[ANN][BURST] Burst | Efficient HDD Mining | New 1.2.3 Fork block 92000

There is definitely some optimizations that could benefit Blagos miner. My experience is that I need to use a lower cache size than what ought to be optimal. Optimally, the miner should read all the data it needs from a file in one go, and do it's thing. That would limit the IO seeks to 2 per plotfile. But if I set the cache size such that it should be able to read everything the CPU will visually idle while it's trying to find the best offset. However if I lower it to 131072, it seems to keep the CPU at 100% utilization.

That said, I still have great success with optimizing. My 16TB took ~110s unoptimized, and are now running in ~80s, great improvement.

So after playing around and comparing Optimized Vs Non-optimized plots with the J6 optimizer, it appears as though non-optimized plots are faster. They however consume more memory when being mined (optimized plots have almost no memory usage). The speed difference is negligible, optimized is 10~ seconds slower, seemingly regardless of the number of drives I have attached.

I'm not exactly certain why this is, especially when everyone is saying they're faster. I even used a faster processor and Blagos miner was not operating at 100% usage. To that end, it appears that Blagos can only split threads down so much and it was effectively limited by one logical processor... at which point it would be faster if I had a higher frequency processor (single threaded performance becomes a bottleneck).

These are 4.54TB plots on 5TB 5,900RPM drives with 8192 stagger. They're hooked up via SATA 3 and I'm running W8.1 x64. The fastest I could hash one 5TB drive was 47s, it was non-optimized. A optimized one took 51s.

I really don't know why you'd want to optimize, unless you have extremely slow drives or almost no memory. Even on my pokey 5,900RPM drives, the bottleneck is definitely the processor (which makes a GPU assisted miner all the more desirable). The amount of time it takes to optimize and risk breaking your plots doesn't seem worth it.

Although I haven't played around with it, I would theorize a higher stagger size would actually make mining faster (if you have 16, 32, or 64GB of memory). These results may be because of how large my plots are comparatively to other people who are using much smaller drives.

I've been testing this over the last week or so and this has been tested across multiple systems. A A4-4000, G3220, and a AMD x4 640 (which is what I'm currently using). I tested in single drive configurations and multiple drive configurations (up to five drives). The results have been retested too, at no point in time were the drives actually the bottleneck in any of my tests. Maybe I just don't have a fast enough processor and after a certain threshold a non-optimized drive becomes worse then a optimized one.

In order to surpass a certain threshold it seems as though you need an extremely fast single threaded processor for best case mining. A i7, overclocked is better. Hyperthreading will help when you have more then four drives, although I also suspect a eight core FX would perform well when you have more then eight drives as AMD modules work quite well in multithreaded workloads.

Thanks, how do you know if everything is functioning properly? I think I got everything working, but I'm not certain whether or not it's really 'working' so to speak. There is little to no documentation for the miner so I don't have any idea what any of the dialogue or options actually mean.

Like what is: dl sdl cdl ss rs?

How often does the mining 'phase' happen?

Every new block (~4 min)

How do you know if you found a block mining solo?

You got burst in the wallet

How do you know how long it took to process the last deadline and what the deadline is (I'm using blagos)?

see stat-log.csv  (ID, #block, baseTarget, best_Deadline)

What is the initial 'mine' that happens when you start the miner up, where the percentage in the bottom left counts up?

percentage of reading of plots

What is optimizing people talk about and how do you do it? What does it mean?

merge the plots, defrag HDDs

Hey Blago, what processor are you using for the above screenshot, are all the drives optimized, and how much memory do you have? Also what interfaces are being used for these drives and what drives are these? Are these all 7200RPMs?

There is definitely some optimizations that could benefit Blagos miner. My experience is that I need to use a lower cache size than what ought to be optimal. Optimally, the miner should read all the data it needs from a file in one go, and do it's thing. That would limit the IO seeks to 2 per plotfile.

That said, I still have great success with optimizing. My 16TB took ~110s unoptimized, and are now running in ~80s, great improvement.

Hmmm, what sort of drives are you using? I never saw an improvement from optimizing my drives, I'm using the J6 optimizer as well (not Blagos). The drives I'm using should be very fast sequentially, but suck as far as seeks go (slower spindle = longer seeks, higher density = faster sequential).

I actually seem to be running into a absolute lowest mine time of ~50s for one of my drives. Although I'll be testing more later tonight on my desktop CPU (4690k). I OC'd my x4 640 an additional 25% and it didn't move that time at all, which I'm starting to think Blagos is part of the bottleneck (it can only process so fast regardless of the rest of the system).

When looking at the drives in resource monitor they aren't transferring that much data. The GPU plotter wrote to them about 3x faster doing a 8192 stagger buffer, which I assume is similar in nature to when they're getting mine

Why 131072 too? Why not 100000?


Some more testing, it looks like my drives are not the limitation. Looking at random transfers in HD Tune using random access, they're about 4x higher then the transfer speed I'm getting with Blagos at the same block size >64K. That is a worst case scenario as well, which shouldn't be representative of a optimized disk (which is supposedly mainly sequential).

Hey,

The Crowdfund case is here and ready to be used to fund your projects and ideas. The rules are simple.
You define a name, a description, the total duration of the crowdfunding and the total amount you need to gather. After the duration you have set, the AT checks the total amount gathered and if is greater than the one you have asked, the total amount is sent back to the ATs creators account. If the project is not successfully funded then refunds all the participants the amount they have sent minus the fees the AT needs for processing ( approx. 7 bursts ).

After the crowdfund case is done, the AT acts as a donation address, where any amount sent to the AT goes to the creator of the AT.

As in the lottery case I created a html file for making things easier for anyone interested in creating his project or help funding the project. If you want to use the html file then copy it under html/ui/ directory.
The resulting html looks like that:


You can find the corresponding html here: http://burstcoin.info/d/cf
and the assembly code of the CF case here: http://pastebin.com/09j994Yc

I found a bug. The wallet mixes up the lotteries and the crowdfunds. On one pc I can see the lotteries and the crowdfunds in the atcrowdfund.html and on the other computer I see both lotteries and crowdfunds in the atlotteries.html.

i have read some post ago,
about AT...
i have read there are a lottery game, already implemented...
maybe, there are any possibility to see in future,
other kind of gambling

I am aware of tha bug. When I made the lottery html I forgot to filter the ATs based on the name or description. We have discuss it with burstdev and we said we need to put one more field (tags) when creating the AT. This way the filtering of the ATs will be easier

Sure, we were in discussions about an AT dice game. It would work without problems, the only drawback would be the wait time, as you'd need to wait for quite some blocks before you'd get your results and/or payment.

i think thi is possible..
after all,
as you rightly point out,
there is already a lottery game!
and probably there will be other games that you can do ...

i think vbcs could help the community to inplement this type of games..

The name should not contain spaces

I tried it again without spaces - same error. Are there other limitations? Do I need anything else except 1.2.2 wallet and atcrowdfund.html? What is the fee needed - there are just 2 burst there (BURST-RUL4-HV8X-C2US-79AAU)?

There is a limitation on the total size the name can be, but i dont recall atm the exact number (maybe 30 chars). Maybe that is th reason you are getting rejection. Can you try with a shorter name instead?

Update to this, with a 4690k I got it down to 32s, but the drive still wasn't being maxed out.

-[ANNOUNCEMENT]-

pool at http://burst.ga is currently being worked on. There will be downtime. The pool is going to the new pool code. I will post when complete, bear with us during the changeover process. Thanks!


Also, please stay tuned for the Asset announcement from ByteEnterprises, and how you can get involved. Thanks!


EDIT : Nevermind, due to a situation, the swap is going to be moved to tomorrow. So will the asset announcement. Thank you for your understanding!

[q327K091]

nice , already made money yesterday 201 sat Today 223 . I absorbed lot of coins yesterday ... of course I ain't selling not as much as even 1 satoshi of BURST

 

who the heck was selling yesterday at such low price.. I know folks picked it up even at 188... yo whoever you are you just like to use exchanges thrill of placing an order must be

if I see another wave to the ground like that I am scooping this time if I can over 1 million if allowed. network capacity ain't stopping , exchange trading exceeds value of increasing drive capacity

so if you want to unload BURST please ping me.. but I don't do escrow.. just give me heads up before exchange play.. same thing 200 sat and < I am ok with

 

speak soon

sorry if naive' q, need this to cordinate my trading activity, does anyone know exact nature and schedule of block reward reductions into the future , like a time table ? thanks in advance, what I really would like to have is network capacity projection, but that is next to impossible...

thanks so much... great.. also will allow solid distribution world wide even with lower capacity drives in developing countries.. thought reduction was more aggressive.. it is not ... very very cool, and developing countries are high on electrical costs.. so there you go with decentralization,,, granted China could build a warehouse and stack it with high capacity SCSI's and begin race war in this space as well.. if it happens you all should get chunk of BURST as soon as you can at Tera and sat (on exchanges) as its allowed right now

checking bittrex action again... very interesting trading pattern.. like 12 BTC volume Today.. lots of 250K sold at 200 sat.. and rebought etc

believe "asset" territory is also untapped to a degree as well.. although NXT spined off so many that is hard for people to dissect although it is all very valuable long term

you got basically two coins that are "decentralization" friendly it is BURST and MAGI , both were actually presented together at a conference and it makes sense

bought Magi when BURST was at 300 satoshi and in reverse bought BURST when MAGI was 4908 sat.. both are excellent investments long term in my opinion . they, developers should consider "talking to" Supernet developers and close that bridge as well.. anyways..

> 200K BURST lots are gone, so now you have bots playing arbitrage in minuscule amounts, lucky thee who scooped these lots at 200 sat range.. there is one left but < 1/4 40K at 187 sat

thinking thinking.. need to transfer that BTC amount.. that's around 0.07 BTC which is nothing, gone.. next level is 204 and 207 sat...

Here is a 4 year chart. In about 41 months(3 years 5 months) we will be down to just 852 burst / block...about 306k / day

funny attempt to depress value at bittrex, at 497 coins , let me see at least 200K and it needs to fall below 200 sat.. thanks

200-250 burst

correct.. i have about 12TB... and i do about 2600 burst/day...
this is just an average.. on 10PB newtwork size...
and this parameter it is really unstable...
a day you can mine 5000burst and another you can mine 1500burst

the same here.. anyways.. do let know of any dump below 200 via BTC PM and will take coins from you
