Primate Labs | http://www.primatelabs.com/ | Toronto, Ontario, Canada

Primate Labs is looking for software developers to work on Geekbench, our popular cross-platform processor benchmark. You will help develop and analyze benchmark tests for future versions of Geekbench in addition to working on the application itself.

We're looking for someone with a solid C++ background. It would be nice if you had experience with any of the following technologies (but by all means these are not mandatory): C++11, GPGPU APIs (e.g., OpenCL or CUDA), and code optimization and profiling tools.

Benefits include competitive salary and vacation time, medical and dental benefits, and flexible work hours.

This is a full-time position in our Toronto, Ontario office. Please email [email protected] to apply.

Unfortunately the Samsung Chromebox Series 3 uses an Intel processor, not an ARM processor.

A slightly less "friendly" alternative to an ARM-based Chromebox would be the NVIDIA Jetson TK1. It's a developer board with an actively-cooled Tegra K1 SoC. We've been experimenting with these boards over the last two weeks and haven't encountered any stability problems. We're not pushing them as hard as Linaro does but we're certainly putting them through their paces.

Not all handsets are included in the chart. The Geekbench Browser has a list of handsets which it uses to build the benchmark chart. This list contains model and processor information and is manually maintained; if a handset isn't in the list, it's not included in the chart. I thought all of the S3 models were included in this list, but apparently I'm wrong. I'll make sure this list is up to date.

Geekbench is built with the NDK (since all of the benchmarks are written in C or C++). There was a bug in Android 4.0.3 and earlier that caused Android to select the ARMv5 libraries instead of the ARMv7 libraries (which caused a massive drop in performance). This was fixed in 4.0.4 which is why there's a huge jump in performance between the two versions on the One X.

Geekbench developer here.

Out of curiosity I built Geekbench with Xcode 4.5 (it's not available on the App Store yet) and took a look at the code generated for the armv7 and the armv7s architectures. Surprisingly there weren't a lot of differences between the two. The biggest difference I saw was that Xcode uses conditional VFP instructions (e.g., vaddeq.f64) for the armv7s but doesn't use them for the armv7 despite the fact that these instructions are supported by the armv7. My guess is that the A6 implementation of these instructions is much faster, but I won't know for sure until I can run benchmarks on the iPhone 5 myself.

Also, I could only find two instructions (sdiv and udiv) that Xcode generates for the armv7s architecture that aren't supported by the armv7 architecture.

The results on the chart aren't averaged by name; they're averaged by name, by processor, and by processor frequency. We're aware that many Android devices with the same name use different processors, and of the fact that many Android devices are both over- and under-clocked by enthusiasts.

Sorry if this wasn't clear from the preamble on the chart; I'll have to update it.

jfpoole | 14 years ago | on: X86's Days as a Consumer Microarchitecture are Numbered

I'm excited about ARM processors for low-power applications but I can't see ARM replacing x86 processors (even in the consumer space) until ARM performance is comparable to x86 performance. Right now the slowest MacBook Air is 6x faster than the iPad 2; until the difference is 2x or less I just can't see companies or consumers switching to ARM.

jfpoole | 14 years ago | on: Joel Spolsky On Tech Hiring: Beware the Exploding Offer

Sometimes the insecurity is justified. I've seen former managers extend offers only to retract them two days later when the staff requisition was retracted by upper management. If you're on a project and you need people this encourages you to hire as quickly as possible.
