21  Alternate cryptocurrencies / Altcoin Discussion / Re: [XPM] Working on a GPU miner for Primecoin, new thread :) on: September 02, 2013, 05:32:11 PM
I'm getting "The procedure entry point clEnqueueFillBuffer could not be located in the dynamic link library" and crash. Win8 x64 & GTX 560

I was away for the past week and will look into it again this week. Yes, it's just a hobby project and it got bigger than I expected. Currently, I'm the only one working on this, so if someone wants to chip in and help (programming), send me a PM.

Status:

I will push my lastest changes soon, I have updated my code basis to hp-9 and I implemented a fast big num small prime trial division for the GPU. Depending on the settings, this can filter out 10-90% of all candidates. The CPU than computes the fermat tests on the remaining candidates. I was under the impression that the sieve would already filter out all chains versus small primes, but apparently the high performance client still filters out some candidates with trial divisions and does this before doing fermat tests.

If a fast fermat test for the GPU surfaces, than filtering+fermat tests could be chained directly on the GPU to give a better speed up.

To clarify: I didn't push my changes because I still have a silly bug somewhere, so that apparently not all prime divisors are found. But doing more prime division tests than what the high performance client does by default yields already better speed ups directly on the CPU.

Thanks for the update and keep up the good work Smiley

2 Computing not physically existing as such but made by software to appear to do so: virtual images

This thread was just begging for this. Sorry.

I have also been working on some charting for Primecoin. It's pretty crude so far but a detailed zoomable graph on the difficulty can be found here:

http://192.241.170.170/

The bar at the bottom lets you adjust the data the graph displays, just grab the handles at either end and drag inward. It takes a few seconds to load as it downloads all the diff data up to a few hours ago. I'll fix it so that it only loads enough data for the current zoom and updates the data in real time later.

Let me know what you think.
I'm getting a blank page with an error in Chrome's developer console:
Uncaught Error: NotFoundError: DOM Exception 8 (dygraph-combined.js:2)

Are there any testnet peers online? I can't get any connections at all.  Sad

I used to open and close cd drives and make fake error messages pop up in the library when in high school. While someone was working on a paper I'd pop up a message saying there was a virus that would delete everything if they didn't answer correctly. The question I put in was something like "What is the average rainfall of the Amazon river basin?" and the only answers were Yes, No, and Cancel. By the time they would get a teacher I would close the window. Fun times.
Haha, reminds me of good old Netbus Smiley



And to OP, I think someone is pranking you

Thanks.
You're welcome

Did I miss something or how does this "push" technology differ from Bitcoin's alert system?

I don't think it matters if the coins come back or not. It's bullish in the sense that the SEC saw fit to get involved. If this was a WoW gold ponzi, the chances of that happening are highly unlikely, despite the fact that they are traded for dollars on the secondary market. This will work as an indirect endorsement for bitcoin legitimacy.
My thoughts exactly Smiley
Getting back those coins would be interesting to see... Brainwallets and plausible deniability ftw

Donated some BTC just now, keep up the good work Smiley

BTW, are there any guides how to compile this for Windows (or how to cross-compile with Linux?)
or should Bitcoin-QT building guides apply to this as well?
33  Alternate cryptocurrencies / Altcoin Discussion / Re: Primecoin price -so what's the deal? (and UNOCS invest) on: July 23, 2013, 10:57:30 AM
Primechains are said to be useful for cryptographic applications: http://en.wikipedia.org/wiki/Cunningham_chain
I mainly value Primecoin for the same reason. Its byproduct is more valuable that of Bitcoin (+dozens of altcoins).

By mining Primecoin with my computers I'm contributing to the Primecoin network security AND science Grin

Looking forward to windows binaries. I'll make sure to tip some once they go live Smiley
36  Alternate cryptocurrencies / Altcoin Discussion / Re: WANTED: DEVELOPERS to develop a new coin along similar lines as Primecoin on: July 18, 2013, 02:11:18 PM
How about create a P2P (decentralized) cloud. which can be used to store data or computation.
This cloud can be used to host websites, host personal files, do distributed computation. It has a bitcoin-like block-chain to store the payments/transactions. Something similar to Namecoin but more dedicated.
I think it will be much useful.
There is this neat decentralized data storage software called Bittorrent Sync:

I'm not sure is this related to DigitalOcean's miner rush, but I received this support ticket today:

Greetings,

Preventing abuse is a top priority here at DigitalOcean, and we ask for your help in this ongoing battle. With that in mind, we would like to verify your account details.

Providing your personal information will allow us to better assist you now, and in the future.
Please let us know the following:

a) Your public Twitter handle.
b) Your public Facebook profile.
c) Your personal/business website.
d) Your personal/business blog.

We find that procuring some basic information about our customers to verify accounts is preferable to detailed billing and payment verification, as billing information can be falsified.

Thank you for your time. We look forward to hearing back from you soon.

I didn't mind giving them my personal details. Afterwards I got a nice "Thank you for verifying your account" reply.

I just posted this idea in another thread, but I'm posting it again to reach more XPM miners.

I've started 'banking' single mined blocks in encrypted wallets with each block I find by making a back-up and creating a new wallet each time (where possible).

I figured that if / when someone happens to find a block with an exeptionally long chain, then at least it will be a mined block on a single wallet.

This could give the block a higher value in the future as the coins will also be unspent.

Primecoin is a Scientific Computing Cryptocurrency afterall.
Sounds like a tedious task, if you ask me.
You could just mine into one wallet and dump those private keys into separate wallets later on.
39  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin High Performance on: July 14, 2013, 10:26:38 AM
I'm also running 5 instances of DigitalOcean VPS' (the cheapest ones), they seem to mine with 300-1000pps.

Each or in total?
Each Smiley

Now found 4 blocks in total with all my miners. This is too awesome

Well that's great, and which location?
Current stats:
1st droplet, San Francisco 1 @ ~960pps
2nd droplet, San Francisco 1 @ ~300pps
3rd droplet, New York 1 @ ~350pps
4th droplet, New York 1 @ ~430pps
5th droplet, New York 1 @ ~550pps

There seems to be a lot of variation, give or take a few hundred pps.
