Indigo Renderer GPU acceleration
Re: Indigo Renderer GPU acceleration
Quadros should be fully compatible, though it hasn't been tested.
BTW, I'm solving a final issue with the GUI now, unrelated to GPU stuff, after which I'll write up the changelog and do the release.

Cluster with a few i7 and high end quadros... Gaaah

Re: Indigo Renderer GPU acceleration
That's some very impressive firepower Make sure it's just one Quadro per box for now though, we're usually CPU limited.
Re: Indigo Renderer GPU acceleration
Yes, it will be a couple of boxes with 1 GPU per machine.
With a powerful GPU such as a high end quadro, is it worth to have a dual CPU machine (such as a bi xeon), or is an i7 enough? I suppose you cannot answer right now. The best is maybe to buy one of each and decide what to add next.

Re: Indigo Renderer GPU acceleration
Yes, that is probably the best way to play it.
Soon after the release of the first beta I want to add some diagnostic info showing the CPU/GPU load.

Re: Indigo Renderer GPU acceleration
What about the Tesla C1060?

Re: Indigo Renderer GPU acceleration
That's even better, because it shouldn't lag your computer at all. When using the same device to compute and display, there will be some lag in the displaying; in future releases we'll be able to tune the latency vs throughput tradeoff.
I assume you'll be using Linux for these? We don't yet have CUDA running on non-Windows platforms, but it should hopefully be reasonably straightforward.

Re: Indigo Renderer GPU acceleration
The OS can be linux. The machine is not purchased yet so we have choice...
So you confirm the tesla will be supported?

Re: Indigo Renderer GPU acceleration
I haven't tested it, we don't have access to such hardware at the moment. However, we go through a standard CUDA interface, which one can expect to dutifully report and use this first-class CUDA device.
Re: Indigo Renderer GPU acceleration
What about PCs with multiple GPUs ? I know Indigo will use only one for now, but can we chose it?
For instance, on a PC with a geforce and a Tesla, can we choose to use the Tesla?

Yes, you can select the GPU that is to be used by Indigo.galinette wrote:What about PCs with multiple GPUs ? I know Indigo will use only one for now, but can we chose it?

Re: Indigo Renderer GPU acceleration
IS GPU Indigo going to allow some form of "real time" control like that SmallLuxGPU. It uses a CPU and GPU combo as well.

Even when using my CPU only with it, it's pretty nice :)
Being able to interact with your scene with immediate feedback is a whole new level.

Re: Indigo Renderer GPU acceleration
Any idea about balance of CPU GPU?
I've a lowly Intel 2ghz dual core on my main machine. I'm slowly upgrading. Its now maxed out at 8GB of ram. My next upgrade will be either a CPU or GPU (not both at the moment)
£160 on a Quad core upgrade or £160 on a new Graphics card? What would be best for the new Indigo GPU renderer?
Or maybe divide that budget and drop in a faster dual core and a new but less spec'd out graphics card? Any clues from the figures so far?

CoolColJ: We'll of course try to put as much flexibility in the rendering engine as possible, though it's a little too early to say exactly what - we'll see once the beta is out!
Russidgo: Since we use a hybrid approach the CPU will still be important, and I would suggest springing for a quadcore since that will also benefit bi-directional, which is still a very tough algorithm to beat, even with GPU bruteforce path tracing. So it's both necessary for fast GPU rendering, and sufficient for fast CPU tracing!
I'm busy resolving the last of the build issues now (the 32bit build doesn't run without CUDA installed) and putting together some new testscenes; when that's done it's finally time to release the first beta.

Re: Indigo Renderer GPU acceleration
I agree with CoolCoJ, the ability to move the lights & camera around inside indigo would be fantastic!lycium wrote:CoolColJ: We'll of course try to put as much flexibility in the rendering engine as possible, though it's a little too early to say exactly what - we'll see once the beta is out!
But thats further down the line, one (awesome) step at a time. :)
