- | ^Windows 32 Bits (Vista 32, 7 32, 8 32 and 10 32) |Dinamica EGO is limited by Windows Operating System memory policies (~2 Gigabytes per process), no matter how much memory you have installed in your system. However, Dinamica is a "LargeAddressAware" application, so it is possible to increase the amount of memory used in a 32 bit arquiteture to ~3 Gigabytes following the instructions available [[ http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=9583842&linkID=9240617|here]]. //Beware that changing the Windows memory partition policy can have some unpredicted consequences.// Being a a "LargeAddressAware" application also means that the 32 bit version of Dinamica is able to handle ~4 Gigabytes when running on a 64 bit Windows Operating System.| | + | |

- | * Run Dinamica EGO 64 in a //Windows 10/8/7/Vista 64-bit// environment and add //much more// memory to your computer. Do not use a Windows 32-bit environment to run your simulations; | + | * Run Dinamica EGO in environment with as much memory as possible; |
- | * Make sure the flag Disable Raster Map Swapping in Tools|Options|Advanced is //unchecked//. If your are using the Console Launcher, you will have to edit the model configurations. Unchecking this flag degrades performance, but uses less memory; | + | * Set the memory management option ("Tools" -> "Options" | "Advanced") to "Balanced" or "Aggressive". If your are using the command line tool, you will have to use the option "-memory-allocation-policy" with values 1 or 4, respectively; |
