by VerthashMiner can also be used by cpuminer-opt
|
|
and used simultaneously by both miners.
|
|
|
|
Due to its size >1GB it is recommened one data file be created and
|
|
stored in a permanent location accessible to any miner that wants to use it.
|
|
|
|
New command line options:
|
|
------------------------
|
|
|
|
cpuminer-opt adds two new command line options for verthash. The names
|
|
and some behaviour is changed from VerthashMiner.
|
|
|
|
--data-file /path/to/verthash.dat
|
|
default when not used is verthash.dat in current working directory.
|
|
|
|
--verify
|
|
verify integrity of file specified by --data-file, or if not specified
|
|
the default data file if it exists, or create a default file and verify it
|
|
if one does not yet exist. Data file verification is disabled by default.
|
|
|
|
Detailed usage:
|
|
--------------
|
|
|
|
If a data file already exists it can be selected using the --data-file
|
|
option to specify the path and name of the file.
|
|
|
|
--algo verthash --datafile /path/to/verthash.dat --url ...
|
|
|
|
If the --data-file option is not used the default is to use 'verthash.dat'
|
|
from the current working directory.
|
|
|
|
If no data file exists it can be created by using the --verify option
|
|
without the --data-file option. If the default data file is not found in
|
|
the current directory it will be created.
|
|
|
|
--algo verthash --verify --url ...
|
|
|
|
Data file creation can take up to 30 minutes on a spinning hard drive.
|
|
Once created the new data file will be verified and used immediately
|
|
if a valid url and user were included on the command line.
|
|
|
|
A default data file can be created by ommitting the url option. That will
|
|
either verify an existing default data file or create one and verify it,
|
|
then exit.
|
|
|
|
--algo verthash --verify
|
|
|
|
A data file will never be created if --data-file is specified. The miner
|
|
will exit with an error if the file is not found in the specified location.
|
|
This is to avoid accidentally creating an unwanted data file due to a typo.
|
|
|
|
After creation the data file can moved to a more convenient location and
|
|
referenced by --data-file, or left where it is and used by default without the
|
|
--data-file option.
|
|
|
|
Data file verification takes a few seconds and is disabled by default.
|
|
VerthashMiner enables data file verification by default and has an option to
|
|
disable it.
|
|
|
|
The --verify option is intended primarily to create a new file. It's
|
|
not necessary or useful to verify a file every time the miner is started.
