konchunas/render_hash_2d

Rust implementation of ASIC resistance proof-of-work

renderhash2d

mining hash function when gpu is the only asic

done as part of 6th hackathon http://blockchainua-hackathon.com/

How to launch

Assembled for ubuntu but will also work with any other distribution after npm i and probably even on windows (visual studio needed for compile)

• git clone https://github.com/hu2prod/renderhash2d
• cd renderhash2d
• install nvm
  • curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
  • relogin or source ~/.bash_profile
• install node 11
  • nvm i 11
• install iced-coffee-script globally
  • npm i -g iced-coffee-script
• launch base.coffee
  • ./base.coffee

How to launch gpu code

• ./base.coffee --fn=gpu

How to launch renderhash_2d_hard

• create and fill directory tex_hard with textures from https://rutracker.org/forum/viewtopic.php?t=3597202
  • you must keep only 1001.png - 2820.png if you want recieve same result as me
  • Full torrent recommended
• ./base.coffee --fn=gpu_hard

How to launch renderhash_2d_hard_unpack

unpack is only optimized version when you don't need decode png to texture atlas

• Make sure that you have enough free space, because unpacked images are 1.5 times larger than original one's
• mkdir tex_hard_unpack
• ./tex_hard_unpack.coffee
• wait
• ./base.coffee --fn=gpu_hard_unpack

How to launch renderhash_2d_hard_plus or renderhash_2d_hard_plus_unpack

• ./base.coffee --plus --fn=gpu_hard
• ./base.coffee --plus --fn=gpu_hard_unpack

Throubleshooting

gpu code doesn't work

e.g.

Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
Segmentation fault

• make sure that at least any other open source gpu miner works. (Claymore is not open source)
• probably binaries are bad for your system. Make npm i to make sure that binaries using exactly your env
• clinfo should list your openCL compatible GPU
• write me (fb virdvird), I'll try to investigate. (еще не зажрался)
