Scalable Knowledge-Graph Analytics at 136 Petaflops/s – Data Readme


This dataset contains data that was presented and analyzed in our paper "Scalable Knowledge-Graph Analytics at 136 Petaflop/s" [1]. The dataset is based on the COVID-19 Open Research Dataset (CORD-19) [2]. The CORD-19 dataset is a collection of scientific publications on SARS-COV-2, COVID-19, and other coronaviruses. This readme describes how we used the CORD-19 data to create a knowledge graph that was the input into our Distributed Semiring All-Pairs Shortest Path (DSNAPSHOT) algorithm [1]. The readme also describes the output of the algorithm. Both the input graph and the output all-pairs shortest paths information are shared in our dataset ( The download size of the dataset is 155 GB. The unpacked dataset is 518 GB in size.
