[ANN][Groestl/MyriadGroestl] Pool closed

[srcxxx]

DMD transactions are sent out, but they are either not being confirmed or are confirmed very slowly.
I would recommend to not mine DMD for now until the network stabilises.

You might want to try saffroncoin on port 60002 (myriadcoin-groestl algorithm). They are going to have block reward halved in a few days.

OK, I am pretty sure that Diamondcoin on my pool is on the correct blockchain (transactions are visible in Diamond block explorer + when I synced Windows wallet as per steps on DMD OP, I can also see transactions).

I hope it will stay this way. We'll see.

As for the previous payouts... I have about 300 DMD that were not paid out while DMD blockchain was stuck. I'll pay them out manually once the network settles down.

PS: The automatic payment should be working ok now, for example see: http://diamond.danbo.bg:2750/tx/1ac84c0f2ee8970054fb18460948b7430efd7680ad021ae3689e4d1e9951ba11#i6

Thanx for the effort, srcxxx! I hope quite a few of those 300 are coming my way, mined about 95Mh/s for some 30h, only 1,7 in payouts...

These are the DMD payments that I sent 5 minutes ago for the time that payments were stuck (31 July - 1 August).

If you are not in the list, please PM me with your DMD wallet address and hashrate (don't write in the thread), I'll check the logs and we'll resolve this.

Just wanted to let you know that I'm working on further optimizations almost every day. It is really hard to squeeze more MHs. I tried 2 other algorithms and both achieved worse results.
I'm hoping to get a 10%-30% speedup before I give up, so I'll keep on trying.

Today I was able to optimize the existing algo a tiny bit. Perhaps 1% - 3%.

Below are BOP files for R9 290 (Hawaii).
groestl
myriad-groestl

I'll try to optimize it a bit more and once finished, I'll do another release and include other videocards (1-3% is not worth a whole release).

Thanks

[katak]

Thanks a lot for your great job !

Hi all!

Some good news.

A new version of grs-sgminer will be released within a couple of days:
* merged optimized kernel (dynamic switching between groestl and myriad-groestl algo, no need to restart the miner)
* optimized kernel hashrate improved a bit (33.6 vs 32.9 on Myriad and 20.5 vs 19.8 on Groestl [R9 290 TriX @ 1170 Mhz])




Also TrinityCoin (myriad-groestl) has been added on port 60003. Not sure how profitable it is, probably not so much. But it is traded at bittrex.

BTW, if you know of any other groestl or myriadcoin worth mining - please let me know and I'll add it.




And finally, I've added links to the coins threads on the main page (http://cryptohunger.com:81/).
MYR, SFR, GRS and DMD have links to calculators. I did some calculations for a single R9 290 using optimized kernel.
BTC reward per day is:
0.00040709 if you mine GRS
0.00102124 if you mine DMD
0.00112975 if you mine Myriad
0.00539810 if you mine Saffron


PS: Let me know if you are interested in a multipool with payouts in BTC.

Thanks!

hi

no change with 1.3  or 1.3M  15.7mhs on 6970,  better than "older" 15 mhs.

i'd like 18-20  mhs 

good job

Weird... I can't reach 15MH with 6970... -g 4 slightly improves speed but top is 13MH, older badman built sgminer 4.0 (from march 26th) gives 15Mh on 6970

I'll try to change opencl files to see if there is difference

Hey, fellow krypto geeks!

DOKDO?? It's alive and well. I exchange regular emails with the lead dev. But the English-language community is tiny, so trading is manual. But I have been following the coin for months now, and have confidence in the dev team. Indeed, we have had some bad luck (the first English-language exchange went belly up . . . ); but apparently btc  kor will be online withing days.

Thank you for your optimized pool for Dokdocoin!
We got a really busy time in korea but in two weeks we can start to do more things for Dokdo and
cryptocoin world
Cheers!

Hi!

With Groestl and Myriad Groestl algorithms, you usually need to overclock GPU quite significally. For example, I'm using 1170Mhz on R9 290 (where standard frequency is 1000Mhz).
This happens because these algorithms don't use power hungry memory exchange operations and thus GPU produces less heat and stays within TDP bounds.

I don't have 6970, so cannot check for sure.

What I'd recommend is to take your "old badman's sgminer 4.0" exact command line, change algorithm to "myriadcoin-optimized" and pool to stratum+tcp://cryptohunger.com:60001 and see what hashrate you'll get.
If it'll be less - then grs-sgminer is not well suited for 6970 videocards and It'll be great if you could post your results before stopping with grs-sgminer.

Thanks

Pretty new to Linux here but I have to say something at least.

I made a build from your github repository today.
It was the easiest, CLEANEST build I've done in my 3 months using Linux. (no errors/warnings)

It looks like you spent some time developing and delivering a quality product.

Nicely done

Running on older sgminer speed is 14.1MH/s with 14.6 and 14.8MH/s with opencl files from 13.12
Same conf&bat run from grs-sgminer gives 12.3MH/s

Running myriadcoin-optimized the speed is a bit lower ~ 11.9-12MH/s

Also tested on 5850 - no gain either. But on 290 the speed increase is stunning

Hi!

OK, looks like the kernel is not good for the old hardware that you mentioned.
So I don't recommend that you use grs-sgminer.
I'm quite surprised that just plain myriad-groestl is slower in grs-sgminer, because it is based on OpenCL kernel from sph-sgminer.
Anyways, I'm working on completely different groestl algo and hoping it'll be a lot faster.
In the meantime, I recommend that you use your old miner and some other pool.
I will post to coin threads once I have a faster miner.

Thanks for your time.

How many threads are launched per shader core? You mentioned that thread-concurrency is no longer used... but on 6xxx radeons that parameter is useful - maxing out at shaders*5
It seems by default when using simple myriad-groestl, your version is defaulting to shaders*2.

"thread concurrecy" is actually a buffer size, which is used only on scrypt, as far as I now.
surely not on groestl.
