Publication at 2018 HEART Conference: Accelerating Memcached on AWS Cloud FPGAs

We were invited to publish our AWS F1 Memcached acceleration work at the 2018 International Symposium on Highly-Efficient Accelerators and Reconfigurable Technologies (HEART). Our paper describes in detail the Memcached accelerator on AWS F1 as well as many of the interesting things (good and bad) that we learned about the F1 infrastructure along the way. J. Choi, R. Lian, […]

Deep Dive into the World’s Fastest Cloud-Hosted Memcached

We attended RedisConf last week to learn more about Redis and meet users who are using Redis/Memcached. Many people were interested in our 11M+ Memcached ops/sec result achieved with a single AWS EC2 F1 instance, but the 1-page summary document was not comprehensive enough to answer all the questions. Here we explain in more detail about the hardware […]

World’s Fastest Cloud-Hosted Memcached: 11M+ Ops/sec at 0.3 msec Latency with a Single AWS F1

We are pleased to present the world’s fastest cloud-hosted Memcached on AWS using EC2 F1 (FPGA) instances. With a single F1 instance, LegUp’s Memcached server prototype achieves over 11M ops/sec, a 9X improvement over ElastiCache, at <300 μs latency. It offers 10X better throughput/$ and up to 9X lower latency compared to ElastiCache. Please refer to […]

Accelerated Memcached on AWS Cloud FPGA (F1)

On our last blog post, we wrote about using LegUp to perform networking processing on AWS cloud FPGAs (F1). In this post, we describe accelerating Memcached on AWS F1. Memcached is a high-performance distributed in-memory key-value store, widely deployed by companies such as Flickr, Wikipedia and WordPress. Memcached is typically used to speed up dynamic web applications […]
