Non-volatile Storage

January 15, 2016 ~ Adrian Colyer ~ 3 Comments

Non-volatile Storage: Implications of the Datacenter's shifting center - Nanavati et al. 2016 Strictly this is an article, not a paper, but it's a great piece from this month's ACM Queue magazine and very closely related to the discussion on the implications of non-volatile memory that we looked at yesterday. It's also highly quotable! It's ... Continue Reading

Fast In-memory Transaction Processing using RDMA and HTM

October 26, 2015 ~ Adrian Colyer ~ 4 Comments

Fast In-memory Transaction Processing using RDMA and HTM - Wei et al. 2015 This paper tries to answer a natural question: with advanced processor features and fast interconnects, can we build a transaction processing system that is at least one order of magnitude faster than the state-of-the-art systems without using such features? The authors build ... Continue Reading

Cooking the Books: Formalizing the JMM Implementation Recipes

August 6, 2015 ~ Adrian Colyer ~ Leave a comment

Cooking the Books: Formalizing the JMM Implementation Recipes - Petri et al. 2015 A decade ago, the semantics of concurrent Java programs, the Java Memory Model (JMM), was revised and redefined... ... this refinement introduced a formalization called the Data-Race Free (DRF) guarantee. Programs that do not have data races (DRF) in their sequentially consistent ... Continue Reading

Staring into the abyss: An evaluation of concurrency control with one thousand cores

May 1, 2015 ~ Adrian Colyer ~ Leave a comment

Staring into the abyss: An evaluation of concurrency control with one thousand cores - Yu et al. 2014 A look at the 7 major concurrency control algorithms for OLTP DBMSs , and how well they perform when scaled to large numbers (1024) of cores. Each algorithm is optimised for the best in-memory performance possible, but ... Continue Reading

Mojim: A Reliable and Highly-Available Non-Volatile Memory System

April 14, 2015 ~ Adrian Colyer ~ 6 Comments

Mojim: A Reliable and Highly-Available Non-Volatile Memory System - Zhang et al. 2015 This is the second in a series of posts looking at the latest research from the recently held ASPLOS 15 conference. It seems like we've been anticipating NVMM (Non-volatile main memory) for a while now; and there has been plenty of research ... Continue Reading

Specialized Evolution of the General Purpose CPU
