cs214-semisort's Introduction

CS214 Project 2

Parallel Semisort

Results

This was run on a 48-core (Intel(R) Xeon(R) Silver 4214R CPU @ 2.40GHz) server with 755GB RAM. A test is run 4 times and the performance is the average of the last 3 runs (first run is a warm-up round). There are 1e9 elements in every test.
