memcached-sgx's Introduction

Zero-config (ZC) switchless

This is a research project aimed to remove the need for configuring Intel SGX switchless calls at build time.
Doing this obviates the performance degradation due to bad configurations.
This repo follows our publication at the IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2023

System architecture

The in-application scheduler periodically obtains application metrics such as number of fallback calls to determine the most appropriate number of worker threads to use for switchless calls.
The number of worker threads is chosen in such a way as to minimize waste of CPU resources while providing good performance relative to a non-switchless system.
