Designed and operated a headless Cryptocurrency mining farm setup with CPU-GPU heterogeneous computer workstations utilizing various payment processing techniques and tools. Setup and configured workstations to process and manage over 20 different cryptographic-currencies utilizing the OpenCL and .Net framework. Designed and built custom computer cases and frames required to optimize cooling systems and maximize mechanical clearances. Application knowledge and specialized configuration of software was required for the day to day use and management of payment processing systems. This included the implementation and testing of overclocking and underclocking schemes plus extensive CGMiner configuration and testing in order to maximize share and hash rate submission to mining pools. Maximized system TDP and room temperatures by implementing energy efficient schemes to control power and optimize cooling. Utilized remote administration of systems via Linux and Windows workstations utilizing GPU control parameters laid out for CGWatcher. Successfully processed digital coins from wide variety of SHA-256 and Scrypt based digital cryptographic currencies and then traded or sold them off over secondary markets for a Return On Investment.
