It seems like I should be able to come up with a ridiculously fast implementation of Ethash.
After all, the illusion of Ethash'es memory-hardness hinges upon the false assumption that
algorithmically-generated DAG's are comparable to a series of true random numbers
in terms of randomness, which is just not true. I will publish everything
after I make enough money to buy a house in Berkeley...

I read it and laugh, again and again, thanks Grin

This is the best message from you, ever!
I must save it here as a quote...

I only work if there is an advanced payment. Too bad!

Actually, I am quite busy right now anyway.
I *think* I found a crack in one of the major algorithms.
If rumors are correct, somebody must have been taking advantage of it for quite some time now.

Oh will you stop teasing us all the time Tongue

OK, OK. I will disclose as much as I can. I am not going to reveal everything as I still need to pay my bills, though.

There is a critical flaw in Ethash'es memory-hardness as you can generate DAG on the fly with enough computing power.
This is probably impractical with GPU's, but it seems that it is quite possible with FPGA's and ASIC's.
I found an efficient way to represent an Ethash DAG with a memory footprint in the order of several MB's,
which is three orders of magnitude less than the original DAG. I might be able to implement this method
with Vega if I can squeeze everything onto Vega's 4MB L2 cache.

Wow, very interesting. You're knocking them out of the park bro! I've always loved your miner for all of the algorithms that it's been able to mine and now that you're adding more algorithms, it's even better. Thank you for all of your hard work. Cheers!

Fail to plan, and you plan to fail.

This sounds pretty interesting, as long as ASIC manufacturers arent reading this Cheesy

i hope this sees the light of day soon.

Zawawa there is a bounty for the fastest AMD miner maybe you will be interested.

He will get eternal bounty if stable and fast ProgPOW algo is added to GGS. Roll Eyes

So, what's the outlook, Zawawa? When can we expect the next mind-boggling release of GGS? Grin

I actually started porting the new miner to Linux in my (very limited) spare time.
I would rather release a complete miner instead of keeping fixing work in progress this time around.

THANK YOU FOR YOUR CONSIDERATION OF THE LINUX MINERS! --

I will wait patiently for a release. You deserve donations... especially from mining OS developers. --scryptr

Understandable.

Which begs the question...

When can we expect the next mind-boggling complete GGS miner? Grin

I tested your Ethash kernel on ethminer, it is a little faster them claymore kernel for about 0,5mhs - 0,8 mhs,

But with the timings for claymores kernel, the miner crashs at 1 min mining.

Congrats by the way Wink

Thank you. Actually, I updated the kernel and it is running even faster, especially on Vega.
I cannot do anything about BIOS mods for Craymore's, though. Tongue

I have installed AMD drivers which GGS requires, but I always get the same message about OpenCL and being redirected to AMD Adrenalin drivers webstie (which I have installed). Why?

PS I have no Windows 10 April Update installed.
