Everyone has this huge massively parallelized supercomputer on their desktop in the form of a graphics card GPU.
What is the "hello world" equivalent of the GPU community? What do I do, where do I go, to get started programming the GPU for the major GPU...

I'm not sure of the exact question, but this is what i know .
Hope that helps.
There are tons of calculation using GPU.
Check out CUDA by NVidia, IMO it's the easiest platform to do GPU programming.

I know what a CPU is(I think). It's the thing who's speed is measured in GigaHertz(these days).
However, you hear a lot about a GPU, and letting the GPU take over, not letting the CPU but the GPU do it, GPU-based rendering, etc...
What is this GPU anyway...

What software for GPU benchmarking do you recommend? Also, any suggestions on how to use it?

To others, but it has very beautiful elements in it, and its a joy to watch when you have a new GPU rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool (also called....

In my 2nd system I have a HD6850 cooled by 2x 80MM case fans. What I'd really like to do, would be to set my GPU fans to rev down to 500RPMs when my system is idle based off temps, but have the ability to ramp up to full speed if needed. Does anyone know...

Controlling the 80mm fans directly from the GPU will probably be more hassle than it's worth at, this way here I can control the....
You could monitoring.
Would I link my fan control to my GPU temps? In that situation I don't think you can.

Apparently, in Flash 10, you can use the GPU to calculate shaders, and if the user doesn't have a compatible gpu, it falls back to the cpu. The problem is that the cpu is very slow to calculate the filters, it would be nice to detect if it can't use the...

Use GPU-Z though it will only tell you for what type of DirectX.

I'm curious what "quality" percentages are out there, and any overclocks you can do at what voltages. It would be interesting to see if there is a direct correlation with ASIC quality, voltages, and overclocks. (Predictability how well it can overclock...

I'm interested in implementing an algorithm on the GPU using HLSL, but one of my main concerns is that I would like a variable level of precision. Are there techniques out there to emulate 64bit precision and higher that could be implemented on the GPU...

Answer Snippets (Read the full thread at stackoverflow):
If you need high precision pervasively throughout your algorithm, then the GPU probably isn't.
Decent performance on the GPU, though the code won't necessarily be very pretty or easy to work with.

Is there a standard way of getting the current load on the GPU? I'm looking for something similar to the Task Manager showing CPU%. Utilities such as GPU-Z show this value but I'm not sure how it gets this. I'm specifically interested in AMD graphics ...

For NVidia cards, look at PerfHUD something as simple as a %-use number for the GPU because it isn't that simple.

A good place to start - GPGPU
Also, for the record, I don't think there is such a thing as non-GPU based graphic cards.
Shader languages like Cg for programming general purpose calculations on a GPU.
