RezSort: Sorting 1TB using Energy-efficient NVMe SSDs

This paper summarizes the configuration, benchmark steps, and results of a system that was built to improve upon the 1TB JouleSort benchmark [8] (Daytona Category). We use a desktop machine equipped with energyefficient SSDs and show that we can improve upon the current 2013 [4] and 2019 [6] JouleSort world records by 17% and 15%, respectively. Our desktop machine is a modified Asus ROG Strix G15CK build [2]— equipped with Intel Core i7-10700 CPU running @ 2.9 GHz, and paired with 16 GB DDR4 DRAM. We use 2× 1TB SK hynix Gold P31 NVMe SSDs and a 2TB Samsung 980 Pro NVMe SSD. Using this hardware, we are able to perform a 1TB sort (with 10 records) in an average time of 1379 seconds running at 100.4 W—requiring a total of 138,416 joules.
