easy rendering for Rhino in Windows
I have this problem:
I use "flamingo nxt" with "rhinoceros 5.0" on a workstation dual xeon 8 core processor, running "win7 x64".
When processing a flamingo rendering any other program I try to use is greatly slowed. I gave Rhinoceros a limited number of core using windows task manager but does not change anything, even if "the rhino process" uses a very low percentage of cpu all the rest of the software runs go in spurts.
Maybe I just do not know something, anyone has any suggestions?
In my opinion, need a cpu manager inside flamingo and independent of windows 7 in which we can set the processor utilization. In this way we could use flamingo without having to stop all the work with the workstation.
I do not have such slow down. I have a Xeon 6 cores 3,2Ghz , 12Gb Ram with Win-7 . All 12 treads are at 100% CPU when rendering. Depending on what you render, mine eats 4Gb at least, and with a very detailed exterior view (sailboat deck hardware) will eat up to 11Gb. At that point system begins to use the swap file, which might be disastrous in term of over-all performance.
So I'd suggest to watch the available RAM.
Note that Win-7 will show you about 1G Ram "free" out of the max dynamic RAM, but system is already swapping some memory pages to file at that stage.
The best, William
I have 8GB of ram. Actually I happened to check and see 1 GB free, I did not know it was a fake indication, I will try to increase the ram. Many thanks for the tips
I experience some what the same effect, I am running dual quad core processors @ 2.5 Ghz ea. , 14 Gb Ram and dual Quadro FX video cards with Win 7 Ultimate. Flamingo nXt really dominates the system during a rendering, all 4 threads are working it. This box was originally an IBM server I converted to a work station. I can usually work around it and I consider the speed reduction only marginal. I can tell when a render is finished, the cooling fans slow down a lot. So we know what it takes to render - lots and lots of HP (not Hewlett Packard). Hmmm, maybe if I swipe the turbo and inter cooler out of my wife's car.....
On Windows 7 64-bit, Rhino 5 and Flamingo, I was able to set a lower processor affinity and a lower priority to the Rhino.exe process. Flamingo respected this. Are you Rhino 4 or 5?
Flamingo is very efficient with CPU cores. This helps with rendering speeds, but can really run the temperature up in the processors itself. If I am on a box that has trouble keeping the CPU cool, I will drop the power consumption of the CPU. You can do this through Power Options > Advanced settings. I find on my laptop a Maximum Processor State of 99% works well to keep the CPU cool.
I don't think heat is a problem, this box was intended to be a server and has enough fans to be self propelled. Laptops are much more challenged to keep cool, it's a compact environment.
I am using Rhino 4 and just sent a note to sales to do the upgrade to 5. I worked with 5 a bit in Beta mode.
I can do it to Rhino 4 in 64-bit Operating Systems. Are you using intel CPUs.
