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

[HoldTheLine]

is there a merge utility for windows as of yet? what I like about thus coin is as your plotting and mining you see a noticable increase for example yesterday 250 bursts per 12 hr cycle of personal payouts. today after 25% more hdd 0lotted 500 burst in 2 hrs :-)

Hi,


if anyone can help me out, i got one of this nas http://www.seagate.com/external-hard-drives/network-storage/business/blackarmor-nas-440/

with 8tb, im just wondering if i could use it for mining?


Thanks in advance.

yes you can... map the share in windows as a mapped drive and good luck

Careful with the merge tool - if your plots were incomplete (i.e. you had to kill the plot generator before it completed the scheduled plot) and you don't rename the files properly to reflect their actual size, the merge tool will DELETE your existing plot files! Thankfully I only lost ~200 GB of plots...

EDIT: I should have said, careful with the .bat file commands that are suggested, since it includes a line that deletes the input files (even if there was no new output file).

lol i just lost a 1.5 tb file XD

Ouch! thats gotta be what 2 days work?

[unsoindovo]

LOL i just discovered that you can simply copy-paste your plot and change the name of the start nonce, this mean no more plotting

they don't overlap lmao

maybe someone can be of interest.
Calculate the correct START and END point to not overlap the plots!

yes. at first start just using 16gb and keeps rising until fills up all memory. maybe im doing something wrong.

when i open 6 miner on 32gb machine memory usage at start 16gb and keeps rising and later fills up all memory. stagger size is 1024. total capacity is 6 tb.

how can i configure windows machine or plots to use less memory?

The actual mining does not consume much memory. Plotting yes.
from the command "run_generate.bat 987654567890987612 0 80000 8000 7" that you are using to start plotting, 8000 represents the stagger size. The number of nonces to generate in a stack (stagger). And one nonce has 256 Kb of space/memory consumed/used
So, if you lower that you will lower the amount of memory needed to plot.

So your saying that you only start the miners and they start using 32 Gb of RAM?

There are 2 aspects to this.

1. edit your mine.bat's -Xmx parameter. Xmx sets the max memory each JVM instance is allowed.

2. Windows 7's prefetching has a tendency to attempt to load and keep in memory large amounts of plot data after it sees you keep reading the same files repeatedly. Ironically it sometimes can try to preload so much that there isn't enough memory left for the miner to actually function, causing instability. If you start mining, see the ram usage increasing, then close the miners and see that most of the memory has not been released, this is likely your issue. I had 2 machines that started fine, then started having stability issues like this, and disabling prefetching fixed both of them immediately. To do this, open the services manager, stop and disable superfetching, then open regedit, go to HKLM/system/currentcontrolset/control/sessionmanager/memory management/prefetchparameters, and set enable prefetch, and enable superfetch to 0. Then reboot

i tried this, but it doesn't work, my generated plot aren't on the same HD where windows is installed, maybe this is why it doesn't work?

My v2 pool going down for update for a minute in a few minutes. There was a problem where is could double-pay people for blocks under a particular situation. I'll cover the 10k coins it overpaid.

Also, we have too high a portion of the network hashrate on this pool. This one pool got all these blocks earlier:
9868
9872
9874
9876
9877
9881
9882
9883
9885
9886
9887
9888
9889

No pool should be getting 5 blocks in a row...

Can we do something to optimize deadline?

I feel that my deadline are bigger than yesterday

[coinits]

About how long does it take to generate plots?

40..60Gb/hr on a windows box

Any faster on linux?

~2x

Linux rules 

OMG, I just had THE worst time with linux because of the prospect of plotting ~2x faster.

So, here's how it went:
Was plotting around 3200 nonces/minute on Windows 7 (4 cores)
Decided to try my hand at Ubuntu...
Downloaded an image, burned it, booted it, installed it to a spare drive
Got Java installed and was feeling very accomplished...

Tried to figured out how to use dcct's plot generator (which failed miserably).
Posts in the forum stated that you need to "make" the plot app...
Much Googling led me to needing additional build tools needing to be installed to be able to "make" the program, which I don't see mentioned anywhere (sudo apt-get install build-essential gcc).
Made the app by doing a CD to the location of dcct's plot generator I downloaded, then issued the "make" command...
...and I get a wall of error text spitting out.
Much more Googling, led me to issue a "uname -a" command only to find out that my build was "i686" (which is apparently 32-bit only) instead of the required x86_64 (which is 64-bit).
*sigh*
all that time wasted...

Downloaded a new Ubuntu image, this time I made sure it was 64bit
Booted the new image and go to install, but something is strange...
The license agreement was missing data, Mouse would randomly stop working and I had ZERO network connectivity
{Completely baffled why the 32bit Ubuntu had no issues, but 64bit is FUBARd}
*Much more Googling ensues*
Tried a bunch of suggested things for networking, tried a wifi dongle... even manual settings. zero connectivity.
*MUCH Much more Googling ensues*
Found a post stating that "IOMMU" (whatever the heck that is) likely needs to be enabled in BIOS.
Found & enabled "IOMMU" in my BIOS
HOLY COW! The 64bit version now has NO ISSUES! Amazing!
{Now feeling super duper accomplished!}

I repeat all the original steps (installing java, build tools, etc)
I go to "make" dcct's plot generator again, and it fails... *sigh*
*more Googling reveals that it's because the secodary drive (my plot drive) is in read only mode
{WTF?! why would I NOT want to write to it?!}
*Googling is getting REALLY old at this point*
Finally found information on how to remount the drive as writable...
"make" the plot generator (and it finally worked this time!)
issued the commands to start plot generation....
and it is now plotting!!!!
{Much excitement!}
.......... SLOWER THAN WINDOWS! (@ 2400 nonces/minute)
*sigh*

TL;DR - Wasted the better part of an entire day trying to get "~2x faster plotting" working by using Linux instead of Windows. Ended up being much more work than it was worth, because the Linux install is plotting SLOWER than Windows.
Windows: ~3200 nonces/minute (4 cores)
Linux: ~2400 nonces/minute (4 cores)

It's your opinion that Linux rules, but that has not been my experience lately

Linux has always sucked because it has never been easy to run which will send the Linus lovers bashing me.

This is not good timing and will affect price. Please rectify this ASAP. Split your pool into multiple pools if need be.

Do you have the source for your v2 pool server posted anywhere? Making it easy for others to get pools up and running will help spread out the mining power.

[gigica viteazu`]

hey guys.is there still that program that calculate your plot size before starting them

number of nonces * 256 / 1.000.000 = size in Gb

PlotSize (GB) = NumberOfNonces / 4096
NumberOfNonces = PlotSize (GB) * 4096

your formula gives a rough estimation, the one posted by me it`s more... exact (file on disk size).

1**********************9_60000000_40960_40960 - 10Gb (your version) - 10.485Gb (mine)

1GB is 1024*1024 kB. Your formula is wrong. Just check any one plotfile.

are you sure ?

[alphateam]

Got 5400 Nonces with core i7 3930k (not oc)

6 cores at 3.2 GHz doing 5400 n/m. It`s 213.3M cycles per nonce (on 1 core)
Boost clock is 3.8GHz - so get 253.3M cycles per nonce

My I5-2500K (no OC too):
base clock (3.3G): 204.1M cycles per nonce
boost clock (3.7G): 228.9M cycles per nonce

Just love math, LOL  

How are you guys getting the n/m? Calculating it manually or does it show up in the linux version of the plotter?

I see it in the c++ windows plotter

Where is that?

Sorry i try to find the post, but don't found it

[Amph]

what's the matter? you can call your start nonce, 0,1,2,3,4,5,6, and will be ok

[paduser]

If I generatet my plots with the pc could I use a raspberry pi to mine with this plots? Should I use the normal poolminer or a special one?

And does someone ever try to use a PI for plots generating?

bash.
Seriously, you are right. But with a little time and patience you can do great things. I am not a Linux guy either. But seeing that it was faster to work with and most tools came for L, I ditched Windows.
In my profession I had to adapt to everything

[alphateam]

Does something can cause higher deadline then usually?

[gigica viteazu`]

And does someone ever try to use a PI for plots generating?

mining works on rPI but it`s useless to try to plot on it.

Thx so I keep generating on my windows.

[Sglasio]

Guy's.... cant someone tell me...

I generate plots with 409600 size and 1024 stagger. (107Gb appr.)
with 4500 nonces in minute (60Gb/h appr.) ~1.5Hr at 1 plot
But merge process (merge by dcct) take very very more time.
It's normal?

After merge, my plot has 409600 stagger! (100 scoop)
Before 1024 (400 scoop)

[n4ru]

Does anyone have experience plotting in the cloud? What's the most efficient way to do it using something like Amazon EC2? I have some free credit that I'd like to use. If anyone could help me out shoot me a PM.

[Sglasio]

I like to share a little tool I wrote to increase stagger size for already finished plots. No more 8191 limit!

Its simple C code - for linux only - its short, so check & compile yourself.

https://bchain.info/merge.c

It does not hold everything in memory but seeks on disk to get the scoops.

version for Windows - https://www.dropbox .com/s/g4xs48y0505lu0u/merge.exe?dl=0

someone test? this is working fine?
