Freeing up system memory?

jeffreymorris1 · ‎04-30-2012

My computer has 12GB of system memory and City Engine keeps on asking me to purge system memory when working with huge files. How do I free up system memory before running City Engine?

Hi !

Try creating a new scene which has no projection set yet.

It may be that the projection note down there messes up the layout and pushes the mem indicators out of the way.

Also, you can resize the whole CE window to show it bigger than 1 screen. I usually work on 3 screens here .. 😉

Lemme know ..

With a projected scene, I can never see both the memory indicators no matter where I put all the windows. Will this be fixed in a service pack do you think?

Hi Jennifer..

Can you post a screenshot with your full screen ?

Please also let me know what resolution your monitor is working on ..

Kind greetings and thanks.

[ Sorry for the inconvenience with the GUI.. ]

I am running a 64-bit operating system.

I forgot to tell you that both screens are at a resolution of 1280 x 1024.

Hi ..

Did you get my PM ?

I guess it'd be best we can so a screensharing session to track this down.

E.g. via Skype or so. Please PM me, we can then figure out the details.

Hello,

I`m having the same problem with CE, also movement in the scene is with lag. A few times I was getting a fatal error and the application just ended( I think it saved a txt file on my desktop with specification of the error).

JRE is 64 bit and CE also on 64 bit. I have 8 GB of RAM and a 2GB GPU

In my .ini file xmx is 4096 and I`m not sure what value to set ( 8192 maybe? ).

Can you give me any suggestions?

Thanks !

Hi,

Do NOT assign more than half of your system memory to Java. This memory is reserved by CityEngine and no other application can access it.

If you still get 'out of memory / purge' messages, you'll need to get more RAM. I'd recommend 16 GB.

Ok ?

Hi Matt,

Does CityEngine benefits from using 2 GPU NVIDIA GeForce GTX 970 in SLI ?

Thanks !

Hi,

I'm not perfectly sure if it will run technically - I assume it will be no problem and is supported.

But I doubt there's any advantage using SLI for any work in CityEngine. Note CityEngine is NOT a visualization tool. 90% of time working, you only generate a small portion of a city when you are changing the code or working on a specific design. So there's really no need for such GPU power. It does not make work you faster.

It's like with cars. Do you need a Maserati to go shopping ? Not really.
