hi dev..can you add Equihash 192.7 algo with your cpuminer ...is it possible? thanks

hi dev..can you add new algo scrypt8k

https://bitcointalk.org/index.php?topic=5163850.0

https://github.com/LiteNoteProject/LiteNote

thanks for your support

Try -a scrypt:8192

If that doesn't work, it's a custom version of scrypt which would be too much work.

Scrypt8K is the usage of the scrypt hashing algorithm with the variables N, r, and p set to 8192, 8, and 1 respectively.

A second question without following up on your first, you're just trolling.

Thanks for the info.

I'm not very familair with the scrypt code but I took a look. Based on the name of the function
"scrypt_1024_1_1_256" I assume those are the parameters N, r, p & hashsize. 1024 is the default
N but can be changed from the command line. I found no mention of r or p paramenetrs in the code
so I assume they are hardcoded at 1, as implied by the naming of the function..

This would suggest that "-a scrypt:8192" won't work for scrypt8k. Have you tried?

This looks interesting, the code has the same origin but cpuminer-opt's version of scrypt is
Pooler's code highly optimized for the original scrypt algo. I can't simply copy & paste wownero
but I might be able to use it to find all the places in the Pooler code where R needs to be inserted.
This is a lot of work because Pooler has multiple implementations for different CPU architectures
and uses ASM. I'm weak in x86 asm so it will be diffficult.

I've opened an issue for it but there's no guarantee I'll ever do it.

If you want help you'll have to provide a lot more info than just a compile output
out of any context.

Also if you don't understand that error, you're probably in over your head.

I have compiled cpuminer to Windows and Unix, I am using sha256 bitcoin algo (pow)

The Unix version is doing around 2000-3000 Kh/s
The Windows version is doing around 500-800 Kh/s

Using the same source code... same machine, same specs (dedicated servers with the same CPU)
I have tested with about 10 setups.

Anyone else has the same issue?

[TheWolf666]

please help

With Windows, use Visual Studio 2013

Both your posts make no sense, cpuminer-opt will not compile with VS.

Both of you RTFM!

Yep right, sorry. I mess up with another cpuminer ( https://github.com/tpruvot/cpuminer-multi )

hello,
how to compile it in windows?

This is a heads up for a proposed user interface change to cpuminer-opt.

I am intending in the next release to remove -R as a shortcut for the --retry-pause option:

Code:

  -R, --retry-pause=N   time to pause between retries, in seconds (default: 30)

I have plans to use -R for something else, --retry-pause will still be avaiable.
Retry is a rarely used option as most users prefer to exit and failover to a backup
pool when a connection is lost.

Until -R is repurposed its use will produce a warning message.

I Initially declined to include cpupower algo in cpuminer-opt due to a number of  concerns.

Algo bloat: the number of supported algos is now around 100, that's 100 different
options for the -a argument. Many are almost identical with only parameter differences.

Single coin algos: I want to avoid algos that are tied to one specific coin and unlikely to be
used by any other coin in the future.

Algo branding: I prefer generic algo names instead of names that are closely associated with
a single coin.

Planned obsolescence: Coins that have plans to change algos are more work to support.

Unfortunately cpuchain/cpupower hits on all those points. The devs have expressed a desire
to maintain a tight coupling between the coin and algo, objected to a generic and more
descriptive algo name, and have plans to change algos.

All these factors led me to conclude the algo did not have much of a future and would likely
become obsolete.

Given the level of control the devs wanted over the algo I suggested it would be better to have
a dedicated cpuchain miner where the devs would have total control and freedom over their
algo of choice.

The existing cpuchain miner is forked from cpuminer-opt and can easilly import any missing
optimizations.

I'm looking at ways to simplify support for multiple algo variants to reduce the bloat and provide
some forward compatibility with new variants that don't require code changes.

-R option is deprecated

Plans have accelerated. There will be no grace period which would delay new features.
In the next release -R will have a totally different meaning, there will be no warning message.

cpuminer-opt-3.9.7 makes changes to command line options.

-R is no longer used as a shortcut for retry-pause, users must use the long option.

New options have been added to facilitate mining algos based on yescrypt or
yespower with different parameters:

Code:

 -N, --param-n         N parameter for scrypt based algos
  -R, --param-r         R parameter for scrypt based algos
  -K, --param-key       Key parameter for algos that use it

These parameters can be used to mine existing algos or new algos.
Existing algos may still be mined using their original unique name without extra parameters.

Any new algos based on yescrypt or yespower which only differ in parameters can be mined immediately
without requiring a new release of cpuminer-opt by using the generic algo name and specifying the parameters.

For example the recent cpupower algo can be mined using the following parameters:

Code:

-a yespower -N 2048 -R 32 -K "CPUpower: The number of CPU working or available for proof-of-work mining"

Edit: Be carefull with the key, it's very long in this case and contains spaces and special characters, the quotes are necessary.

Parameter values are determined by the developpers of the coin and/or algo and should be listed in the coin's specifications
or mining instructions. Cpuminer has no knowledge of the parameter values except for algos previously
defined with a customized name.

Only the N parameter is supported for scrypt, R is harcoded with 1.  -a scrypt -N n has the same effect as -a scrypt:n.

[joblo]

Copy & paste the entire key including the quotes.
