You don't get paid twice for doing the same work for the same employer just because you send them your bill to two different locations.
Might work with unorganized employers but not with BURST

The GPU mode is still kind of buggy on my graphic card (an old GeForce 9300M GS), don't know the exact reason yet. Sometimes it works, sometimes not. I will try to fix this issue tomorrow. I would never say never, but I am quite skeptical about the nonce computation ever being modified for major speed gains on current GPUs. It requires each thread to crawl over every part of a 256k buffer while computing shabal hashes for all of it, and the cores on top-end GPUs only contain 64kb of memory. I can't see any way to avoid a huge amount memory bandwidth. This is a different problem than for scrypt (where you can trade the memory for extra computation), in that it actually requires access to the memory, or perhaps some fast way to find shabal preimages. Well only the last hash crawls over the whole thing. The earlier ones have a much lower cap of what it needs to hash, and that can be kept in local memory.

How long would 4TB take to plot on a last gen i7 mobile? Anyone know how many nonces/second and how long it would take? How could I calculate this?
Don't wanna waste my time.

You're probably looking at somewhere between 4 and 5 days, depending on how good of a mobile i7 you have.

Got about 3.4 TB I'm was able to get 4K BURST per day so at current rate of 0.00000430 BTC will be able to get 0.01728 BTC per day. Still profitable coin I'm ever mined. Will buy more TB soon.

Not sure about your specific processor, but my 4 core AMD Phenom II X4 965 Black Edition and 4GB RAM is plotting around 2400 nonces/minute. Calculating it out, that's about 4.3 days to fully plot 4TB.

Currently I am generating plots in 2GB files at a time while I am giving this a go. One q.
As I generate new plot files, I know I need to move them to my v2 folder for pooled mining. If I move new plot files in, do I need to restart my miner -- or will it automatically pick up the new plot files?

Hi everyone, After many hours of setup I finally made it. I have a 1Tb generation in progress and 3x100Gb already finished. I would like to test the V2 pool but I haven't any BURST for now. Could someone send me 1 BURST to test it please ? Here is my address : BURST-YA29-QCEW-QXC3-BKXDL. Regarding the plot generation, I found an OpenCL implementation of Shabal ( https://github.com/aznboy84/X15GPU/blob/master/kernel/shabal.cl) that could be used to make a GPU version of the generator. I will try to work on it when I have some free time. Regards Hi everyone, As promised I have been working on a GPU plot generator on the last few days. I made a little program built on top of OpenCL, and it seems to work pretty well in CPU mode. Unfortunately, I can't test the GPU mode as it requires a very powerfull graphic card (with at least 46kB private memory per compute unit, because the algorithm needs at least 4096*64 static bytes to store an entire plot). Here is a preview you can test for now : gpuPlotGenerator-src-1.0.0.7z : https://mega.co.nz/#!bcF2yKKL!3Ud86GaibgvwBehoxkbO4UNdiBgsaixRx7ksHrgNbDI gpuPlotGenerator-bin-win-x86-1.0.0.7z : https://mega.co.nz/#!HJsziTCK!UmAMoEHQ3z34R4RsXoIkYo9rYd4LnFtO_pw-R4KObJs I will build another release in the end of the day with some minor improvements (threads per compute unit selection, output of OpenCL error codes, improvement of the Makefile to generate the distribution directly). I will also try to figure out another mean to dispatch the work between the GPU threads to reduce the amount of private memory needed by the program. For the windows people, you can use the binary version directly. For the linux people, just download the source archive, make sure to modify the OpenCL library and lib path in the makefile (and maybe the executable name), and build the project via "make". To run the program, you need the "kernel" and the "plots" directories beside the executable. The executable usage is : ./gpuPlotGenerator <address> <start nonce> <nonces> <stagger size> The parameters are the same as the original plot generator, without the threads number. If you find bugs or if you want some new features, let me now. If you want to support me, here are my Bitcoin and Burst addresses : Bitcoin: 138gMBhCrNkbaiTCmUhP9HLU9xwn5QKZgD Burst: BURST-YA29-QCEW-QXC3-BKXDL Regards Unfortunately, I can't test the GPU mode as it requires a very powerfull graphic card (with at least 46kB private memory per compute unit, because the algorithm needs at least 4096*64 static bytes to store an entire plot).
It's nice to see someone else working on this, since I seem to have failed in it. Private memory is actually part of global on AMD cards, so storing it in private isn't any better than just using global for everything; it's local that needs to aimed for for the massive speedup. No AMD cards have more than 64KB local per workgroup, which makes storing it all in local impossible however. I haven't tried your implementation yet, but on my own first attempt, I also used global on everything also, and the result was faster than the java plotter, but slower than dcct's c plotter. My 2nd attempt used a 32KB local buffer I rotated through for storing the currently being hashed stuff, however I couldn't figure out how to get it copied also to global fast enough, and the local -> global copy killed the performance. You might be interested in those kernels here: https://bitcointalk.org/index.php?topic=731923.msg8695829#msg8695829Thanks, I will look at your kernels to see if I can find a better solution. Here is the new version. I reduced the amount of memory used from 40KB to about 1KB per unit. The only drawback is that it requires twice the global memory as before. I will search a mean to reduce this overhead later. In CPU mode, it all goes pretty well (when no graphic card is detected). The GPU mode is still kind of buggy on my graphic card (an old GeForce 9300M GS), don't know the exact reason yet. Sometimes it works, sometimes not. I will try to fix this issue tomorrow. Here are the files : gpuPlotGenerator-src-1.1.0.7z : https://mega.co.nz/#!iYFWAL5B!BvtmRQ5qGq4gGwjDglFNtDtNIX4LDaUvATBtClBdTlQ gpuPlotGenerator-bin-win-x86-1.1.0.7z : https://mega.co.nz/#!aBVGBBQD!tBsRtb8VrHR12_anrFTrl41U0fPQu_OqFnxyi5nCyBY For the linux users, the Makefile has a new target named "dist" that builds and copy/paste all the necessary files to the "bin" directory. The executable usage is : ./gpuPlotGenerator <path> <address> <start nonce> <nonces> <stagger size> <threads> <path> : the path to the plots directory <threads> : number of parrallel threads for each work group So the usage would be like this: "D:/gpuPlotGenerator <numerical_account_address> 0 819200 4096 <cpu/gpu_threads?>" Is that format correct? Is the thread count need for gpu plotting(Point out in bold)? What's the nonce/minute rate?

Is there any way to generate plot files locally using an EC2 instance?
For example, I have a local 4TB storage but I want to plot in the cloud via streaming the files. Does something like this exist? I DON'T want to store the files in EBS since that will cost me a ton. Or is downloading from EBS and then wiping the only way? Does S3 charge for the whole month on the spot or is it hourly/daily/averaged?

I got a new hard drive in the mail today. This compy is already busy plotting, so I'm gonna use a different comp to start plotting on. Can I still just copy over the pool PocMiner, adjust the plot ranges, and then generate/mine on another computer? Will this still connect to the v2 pool with the same account?

I know you can do this from the same computer, but not sure about different computers (in the case that you're using external USB hard drives). Just remember to change the plot ranges...they're not hard drive dependent, they're account dependent.

You'd be charged for the bandwidth to transfer large amounts of data from your EC2 to a local drive.

I ran the tool at https://bchain.info/BURST/tools/overlap and this was the result: 3104997 nonces overlap (758 GB) 6744997 nonces total (1646 GB) 6742 disk seeks per Scoop (53.9 seconds @ 8ms) I don't know how I did this because I thought that my math was good. Anyway it says I have 1646 GB total on a drive that had 888 GB free when I started generating plots.. WTF does that mean? I have other drives that are reporting overlaps too. Should I wipe it out and start new? Thanks Signed The Retard. They are beeing added up: 758 + 888 = 1646 Whats shown is correct, no need to start over. Well that is a relief but I do not understand the math. Before I started generating plots I only had 888 GB free on the drive. I had to reboot my computers while plotting so have multiple files. So why the 1646 GB total for 888 GB of space? I am confused. You restarted while your computer was still plotting, this is the reason. The file NAME will reflect the full plot range you started plotting, even if you didn't finish plotting it. If you know the last plot that was actually reported as plotted before you restarted, you will have to rename the file to that nonce instead. ...or you could start over. But renaming the file (if you know the last nonce it actually contains) would be more efficient than re-plotting everything. I will leave it because I am not sure now. I used the advice of people on here and started plotting again. I do not think that there are overlaps or 1 nonce at the most. Thanks for putting my mind at ease. The tool on the web site only analyzes the file names, not the files themselves. So, if one of your plot files was incomplete but you didn't rename it, then the tool will think it overlaps when it may not.

Guys i'm trying to hook up another hdd too plot it and mine from it, my first one was like this #AccounId#_0_1700000_7000 which is 425gb, what should my next start and end with so as to not creatie overlapping nonces?? I appreciate the help. Newbie here.
start your next one at 1700000 use https://bchain.info/BURST/tools/overlapWhat should it end with? Because when i double this amount it says 5100000 nonces total (1245 GB) when it should only be about 850gb.. #AccounId#_0_1700000_7000 #AccounId#_1700000_3400000_7000 Also can i plot that hdd to the same account ID as the other one? You don't want to double the amount - that number is "how many nonces do I want to generate" not "what should the last nonce number be". So if you want another ~425 GB plotfile, use #AccountId# 1700000 1700000 7000 <ProcThreads> Format is: <AccountID> <StartingNonce> <NumberOfNoncesToCreate> <StaggerSize> <NumberOfProcessorThreadsToUse>
