|Passive 2-Phase Immersion Cooling (P2PIC) of Bitcoin Hardware and Implications for other Computing Applications|
|Keywords: Immersion, 2 phase, Bitcoin|
|The hardware used to mine Bitcoin has undergone a dramatic evolution from CPUs and GPUs to FPGAs and finally purpose built ASICs, with each successive generation making the previous obsolete. In this the ASIC era, there has been a divergence in design philosophies. Some favor finer lithography scales and higher power ASICs, some 500-1000W. Others use many, cheaper and lower power ASICS to achieve scale represented at the high end by large industrial and cloud mining operations, some 10s of mega Watts. In this profit-driven market, hardware life cycles are short. Deployment time, capital and operating costs are central to profitability. Traditional air cooled datacenter construction is out of the question as are the fees charged by most hosting services. Surprisingly, P2PIC, usually perceived as an expensive cooling technology, has found a home in this cost sensitive market for a variety of reasons some of which may be quite relevant for more common computing applications. This presentation will describe some recent P2PIC deployments that provide a glimpse of what may be possible if x86 hardware evolves to take advantage of the technology.|
