ZHT: a zero-hop distributed hashtable

ZHT is a zero-hop distributed hash-table, which has been tuned for the specific requirements of high-end computing (e.g. trustworthy/reliable hardware, fast networks, non-existent "churn", low latencies, and scientific computing data-access patterns). The primary goal of ZHT is excellent availability, fault tolerance, high throughput, and low latencies. we also discuss the use of ZHT as the distributed metadata management in the FusionFS distributed filesystem.
