Life Beyond Distributed Transactions - ACM Queue
December 12, 2016 Volume 14, issue 5 PDF Life Beyond Distributed Transactions An apostate's opinion Pat Helland This is an updated and abbreviated version of a paper by the same name first published in CIDR (Conference on Innovative Database Research) 2007. Transactions are amazingly powerful mechanisms, and I've spent the majority of my almost 40-year career working on them. In 1982, I first work
A Conversation with Werner Vogels - ACM Queue
Learning from the Amazon technology platform Many think of Amazon as “that hugely successful online bookstore.” You would expect Amazon CTO Werner Vogels to embrace this distinction, but in fact it causes him some concern. “I think it’s important to realize that first and foremost Amazon is a technology company,” says Vogels. And he’s right. Over the past years, Vogels has helped Amazon grow from
All Your Database Are Belong to Us - ACM Queue
July 23, 2012 Volume 10, issue 7 PDF All Your Database Are Belong to Us In the big open world of the cloud, highly available distributed objects will rule. Erik Meijer, Microsoft In the database world, the raw physical data model is at the center of the universe, and queries freely assume intimate details of the data representation (indexes, statistics, metadata). This closed-world assumption and
The Ideal HPC Programming Language - ACM Queue
AUTHOR FEEDBACK We saw remarkably large reductions in source-code volume. The smallest reduction was in GTC, which already used relatively modern Fortran constructs, had relatively little MPI (Message Passing Interface) parallelism (distributed memory), and had computation and I/O formatting that the human subject was uncomfortable modifying. We saw various indications that the rewritten programs
Software Transactional Memory: Why Is It Only a Research Toy? - ACM Queue
October 24, 2008 Volume 6, issue 5 PDF Software Transactional Memory: Why is it only a Research Toy? The promise of STM may likely be undermined by its overheads and workload applicabilities. Călin Cașcaval, Colin Blundell, Maged Michael, Harold W. Cain, Peng Wu, Stefanie Chiras, and Siddhartha Chatterjee Transactional memory (TM)13 is a concurrency control paradigm that provides atomic and isolat
Coding Guidelines: Finding the Art in the Science - ACM Queue
November 2, 2011 Volume 9, issue 11 PDF Coding Guidelines: Finding the Art in the Science What separates good code from great code? Robert Green and Henry Ledgard, Electrical Engineering and Computer Science, University of Toledo Computer science is both a science and an art. Its scientific aspects range from the theory of computation and algorithmic studies to code design and program architecture
A Generation Lost in the Bazaar - ACM Queue
The Bike Shed August 15, 2012 Volume 10, issue 8 PDF A Generation Lost in the Bazaar Quality happens only when someone is responsible for it. Poul-Henning Kamp Thirteen years ago, Eric Raymond's book The Cathedral and the Bazaar (O'Reilly Media, 2001) redefined our vocabulary and all but promised an end to the waterfall model and big software companies, thanks to the new grass-roots open source so
Triple-Parity RAID and Beyond - ACM Queue
Adam Leventhal, Sun Microsystems As hard-drive capacities continue to outpace their throughput, the time has come for a new level of RAID. How much longer will current RAID techniques persevere? The RAID levels were codified in the late 1980s; double-parity RAID, known as RAID-6, is the current standard for high-availability, space-efficient storage. The incredible growth of hard-drive capacities,
Idempotence Is Not a Medical Condition - ACM Queue
April 14, 2012 Volume 10, issue 4 PDF Idempotence Is Not a Medical Condition An essential property for reliable systems Pat Helland The definition of distributed computing can be confusing. Sometimes, it refers to a tightly coupled cluster of computers working together to look like one larger computer. More often, however, it refers to a bunch of loosely related applications chattering together wi
GFS: Evolution on Fast-forward - ACM Queue
A discussion between Kirk McKusick and Sean Quinlan about the origin and evolution of the Google File System. During the early stages of development at Google, the initial thinking did not include plans for building a new file system. While work was still being done on one of the earliest versions of the company's crawl and indexing system, however, it became quite clear to the core engineers that
A Conversation with Arthur Whitney - ACM Queue
A few well-chosen words about programming languages from a long-time designer When it comes to programming languages, Arthur Whitney is a man of few words. The languages he has designed, such as A, K, and Q, are known for their terse, often cryptic syntax and tendency to use single ASCII characters instead of reserved words. While these languages may mystify those used to wordier languages such as
