New major optimization that reduces number of multiplications during point addition from 3 to 2. This gives a boost of up to 14% on my nVidia GTX 1070. Progress counter for initialization has also been added. Profanity is a high performance (probably the fastest!) vanity address generator for Ethereum. Create cool customized addresses that you never realized you needed! Recieve Ether in style! Wow!

Usage usage: ./profanity [OPTIONS]
Basic modes: --benchmark Run without any scoring, a benchmark. --zeros Score on zeros anywhere in hash. --letters Score on letters anywhere in hash. --numbers Score on numbers anywhere in hash. --mirror Score on mirroring from center. --leading-doubles Score on hashes leading with hexadecimal pairs
Modes with arguments: --leading Score on hashes leading with given hex character. --matching Score on hashes matching given hex string.
Advanced modes: --contract Instead of account address, score the contract address created by the account's zeroth transaction. --leading-range Scores on hashes leading with characters within given range. --range Scores on hashes having characters within given range anywhere.
Range: -m, --min <0-15> Set range minimum (inclusive), 0 is '0' 15 is 'f'. -M, --max <0-15> Set range maximum (inclusive), 0 is '0' 15 is 'f'.
Device control: -s, --skip Skip device given by index. -n, --no-cache Don't load cached pre-compiled version of kernel.
Tweaking: -w, --work Set OpenCL local work size. [default = 64] -W, --work-max Set OpenCL maximum work size. [default = -i * -I] -i, --inverse-size Set size of modular inverses to calculate in one work item. [default = 255] -I, --inverse-multiple Set how many above work items will run in parallell. [default = 16384]
Examples: ./profanity --leading f ./profanity --matching dead ./profanity --matching badXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXbad ./profanity --leading-range -m 0 -M 1 ./profanity --leading-range -m 10 -M 12 ./profanity --range -m 0 -M 1 ./profanity --contract --leading 0
