Benchmarking: Virtual curreny mining cudaminer rpcminer on K20

Prerequisites

• Using Centos 6.2 with CUDA 5.0 installed and working
• We needed to install the following

# devel libs needed
 yum install libcurl-devel glibc-devel
 yum install boost-devel boost openssl-devel 

# latest version of cmake 2.8 required
  wget http://dl.atrpms.net/el6-x86_64/atrpms/stable/atrpms-repo-6-6.el6.x86_64.rpm
  rpm -ivh atrpms-repo-6-6.el6.x86_64.rpm 
  yum --enablerepo=atrpms-testing install cmake

Build

  wget https://github.com/Ang3lus/rpcminer-mod/archive/master.zip
  mv master rpcminer.zip 
  unzip rpcminer.zip
  cd rpcminer-mod-master/
  mkdir build
  cd build 
  cmake ../ -DBoost_NO_BOOST_CMAKE=ON
  make
