Primecoin High Performance Version 13 ===================================== This is the high performance version of Sunny King's Primecoin tree. Features: * Extended sieve algorithm * Cache-friendly segmented sieve * Adjustable sieve parameters * Mining threads use GMP for faster bignum arithmetic Donations are welcome if you want to support my work. BTC: 1EaHwHBWeoJtSM2jEdx9Su1NcKvdXbsqxX LTC: LPD1zDChmqcqKGHFHuLX2JWMMEC5jD5J4j XPM: AJHjbkVzHhHugd5bpKDtddVDfhtEB8jQZ4 Sieve parameters ---------------- * -sievesize determines how many numbers go through the sieve in one go. The default value is 917504 (default value of -l1cachesize times 32). This value has very little impact on performance. * -sievefilterprimes determines how many primes factors will be filtered out by the sieve. The default value is 7849. This value has a minor impact on performance. * -sieveextensions determines the number of sieve "extensions". Each extension will effectively process an additional set of numbers through the sieve relatively cheaply. The default value is 9. This value has a minor impact on performance. * -l1cachesize determines the sieve segment size (in bytes). This should be the size of the L1 or L2 cache (or some other number close to them). The default value is 28672. This value has a minor impact on mining performance. * -primorial determines the primorial that is used as a multiplier in all candidate numbers. This should a small prime number such as 47 or 53. Use the parameters -debug -printprimorial to see which primorials are used by default. This value has a minor impact on mining performance. Some parameters can be changed on the fly using the following RPC commands: * setsievefilterprimes * setsievesize * setsieveextensions Old and removed parameters: * -sieveroundpercentage * -sievepercentage Primecoin 0.1.2 BETA ==================== Copyright (c) 2013 Primecoin Developers Distributed under conditional MIT/X11 software license, see the accompanying file COPYING.

Intro --------------------- Primecoin is a free open source cryptocurrency that implements the first scientific computing proof-of-work for cryptocurrencies. The unique proof-of-work design searches for rare prime formations, providing experimental value for mathematicians to further understand the nature and distribution related to prime number, a simple yet mysterious construct of arithmetic that continues to baffle the top minds of mankind. Upgrade -------------------- First backup wallet. Then follow setup instructions. Double check balance after completing setup and starting up client. Setup -------------------- You need the Qt4 run-time libraries to run Primecoin-Qt. On Debian or Ubuntu: `sudo apt-get install libqtgui4` Unpack the files into a directory and run: - bin/32/primecoin-qt (GUI, 32-bit) - bin/32/primecoind (headless, 32-bit) - bin/64/primecoin-qt (GUI, 64-bit) - bin/64/primecoind (headless, 64-bit) Website: http://primecoin.org Forum: http://ppcointalk.org Github (source code + sig + wiki): https://github.com/primecoin/primecoin Sourceforge (release builds): https://sourceforge.net/projects/primecoin Bitcoin 0.8.6 BETA ==================== Copyright (c) 2009-2013 Bitcoin Developers Distributed under the MIT/X11 software license, see the accompanying file COPYING or http://www.opensource.org/licenses/mit-license.php.

Intro --------------------- Bitcoin is a free open source peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending. Setup --------------------- You need the Qt4 run-time libraries to run Bitcoin-Qt. On Debian or Ubuntu: `sudo apt-get install libqtgui4` Unpack the files into a directory and run: - bin/32/bitcoin-qt (GUI, 32-bit) - bin/32/bitcoind (headless, 32-bit) - bin/64/bitcoin-qt (GUI, 64-bit) - bin/64/bitcoind (headless, 64-bit) See the documentation at the [Bitcoin Wiki](https://en.bitcoin.it/wiki/Main_Page) for help and more information.
