If that's the real reason Apple won't expose OpenCL and why Google has been aimlessly puttering with reinventing Ian Buck's Ph.D. thesis for the past 4 years, I just died a little inside. That said, IOS 8 exposes WebGL, no?

Say what? You can get insane single-precision efficiency out of GTX 980. Double-precision OTOH is a disaster (1/150 yes 1/150 as opposed to GK104's 1/30 or so). But for most machine learning, double-precision is ove

You can probably figure out why 3x3 or smaller convolutions would be faster without much thought: hint FP performance is improving much faster than either internal bandwidth or CUDA kernel launch latency. And IMO this opens up the window fo

Your point? IMO it's an intriguing but completely unproven technology. In contrast, GPUs (a newer technology than quantum computers) waltzed out of the gate with 100x to 1,000x speedups over Pentium IV CPUs barely a decade into their

No I'm suggesting that the body is a complex system and if you solve one component of the problem, another component ultimately fails until you run out of components (hint, just like software) Every time a cell divides, it has a chance

Hey Michael, I loved your book on Quantum Computing, but don't get me started on D-Wave or as I see it: $15M for a huge magic box that might be faster than a $15,000 GPU cluster for some problems. But seriously, the book rocked, an
