Very boring rendering
« on: January 01, 2022, 06:58:59 PM »
I am very bored, because it has 28%!
28%? That's not a small amount.
no! 28% in ~ 22.5 hours! :D

I do very little on the computer because I am afraid that the program will crash otherwise. That's why I'm bored!

You re a true hero :worship:  and a very patient one. I can relate to that. Mine is always crashing with incendia, near dead actually. So at the moment I don't even dare to use it :D And Chaotica also takes that long if I want one rendered reasonably good. I don't have the patience anymore or it has to be so amazing, so incredible that I will let me pc suffer for the result ;)

When I win a price  :no: :-*  and got rich I will give you all a super computer  :joy:  but till then.... we just have to suffer like mortals do  :yes: :fp:

The thing is, as the zoom is increased, you will eventually get to that point where the pattern doesn't change insanely. On the contrary, the pattern (around the 'main' morphing) would become less and less interesting. Still, i would like to have a faster machine to try out the limits of Kalles Fraktaler (mandelmachine has a 10^3010 limit).

I think you'll find the other renderers are even slower! But yes, image quality does come first ;)

Still, it's not bad at all with a Radeon 6800xt and 6900xt:

Please note that i render with Mandel Machine (An effective Mandelbrot zoomer)  :yes:

I do long renders in a virtual machine. Every once in a while I make a snapshot of the VM. If the computer has a problem for whatever reason, the render can be resumed from the last snapshot, so not everything is always lost. Another benefit is that you can't easily ruin the render if you don't use the VM for anything else. I always disable mouse integration so even mouse movements don't affect the VM. You lose some performance because of virtualization overhead (about 10% in my measurements) but for really long renders (weeks or longer) it's worth it.

Some information about my VM because it wasn't easy to get it working:

virtualbox 6.0.10 r132072
windows server 2008 in safe mode

The OS is a weird choice. I was trying different versions of windows because I had a problem with very high CPU usage when giving the VM more threads than my CPU has cores. I never figured out why. I stopped trying things when I had something that worked. Maybe a normal windows 7 (which is mostly same OS as windows server 2008) would work as well. I don't know if safe mode was necessary. At least a benefit of safe mode is that there are more features of the OS disabled which makes it faster.

Files can be shared with a shared folder which is possible to set up with the settings of virtualbox. I have a problem where the OS crashes when opening the shared folder in explorer. Therefore I'm using powershell to copy files between the VM and the shared folder with the cp program/command.

So my configuration has some annoying problems and I found workarounds. Maybe the latest version of virtualbox has already fixed all of those problems. I never check that because it takes time and what I have now works.

There's also VMware which costs money. I tried it and it works better than virtualbox but it's limited to 16 threads. VMware may be a good option if your CPU has not many more threads than 16. My CPU has 16 cores, 32 threads, and I give the VM 28 threads so there are 4 left for other programs that I use like web browsers.

I have tried the Virtualbox. I used the GNU/Linux (Debian) operating system to take full advantage of kf. I tried terminal rendering, which also worked. However, when I saved the virtual machine and loaded it again, I got a fatal error. The log text is linked to view. Then I installed debian on my real machine next to windows to try out some programs that serve the same purpose (e.g. "Criu"). I was able to get criu to run, but when I tried to freeze kf, it did not work.
My question is: is there any way on this planet to stop kf, save the progress and run it again another time? The problem is that I like to generate incredibly deep images with kf (much larger than 3e3010, which is the limit of Mandel Machine). This takes time. Only soon i won't be able to run my computer that long (external reasons). That would cause me 'depression'. Tips and possible solutions are extremely welcome!!!

Code: [Select]
Changing the VM state from 'RUNNING' to 'GURU_MEDITATION'
try searching the internet with that log message for solutions, I have no clue myself...

the last time I saw a "GURU_MEDITATION" error was on my Amiga ;)

I have found the solution: Since the computer does not have to be turned off 100% I can use the sleep mode  :o. I just had to disable the startup screen - for whatever reason, after turning the computer back on, kf continues to run as if you had stopped time! fantastic :D
