Ouais, ben salut quoi

With cuda, you can write to arbitrary memory locations. With a shader, you're limited to writing to the pixel you're processing. That right there is probably the single biggest advantage of cuda. Yes, there are work-arounds with vertex/geometry shaders, but even in the best case, these will implicitly flush the instruction buffer, texture caches, require communication with the CPU, take a detour through triangle setup, ect. Can we say context switches? Thus, for scatter, it's clear that cuda is vastly more efficient.

Basically, the trade off is simple:
Cuda can do anything a shader can, and some things a shader can't, and almost always as fast or even a bit faster.
But cuda only works on Nvidia GPUs.

I would add that shared memory is the other big advantage of CUDA/OpenCL over pixel shaders. This can provide big performance improvements in bandwidth-limited image processing algorithms.

---

- Can set number of threads
- Can set number of blocks
- Can optimize using different memory spaces available
- Can customize thread load balancing to one's choosing

These are perhaps the most important points. There is a lot more transparency with CUDA. You know what magic numbers affect performance and you can tune your code appropriately to make sure you get the most out of the video card.

Over at GDC Nvidia today announced the Testla Volta V100 processor, this is a Volta based GPU based on Tensor architecture. Tesla Volta V100 will be fabricated on TSMC’s 12nm finfet process, pushing the limits of photo lithography as this GPU is huge.

The Tesla Volta V100 graphics processor has 5,120 CUDA / Shader cores and is based upon an incredible 21 Billion transistors. It offers what Nvidia calls 120 Tensor TeraFLOPS of performance. Gaming wise it would perform in the 15 TFLOP (fp32) region, delivered by a new type of architecture called Tensor cores. The R&D behind this did cost Nvidia many years and about $3 billion worth in investments, CEO JHH stated in his keynote. The first server and deep learning segmented products based on Tesla Volta V100 will become available in Q3 2017. The new Tensor Core is based on a 4×4 matrix array and fully optimized for deep learning. Nvidia stated, they felt Pascal is fast, but isn't fast enough. I already stated that the GPU is huge, it's 815mm2 huge and would fit roughly the palm of your hand.

   Massive 815mm2 die size
   12nm FinFet (TSMC)
   21B Transistors
   15 FP32 TFLOPS / 7.5 FP64 TFLOPS
   120 Tensor TFLOPS
   16GB HBM2 which manages @ 900 GB/s
   5120 Shader processor cores

Omg your rooms are beautiful. Mine are functional... at best.
Ahem. In any case, I do use personal rooms as opposed to a barracks for the reasons you outlined. I have small mediocre statues in some rooms, and my colonists are about as happy as they can be for working in a sweatshop.

What do you mean by functional rooms? Aren't those sleeping bags good enough?

You use bags?
I just carve a square on the floor.....

You carve a square on the floor? I just say go lie down in that corner......

---

You lie down in a corner? My whole family lived in a shoe in the middle of the road. **

Luxury! My family lived under the road, and we had to share our hole in the ground with a family of carnivorous rats!

---

You ingrate! I lived in a 7 square-foot subterranean cave with a bunch of rapey, cannibalistic reavers constantly biting me for twelve years before I could earn enough to move to the cave with the rats!

---

BAH! Paradise! Me and my family lived, with 100-ish other families in a very hot cauldron in 1st circle of Hell. I had to wake up at 3 am every morning, half an hour BEFORE I go to sleep, travel all the way to 9th circle to poke some traitor in the eye. Every day! No weekends! And I got payed in 100 whips with horse dick across my face per day.

The OpenCL 2.0 specification is going on four years old and it appears NVIDIA's proprietary drivers are finally getting ready to support this newer GPGPU computing specification.

Embarrassingly, NVIDIA hasn't supported OpenCL 2.0 by their drivers as they have been more focused on their own GPU computing standard, CUDA. Their drivers have been limited to OpenCL 1.2 even while the OpenCL 2.0 specification is over three years old and a NVIDIA employee is who leads The Khronos Group. Fortunately, in 2017, it's looking like things are changing.

vulkan vulgarisation (english):

If you're really new to 3D graphics, OpenGL, or one of the traditional APIs, is the best place to start learning and not get totally swamped by all the details that you need to drive Vulkan. The interesting thing is over time, the middleware layer could evolve to potentially provide some interesting learning platforms over time. Right now, if you are starting from scratch, start with OpenGL.

In OpenGL, the only choice for writing shaders is to use GLSL, and pass the GLSL into the driver at runtime. In Vulkan, you can also write in GLSL, and use an offline tool chain to translate that to SPIR-V. (Standard Vulkan only accepts SPIR-V). There are plenty of other choices, and there will likely be lots of people experimenting with different languages and different kinds of tool chains, middleware, and game engines as a variety of ways of generating the SPIR-V that goes into the driver. So you can do it the way it works for OpenGL, or you can experiment with the new and different ways. Some of those can be linked directly into an application, so you don't have to rely solely on offline support. We usually call it off-driver support, but you could do it online by using a side tool real-time. It just isn't part of the core Vulkan drivers stack.

If you have been following the Indie game market on steam (or gog), you will notice that many of the most successful indie games are 2D games, where as very few (recent) 2D AAA games have garnered the same success. And vise versa for 3D games. I think much of this boils down to the above perceptions… 2D is for indies, and 3D is for AAA. If you are and indie making a AAA game you have to either A) battle that perception and inform the community of who you are repeatedly, or B) somehow make a AAA quality game with 1/50th the team size, and 1/1000th the team budget. Ofen this will lead to a good game getting crushed by unreasonable expectations of the 3D perception… Likewise if you are a AAA team making a 2D game, then you run the risk of the community simply expecting more from you, and no matter what you make they may/will respond with “But its not 3D” and down vote you. This can again lead to a good game getting crushed under the weight of expectations that are unreasonable.

I would say for an indie studio it is a win for 2D, while for a AAA studio it is a win for 3D.

if by any chance your 3D rendering happens to fail on 1%3 of devices (which is really difficult to avoid in real world) – your support will be able to say “hey, try unchecking this checkbox”, solving the problem and saving you from quite a lot of disgruntled customers (at least until you figure out the problem, which may take a while); this tends to relieve the pressure on both support and development A LOT.

And last but not least, an ability to switch off that nice-looking but battery-expensive shaders when I am away from my wall socket, brings you as a developer additional brownie points from me as a player :-).

as a rule of thumb, physics is done by CPUs, and visuals are done by GPUs.

In fact, as the police run out of things to do, they are becoming more inventive about what constitutes a crime, says Kanako Takayama of Kyoto University. In one recent case, she says, they arrested a group of people who had shared the cost of renting a car, deeming the arrangement an illegal taxi. Some prefectures have begun prosecuting people who ride their bicycles through red lights

Fifteen years ago police in Hokkaido, in Japan’s sparsely populated north, conspired with yakuza gangsters to smuggle guns into the country so they could meet quotas for finding them.

The courts dismissed the case of the beer thief in Kagoshima, despite all the work that went into it.

Japan is almost crime-free not thanks to the police, says Yoshihiro Yasuda, a campaigning lawyer, but because people police themselves.

This tutorial will teach you the basics of using the Vulkan graphics and compute API. Vulkan is a new API by the Khronos group (known for OpenGL) that provides a much better abstraction of modern graphics cards. This new interface allows you to better describe what your application intends to do, which can lead to better performance and less surprising driver behavior compared to existing APIs like OpenGL and Direct3D. The ideas behind Vulkan are similar to those of Direct3D 12 and Metal, but Vulkan has the advantage of being fully cross-platform and allows you to develop for Windows, Linux and Android at the same time.

The problem with most of these APIs is that the era in which they were designed featured graphics hardware that was mostly limited to configurable fixed functionality. Programmers had to provide the vertex data in a standard format and were at the mercy of the GPU manufacturers with regards to lighting and shading options.

As graphics card architectures matured, they started offering more and more programmable functionality. All this new functionality had to be integrated with the existing APIs somehow. This resulted in less than ideal abstractions and a lot of guesswork

Synaptics was founded in 1986 by scientists and engineers Federico Faggin and Carver Mead, inspired by their interest in neural networks and their applications in technologies. Faggin and Mead applied their research and discoveries on neural networks and transistors on chips to build touch sensing solutions. The name of the company was derived from this combination, blending synapse and electronics.
