Cool Story Bro. 

Glad you enjoyed it. Figured I'd share with the community... and tell it at parties and whatnot.

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

Cool Story Bro. 

i guess java showing 3200 nonces/minute is the fail.
have you compared the filesize and time needed for creation?
i only plot on linux and i still get 2x faster plots compared on time needed to create the files.

[alphateam]

burst is dead, i lost so much money on this

You should do a stand up comedy act so we can boo you.

so we are the only ones to have the mem issue?

No same problem for me, with two disk, one miner close automatically after a few times (sometimes 10min sometime 2 hours). For the moment, the only thing i found to let it run, it's to convert the .bat in a .exe and launch an app that allow to automatically restart the exe when crash....

Apparently, the biggest the disk his, more often the problem appear.

Could you please share how to convert to ext and use an app to automatically restart the exe when crash. I am having this issues frequently in one system!

To convert your bat on exe, use the free software "bat to exe converter", then to relaunch your exe when crash, use "knas restarter" free too.

On wich pool you are?

[fabula]

So. Why my xeon with 8 core male just 1000 nonché a minute? I nave set 8 in generate.

[smokim87]

do i have to generate the plot in one go...can i generate 10 plots of 100 GB instead of single 1 Tb ..because it takes lot of time to generate a single one and if something happens in between and it closes..all time is wasted..

I think I read in the readme file included in the miner, the bigger the plot the less stress when mining starts but I think you can plot 100GB at a time just need to set your nonce after every plot is done.

So first plot 0 400,000
    Second plot: 400,000 800,000
    Third plot:    800,000 1,200,000

and so on. 800,000=200GB.

You plot numbers would actually be this:
{WalletNumber} 0 400000 {stagger} {cores}
{WalletNumber} 400000 400000 {stagger} {cores}
{WalletNumber} 800000 400000 {stagger} {cores}
{WalletNumber} 1200000 400000 {stagger} {cores}

ex:
Plot1: 11111222223333344444 0 400000 5000
Plot2: 11111222223333344444 400000 400000 5000
Plot3: 11111222223333344444 800000 400000 5000
Plot4: 11111222223333344444 1200000 400000 5000
Plot5: 11111222223333344444 1600000 400000 5000
...and so on (Each of the above plots is ~100GB)

shouldn't plot2 start from 405000? since 400,000 was already plotted?

Also just wondering, how do you calculate nonce/min? I got mine set a 1000 but its not doing 1000 per minute takes a couple of minutes for a 1000. How do you guys know which nonce to set? Trial and error? or just set it as high as possible?

Thanks.

i only plot on linux and i still get 2x faster plots compared on time needed to create the files.

I'm just going off of the displayed nonces/minute.
The filesize on Windows appears to remain at 0kb (only actually displays the size if I kill the plotting, strange... but it appears to be plotting just fine)
I haven't sat down and actually timed linux or windows, but they seemed about the same (to me at least)

Right now I have the Dual Xeon (8cores on Windows) plotting a 2TB file and my AMD Phenom II (4cores on Linux) Plotting a 4TB file... we will see who wins

Watched the file size growing on the Linux (4core) box and it is growing at ~0.65GB/minute...
~0.65GB/minute * 60 = 39GB/hour
4000 / 39 = 102 hours for 4TB
102 hours = 4.25/days

Yeah, this may take a while

i'm at 4500 nonces/minute on windows with the x2 speed miner and i5 4670k(4400 oc)

just saying

how to merge all the plots in just one?

[vaxman]

For anyone who wants to get into mining seriously - quit thinking about SATA ports and USB enclosures and crap and start thinking real hardware.

http://unixsurplus.com/product/sgi-3u-media-server-storage-16-hd-bay-sas-sata-ssd-san-array-35-nas-jbod-good
less than $200, comes with 16 drive sleds and supports SATA disks.
All you need is a external SAS hba, which runs you less than a hundred bucks on ebay.

only problem is that these are 3GBit SAS-Expanders inside, most of which only support  2 TB SATA-targets.
That would limit you to 16x2TB=32 TB (29,1 TiB) per enclosure, tying you to the (price wise) unattractive 2 TB disks.

One other thing to remember is that you need to read 1/4096 of the capacity per block. And you want that to finish in less than 240 seconds, as most of the blocks finish much earlier than 240 seconds. So, to mine one fully populated enclosure you'd have to read 29,1 TiB/4096/120 seconds = 64 MiB/sec.

On my 3,2 GHz Box a single (linux-, java-based) Miner thread read in about 14,5 MiB/s, so you'd need 4 cores per enclosure.

But if you have lots of older disks "lying around", this is a very cheap way to connect them.
Just my 2ct.

why you need to merge?

the amount of reads will be the same!

3880 n/m on i5-2500k (skock 3.3)

Merge files in Windows (1,2,3 into one file 123): copy file1 /B + file2 /B + File3 /B File123 /B
All merging files must be with the same stagger size.

Why? You may do plotting 1024_1024 and then merge it to 1M_1M 4example.

apparently my mem don't go up if i use only one plot(i created 10)

[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)

Guess that means I get to read back through the last ~20 pages to see what I missed...
I really with OP would update the first post with new information more often.

[taaku]

can i use the generated plots on multiple computers with same wallet...will be mining on pool...
