Co-Processors, GPGPU, and Heterogeneous Computing

June 26, 2017 By Stephen 2 Comments

I’ve been thinking a lot lately about microprocessors, from the many-core CPUs that AMD and Intel introduced recently to the massively scalable GPGPU processing that’s taking machine learning by storm. After years of consolidation on commodity x86 CPUs, it seems that the computing paradigm is turning again to specialized offload processors. This trend towards heterogeneous computing will change the face of hardware, from mobile devices to the datacenter.

Datacenter History: Through the Ages in Lego

October 22, 2013 By Stephen 9 Comments

Readers of my blog know that I love computer history. Therefore, I decided to focus my entry in Juniper Networks’ “Build the Best (Lego) Data Center” contest on the history of computing. Specifically, I would re-create key historic machines to contrast them with a modern view.

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

The 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

We Live in the Future: Robotic Cat Litter Boxes!

May 8, 2010

This post is a bit of a break from my usual gadget-fest, but the object in question isn’t that far off: It requires electricity, costs more than average humans can justify, and simplifies a task we’ve all been doing fine up until now. That’s right: An overly-expensive electric cat litter box. Predictably, I love it.

What’s the Deal with Containers?

October 21, 2016

Lately, it seems like everyone just can’t stop talking about containers. But I’m sensing a distinct lack of real understanding of the technology from many people, not to mention lots of confusion about what containers really mean for today’s datacenter folks. So I set about learning more and figuring out for myself what the deal is with containers. Here’s where I’m at.

What’s the Difference Between a Jailbroken and an Unlocked Phone?

May 5, 2012

If you’ve traveled much, you’ve probably run across â€œunlockedâ€ mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about â€œjailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.

Thinking About Storage In a New Way, From Cloud to Flash, with Dropbox and Fusion-io

July 23, 2013

I’ve been a storage revolutionary for quite a while, looking for new ways of data storage rather than technologies that perpetuate the same old approaches. That’s why I’m excited about the implications of two very different API access methods announced by Dropbox at DBX and by Fusion-io today at OSCON.

The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

The Rack Endgame: Open Compute Project

September 17, 2014

On reading my thoughts about the evolution of enterprise storage, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new architecture, and perhaps not the best one for the enterprise.

Sony NEX-5 Camera Review

September 15, 2010

The world of photography is like so many others: A vast gulf separates the amateurs and enthusiasts, from equipment to nomenclature to skills. I am decidedly in the amateur camp when it comes to photography, but I recently upgraded to a new compact interchangeable-lense camera, the Sony alpha NEX-5. It is an excellent match for my needs, allowing me to expand my skills and explore more advanced photographic techniques without sacrificing portability and ease of use.

Scaling Storage Is Hard To Do

June 4, 2013

Data storage isn’t as easy as it sounds, especially at enterprise or cloud scale. It’s simple enough to read and write a bit of data, but much harder to build a system that scales to store petabytes. That’s why I’m keenly focused on a new wave of storage systems built from the ground up for scaling!
