[ANN] rhminer - an optimized CPU+GPU miner for PascalCoin

[2h4u]

*NEW RELEASE*

Would you like to ignore SIGWINCH or handle the signal appropriately? There's a problem to run the miner inside the screen terminal multiplexer. I run miner with screen (screen -dmS yaddayadda), deattach screen, attach it back, then miner exits.

I found a workaround: run it with unbuffer command (man unbuffer).

Would you to handle SIGWINCH appropriately? There's a problem to run the miner inside the 'screen' tool.

I use  headless servers (on a budget).  I just SSH into them.

Does this affect me?  Seems to be running fine from remote terminal session.

How'd you run the miner--screen or tmux? Or just nohup?

There is no miner--screen anywhere.  I use Linux.  Is this a Windows question?  Windows/Mac OS doesn't even come with a proper SSH server/daemon.

Sorry for the confusion.

Sorry for the confusion.

Oh dear. At first, '--' is a punctuation mark, we call it an 'em dash'. At second, screen and tmux are commonly used Linux terminal multiplexers. https://linux.die.net/man/1/screen, for example.

My mobile phone got rick rolled.  Chrome popups.  I reinstalled Chrome and installed Ad Buster.

-----

I ran ./rhminer from the terminal.  I didn't notice any issues. 

I am not new with Linux, just never heard of this out of millions of commands.

On Ubuntu, the unbuffer program (from the expect-dev) package did the trick for me. Just run:

unbuffer your_command

and it won't buffer it.

Found that online.  I guess that's the workaround for now.

@all the linux issues are fixed now.
There is no exit from main thread anymore and the zip files contain an executable now (no need to chmod +x) anymore.

@everyone
Version 2.1 is out and much FASTER.

* Optimized RandomHash2 with up to 80% more speed. (On some system rhminer 2.1 is up to 250% faster than official miner)
* Fixed linux binary where main thread was exiting after miner startup.
* Linux zip files now contain rhminer as an executable and not a simple file.
* FIxed windows packages and removed extra folders

Download latest version here : https://github.com/polyminer1/rhminer/releases

Thank you.

I have been using v2.0 with unbuffer.

It is was reliable if ran correctly.

V2 very fast and very stable BTW on 3 different CPU architectures.

Here are my "average HRs".

4x Kali Linux.  1 Chrome OS (DEV) w/ Linux.

I have 1 more Chrome OS device, but (beta build for 7" GPD Pocket (Atom X7) the charger does not work while it's on.

Posting this for reference to v2.0

Thank you,

BTW:  I have looked into ANY way to disable the GPU to use the Intel HD only - 650 GT Apple Edition including BGA rework removal.  It's impossible to bypass it.  Stupid PCB layout.

Kali Lite on the MBP.  No difference.  Can't drop into the terminal.  Xwindows uses the nvidia graphics no matter what.

Tnx for the report.
You should try 2.1 now, it's up to 80% faster !

I did.  I still have 1 issue. 

My MBP Retina 2012 keeps overheating.

Serious question.  I have few older spare water coolers (up to 200 Watts+ TDP).

Is there a way to attach them to the CPU and use it as a desktop?

It keeps throttling (in the Linux console log) every few seconds.

CPU throttle.  Slows it down to 1/2 the speed it should be.

I have a syringe of KPx thermal compound.  I have used it on everything and it works.

Ryzen 7x with stock cooler overclocked.  On air.  Never crashes and it never overheats.

[tlaskows]

I redid the thermal again.

The new cheese grater design.

It runs much better.  No joke.

2012 MBP Retina 15".  CPU performance x2.

Version 2.2 - New optimizations up to 55% faster.
*Added major optimizations. (55% on Platinuim, 50% on i7 and i5)
*Tested on i5, i7, Epic and Xeon
*Added version in log and submit chrono

Thank you.

I do realize Ryzen 7 X is desktop - consumer version of the Epyc.

I have to keep it running below 60 degrees CPU die.

Will check for performance gains.  I paid around 300 Fiat for it.  Still fastest one even than a more powerful Xeon.

Cheers.

@everyone New version that fixes the connections on openpool.

Version 2.2b - Removed pascalpool.org from DevPool list
*Improved pool connection
*code cleanup and minor improvements (linux and macos)

Cheers.

Using on Linux get a segfault core dumped and it happens on 3 out of 4 machines

[polyminer1]

What version of linux and what version of rhminer ?

[dfish987]

Lubuntu 19.10 and both rhminer 2.2 and 2.2b
