Pleiades Prototype alpha

Is this the marking of the KNL or another form of "cluster"?

Hmmmm?

Just yesterday I have thrown the pleiades source code from my Sandbox (I have it still in the repository though), because
with the arulbero-EC arithmetics and my GPU hash160 implementation we have something better.

Having said that, both the KNL as well as the Skylake-EX with their AVX512 engines are a hell of a machine for EC arithmetics.
If anyone has these processors, I can provide a generator binary.
So if anyone is looking for a dedicated machine with quite some key generation performance:

KNL + GPUs (probably too expensive) or Skylake-EX + GPUs (less expensive, but still some bucks)

With these we're getting in the region of 100s of Mkeys/s per machine.

Please always remember

LBC: 100 Mkeys/s = 200 Maddresses/s
oclvanitygen: 270 Mkeys/s = 270 Maddresses/s (only compressed)

Rico

I think that if oclvanitygen computes 270 Maddress/s, that means that it computes only 135M of x-coordinates (x = coordinates of points of the curve that represent the public keys) and not even a single y-coordinate.
Then the strings: "02x" and "03x" produce 2 addresses ( 2 for each x):

"02x" --> compressed public key
"03x" --> compressed public key

Current LBC generator computes 100 Mkey/s, that means that it computes 100M of x-coordinates + 100M of y-coordinates, then

"04xy" --> uncompressed public key
"02 or 03x" --> compressed public key

Total: 200 Maddresses/s.

Potentially our generator could computes other 2 addresses (not in the same time) from the same x/y, because there are other 2 points related to the same x,y coordinates:

"04x(-y)" --> uncompressed public key
"03x / 02x" --> compressed public key

Note: sha256 should take half time if only applied to strings like "02x" or "03x" (only 256bit) respect of "04xy" (more than 512 bit).
That's why oclvanitygen seems faster than LBC.

Essentially the cost of compute an uncompressed public key is higher than that related to compressed key (because of y and because of sha256)

Just out of interest: what are your costs per day (or so)?

In the past hour we were 1107156445 keys/s
(at this speed we will have #51 in 2 days)

Rico

Speed is even higher right now ...

Countdown to #51 ...

got more Gkeys generated than the whole pool combined

Very nice.
Please always remember

LBC: 100 Mkeys/s = 200 Maddresses/s
oclvanitygen: 270 Mkeys/s = 270 Maddresses/s (only compressed)

edit:

theoretically, you could distribute the load to your GPUs 3x 10 (or 10+11+11) and let one do other mining stuff.
4 x 64% = ~ 256% -> 144% spare capacity so one full GPU for sure.

I thought about exactly such a configuration (4 x 1080, but Skylake-EX core to feed the GPUs, should come close to 200 Mkeys/s)

Rico

Yeah. But I'm not interested with mining. That's why I came here Cheesy

We will found bounty or giveaway in a few days.

First off, welcome in the top30. Your GPUauth has been delivered.

Thx a lot!

I will use my Radeon GPU as soon as a Windows client or a LBC-Appliance with Radeon GPU support is released.

Have a nice day,

Holy Sh!t - if you look at the "Notable Dates" section of https://lbc.cryptoguru.org/about
you'll see the pool needed about 4 months to crunch its first 100tn keys.

The more we are into #51 search space (only 270 MBlocks to go), the more nervous I get. #51 is a mean bitch for sure - but should we get to the end of the search space without a hit I will have to shoot myself.

On the other hand - that's how I felt with #49 too. Cheesy

what about https://www.nimbix.net/jarvice/ ?
Allegedly with Pascal GPU support:
"...Nimbix is the only public cloud provider featuring NVIDIA’s latest generation Pascal Tesla P100 GPUs with NVLink, a high-bandwidth, energy-efficient interconnect that allows data sharing at rates 5 to 12 times faster than the traditional PCIe interconnects...."

First off, welcome in the top30. Your GPUauth has been delivered.

Nimbix looks like similar business to the https://www.leadergpu.com/ link arulbero posted. I wasn't aware of all the "smaller" cloud providers (or let's say: hardware-on-demand) and with these offering newer GPU systems it is my hope that Amazon and Google will not take much longer to offer these too.

LBC doesn't need any fast interconnect between the GPUs it's perfectly parallelizable without any such inter-GPU communication, so NVlink is not a must.

ofc not ... lots and lots of CPU's ... no GPU for me Sad

Don't take it personally Wink

It's more like no (performant) client for K80. (yet)

I had a look if some cloud vendor offers any Maxwell (M60) or Pascal GPUs (P100). I'm pretty sure with these LBC would work and it would even mean a nice performance kick. Unfortunately so far only promises and plans:

https://blogs.nvidia.com/blog/2016/11/16/tesla-p100-on-google-cloud-platform/
observe how "now available" in the subject = "will be available" in the 1st line of the text

I checked today. Nada. Only K80 and only in some locations. Roll Eyes

I also am thinking about purchasing a dedicated 200 Mkeys/s machine...

Could you share with us some informations about how do you got this speed? Is it expensive?

This pool could reach a very high speed if it were more people able to use a lot of CPU like you do. Wink
