Boosting Timestamp-based Transactional Memory by Exploiting Hardware Cycle Counters

2018-05-14

Boosting Timestamp-based Transactional Memory by Exploiting Hardware Cycle Counters Wenjia Ruan, Yujie Liu, and Michael Spear, in ACM Transactions on Architecture and Code Optimization (TACO), Volume 10, Number 4, page 40, 2013, ACM. This paper is interesting in its use of a system level global clock to define a strong ordering of operations across cores.  The […]

The Future of Synchronization on Multicores: The Mulitcore Transformation

2018-04-27

The Future of Synchronization on Multicores: The Multicore Transformation Maurice Herlihy in Ubiquity, September 2014. I’m going to round out the week with a much lighter read.  Despite this, it has some useful observations that underlie some of the other papers that I’ve been discussing. The editor’s introduction to this piece really does a good job […]

Exploiting Hardware Transactional Memory in Main-Memory Databases

2018-04-26

Exploiting Hardware Transactional Memory in Main-Memory Databases Viktor Leis, Alfons Kemper, Thomas Neumann in 2014 IEEE 30th International Conference on Data Engineering, pp 580-591. I have not spent much time discussing transactional memory previously, though I have touched upon it in prior work.  By the time this paper was presented, transactional memory had been fairly well explored […]

Moving to the now

2018-04-15

I’ve been gone for a bit; real life keeping me busy.  Part of that has been exploring the current edge of my technology space.  So I’m going to take a break from the historical paper review (but it will come back) and instead start talking about new storage technologies and the interesting things that we […]

Building the New System

2017-01-05

In my prior life I’d had an opportunity to assemble some awesome tools for my work.  This included both a great desktop (workstation) system as well as a good laptop system as well.   Even at four years old, the desktop system was terrific: dual Xeon processors with 48GB of RAM (24GB each CPU).  Each […]
