In my experience, Jensen Huang's keynotes are unprofessional in the best possible way. I remember thinking during an entire GTC presentation "Wait, this guy is the CEO?" He seemed like an excited engineer who happened to stumble onto stage.

He is an Amazing salesman though

Tesla is famous in the US for inventing polyphase AC and induction motors, but this is really one of these stories were a bunch of people invented the same thing very closely to each other due to a precipitating reaching of understanding. Note that Tesla's designs were IIRC two-phase which is largely inferior to three-phase. The push for three-phase and associated designs and inventions (three phase transformers on a…

> but this is really one of these stories were a bunch of people invented the same thing very closely to each other due to a precipitating reaching of understanding. This is by far the dominant case of invention. Truly independent work is incredibly rare.

And yet we grant patents so liberally, giving a windfall to the first person who files.

> Do you work for AMD I do not. And I use NVidia hardware regularly for GPGPU. But I hate fanboyism. > NVIDA open-source their CUDA implementation to the LLVM project 5 years ago Correction: Google developped an internal CUDA implementation for their own need based on LLVM that Nvidia barely supported it for their own need afterwards. Nothing is "stable" nor "branded" in this work.... Consequently, 99% of public Open…

> That you can't compile CUDA to AMD GPUs isn't NVIDIA's fault, it's AMD, for deciding to pursue OpenCL first, then HSA, and now HIP. Using a branded & under patent concurrent proprietary technology and copying its API for your own implementation is Maddness that will lead you for sure in front of a court. It seems that even Google understood that the hard way ( https://en.wikipedia.org/wiki/Google_v._Oracle_America…

How come? There is a CUDA C++ and CUDA C toolchains available under a MIT license, large part s of which are contributed by NVIDIA.

How can they sue you for using something that they give you with a license that says "we allow you to do whatever you want with it" ?

I don't like that people downvoted you for asking a question. If someone thinks the question is stupid or not doesn't mean that a downvote is warranted. (nor an upvote, answer the question and move on.) To answer though; it's just a coincidence, as you might already know Nvidia uses famous scientists (especially in the field of electricity) as the names of their microarchitectures. * Volta (Alessandro Volta, inventor…

Ironically, that's what they put on the PCB. Those yellow things on both side of the chip package are actual micro transformers made of some material with very tricky magnetic properties.

I wonder, was the name Ampere a reference to its titanic current consumption?

Those only reason to put those on the PCB would be to provide current above 1kA

Saw him recently for the first time and really enjoyed his enthusiasm and "real-ness". At one point during the (long) talk, he opined that he really wished he hadn't drank so much right beforehand (i.e., full bladder). Ha.

Google v Oracle is still unsettled. Most other legal precedent was that it was fine to clone an API.

> Most other legal precedent was that it was fine to clone an API. CUDA is more than an API. It is a technology under copyright and very likely patented too. Even the API itself contains multiple reference to "CUDA" in function calls and variable name.

None of that protects it from being cloned under previous 9th circuit precedent except maybe patents, but I'm not aware of any patents that'd protect another against CUDA implementation.

I thought he was nerdy business man trying to be cool and it was / is cringy, but years ago I saw him talking with TSMC founder on computer history museum and since I think highly of the guy and really appreciate him. There's a dose of genuineness behind him and you can tell.

And even before that there was: * GeForce (for Andrea Geforce, the first to use the color electric green) * Riva (for Jose Riva, the discoverer that you can use TNT to generate electricity.)

well done

I thought for this the standard practice is fixed-point. Requires more planning and mental gymnastics but usually much faster and gives you full control of the precision. Maybe this has changed from my DSP days.

I am confused. If you used to work in DSP then you know the standard practice involves MATLAB, where the default is double precision. This is also the default datatype in NumPy. Most engineers don't like working in fixed-point unless they have to for other reasons, like moving it onto an FPGA or something.

Why not? Because of interop with other libs/tools? It's not _that_ hard, but I can see the problem if whole workflow isn't like that.
