does a google docs exchange count?

Good question. Unfortunately, no, I'm referring to a full automated exchange, sorry Sad If you want to get a google docs exchange together though, I'll give you 75 BLC if its nice Smiley

To clear up some potential confusion, I didn't write the OpenCL miner, I paid smolen a bit to modify reaper to support blakecoin.

Closed beta (open to anyone who has some hardware not already covered by testers who currently applied) will be going out in a few hours (Let's say, target of 5PM forum time, so about 2.5 hours). After that, sometime Monday (probably monday afternoon for me, might be early Tuesday forum time) I'll gather all the data (best settings for GPUs, GPU speed, temps, etc.), put together an official launch thread. However, since I only funded the project and didn't write the miner myself, I won't be able to provide any new builds based on code changes, etc. unless they are fairly straight-forward. My hope is that the community will pick the software development up.

Here's some current stats:
7950: >2GH/s at a decent overclock
7970: >1.6GH/s at a decent overclock

Also, I'd like to note that, since the blakecoin algorithm (blake[8,10]) is pretty simple, it seems that GPUs spend a bit of time idle between each round, meaning that higher clock rates are stable. For example, my 7950s at 1100MHz are running great. They came stock at 960.

To make the math easy, at 10MH, the CPU will get (from test results) somewhere around 0.06 difficulty-one shares per minute, or around one difficulty-one share every 24.6666667 minutes. At a difficulty of 900, you need 900 difficulty-one shares. Therefore, it would take nearly 16 days to get a block at current difficulty with one of those CPUs.

At 10Mh/s it takes (2^32)/10000000 = 429 seconds (7.15 minutes) to scan the nonce range for a difficulty one share. Now my statistics knowledge is a bit rusty, but I reckon this should be the same as the long term average to find a share. So that gives 900 * 429 seconds = approx 4.5 days rather than 16 days, which chimes in rather better with my current experience of a roughly 2-4 blocks per day on around 89MHash/s.

Diff is now at 1168 (first time above 1000?), are the GPU's coming online already?

Ahh, appears my napkin math was wrong, never mind Tongue

From my observations, it seems that an average high-end processor (i7-3770k, AMD FX-8320, AMD FX-8350) gets around 10MH to 12MH.

To make the math easy, at 10MH, the CPU will get (from test results) somewhere around 0.06 difficulty-one shares per minute, or around one difficulty-one share every 24.6666667 minutes. At a difficulty of 900, you need 900 difficulty-one shares. Therefore, it would take nearly 16 days to get a block at current difficulty with one of those CPUs.


The OpenCL miner is coming soon, I want the launch to go real smooth, so if someone with one or more of the following cards can PM me so we can get performance statistics together and figure out optimal settings, that would be great:
-7990
-78xx
-7770
-6990
-6970
-6950
-68xx
-5970
-5850

Also, I'm gonna try to time the GPU miner release with some pool software from BlueDragon(747), but that is a huge job, so we'll see how timetables work out...
787  Alternate cryptocurrencies / Altcoin Discussion / Re: [BLC] Blakecoin giveaway! 2.5 BLC to everyone! (1/10 of single block) on: October 19, 2013, 03:13:33 AM
Sent to all above except esurance and Killa, for some reason blakecoin says those are invalid blakecoin addresses. Odd. Sad
788  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 19, 2013, 01:04:43 AM
Gonna try to release an OpenCL miner in the next 24-48 hours, keep your eyes peeled Smiley
789  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 18, 2013, 02:25:54 AM
Seems network is now syncing correctly, haven't had a fork in a while 8-)
790  Alternate cryptocurrencies / Altcoin Discussion / Re: [WTS] 1000 BLC for BTC / XPM on: October 16, 2013, 09:36:21 PM
Personally I'd price blakecoins a bit higher than OP priced them at, but perhaps I'm just using pipedream math.

I'm close to setting price 4+ BTC / 1000 BLC, due to its difficulty (soooo hard to find a block  Angry )

Yeah Sad

Figures people won't buy at > 4BTC/1000BLC, but I wouldn't want to sell under that either... Ah well, market is undeveloped.       
791  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 16, 2013, 09:30:35 PM
Good advice I use -t 7 for my i7 2600k

I will re look at the current budget I have set for Blakecoin and think about adding more server nodes over the next few weeks unless someone wants to volunteer any fixed IP nodes for the network?

I got quite a few blocks in the early days, but since the 12th, haven't seen anything. Only got one block on the 12th. Sad
794  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 15, 2013, 12:42:16 AM
Well after 6 days (almost 7 days now) mining with 3 x 8 core cpu's i give up with 0,0000000000 blocks found

My i7 3770k + amd fx8320 and my E5-2690 have not found 1 accepted single block

Yes i got many unconfirmed but all of them disappeared

Its ammazing that i see almost every 10 minutes a new block being found, however non are being found by anyone other then those special people getting them all

I still have the enormous amount of 12.5 coins which i got from the give aways

I try not to think how much the price in electra it has cost me, but it will not be pretty

Ouch Sad Seems like someone has a GPU miner or a ridiculous amount of cloud power.
795  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 14, 2013, 01:08:54 AM
I wonder how much mtrlt would charge to do a Blakecoin version of reaper....
796  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 13, 2013, 08:28:01 PM
0.8.6 seems to be working great.

On another note... difficulty above equivalent 120000 for pre-0.8.6 difficulty calculation. :O
797  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BLC] Blakecoin fast blake-256 Alt Coin for CPU/GPU/FPGA on: October 11, 2013, 10:52:16 AM
Wow, difficulty is approaching 90,000 :O

How hard do you guys think it would be to make reaper do blake? Interestingly enough, the reaper source code has a file for blake-512, but we need 256.... Sad

that's just the c code for blake-512 the stuff that runs on the GPU is the .cl files, not had time to work on the GPU miner but I do have blake-256 in opencl soon as I get p2pool working and take a look at the pool code for a few operators I will be working on the GPU miner  Cool


Ahh, right, silly me. Can't believe I forgot to look at instructions Tongue

Have you seen https://github.com/wfr/clblake/tree/master/src?
798  Alternate cryptocurrencies / Altcoin Discussion / Re: [WTS] 800 BLC for BTC / XPM on: October 11, 2013, 02:07:10 AM
Prices here seem slightly low, given difficulty explosion, value will probably go up fairly quickly. At any rate, sgrunger--want to sell me 500 BLC?

......

one thread per core. 3*24-core machines, 2*8-core machines (all - Xeon servers)

That's some pretty serious hardware you have got there sir. Is that a box with 3xcpus each with 24 cores or are you running 5 boxes with a total of 88 cores?
Impressive setup either way!

5 boxes (24 = 2 CPUs with 12 cores each)
some time ago I had total 198 cores, but now only that 88 left  Grin

Are you renting those, or are they part of some unused infrastructure you have access to?

Unused infrastructure. Sometimes some machines become 'used' and I lose some of hashpower, but it is still rather good for CPU coins.

edited: difficulty 65K  Shocked

How many blocks are you getting with the new difficulty?

Oh, and to OP: tried on i5-2500k (no OC) and got around 8300-8700 kH/s Smiley
