 To maximize the performance of Dinamica EGO execution, follow the guidelines below: To maximize the performance of Dinamica EGO execution, follow the guidelines below:
  
-  * Make sure the GUI option "​Tools ​-> Options | Advanced | Detect ​the number of processors available"​ is selected. If your are running your models using the Console Launcher Tool, make sure the "​Processors"​ option for each model is set to 0.+  * Make sure the GUI option "​Tools ​=> Options | Advanced | Automatically detect ​the number of processors available"​ is selected. If you are running your models using the Console Launcher Tool, make sure the "​Processors"​ option for each model is set to 0.
  
-  * If you have enough RAM memory, make sure the GUI option "​Tools ​-> Options | Advanced | Disable ​raster map swapping"​ is checked. On the Console Launcher Tool, check the Disable map swapping option. It will force EGO to use memory (not the hard disc) to do most calculations. It also allows the use of parallel algorithms by several operators. //Beware of [[faq#​question_p-2|memory limits]] whether you are using a Windows XP/Vista/7 32 bit SO.//+  * If you have enough RAM memory, make sure the GUI option "​Tools ​=> Options | Advanced | Disable ​the swapping ​of raster maps between hard drive and memory" is checked.

It also allows the use of parallel algorithms by several operators. //Beware of [[faq#​question_p-2|memory limits]] whether you are using a Vista/7 32-bit SO.//
  
-  * Make sure the "[[mingw_plugin|MinGW for Dinamica EGO]]" extension is installed and the GUI option "​Tools ​-> Options | Advanced | Disable native ​expression compilation" is unchecked. On the Console Launcher, uncheck "​Disable expression compilation"​.+  * Make sure the "[[plugins_4|Enhancement Plugin ​for Dinamica EGO]]" extension is installed and the GUI option "​Tools ​=> Options | Advanced | Disable ​compilation of native ​expressions" is unchecked.
  
-  * Make sure the GUI option "​Tools ​-> Options | General ​Main level" is set to Result.+  * Make sure the GUI option "​Tools ​=> Options | System ​Message log level" is set to Result. //This helps when running models with lots of loop containers like [[Repeat]], [[While]], [[For]] etc//. 
 + 
 +  * Avoid the definition of maps using [[cell type type|cell type]] "1 Bit Integer"​. This cell type saves memory, but it also has a huge negative impact in performance.

 Another way is to use the [[Workdir]] functor where you set a working directory and every Load and Save functors inside it will be relative to the directory you have set. You can use several [[Workdir]] in a the same model. See the example located in the folder ''​Examples\run_lucc_northern_mato_grosso\run_roads_with_comments_and_workdirs''​ of the Dinamica examples. Another way is to use the [[Workdir]] functor where you set a working directory and every Load and Save functors inside it will be relative to the directory you have set.

 +===== Saving Model Backups =====
 +
 +You can use the following procedure to minimize the possibility of a model loss during the development:​
 +
 +Edit "Tools => Options | General | Model Backup"​ and check "​Create backup copy of the current model script upon saving"​. Then, chose a "​Backup Folder"​ where Dinamica EGO will place all model copies. If you leave this field empty, the model copy will be placed in the same folder where the original model is being stored.
 +
 +After you configure this option, the content of any files being overwritten will be copied every time you click "​Save"​ or "Save As". If you want to restore the model to a previous state, just copy the corresponding files back from the back folder to their original location.
 +
 +===== Loading Files from Zip Files =====
 +
 +Maps, tables, lookup tables and Weights of Evidence files can be loaded from [[wp>​Zip_(file_format)|zip]] files.
 +
 +[[wp>​Zip_(file_format)|Zip]] files are useful to pack all files used by a model in a single archive. However, zipping all files does not increase the amount of data that Dinamica EGO can handle simultaneously. Behind the curtains, Dinamica unzips the files into a temporary folder and loads them from there.
 +
 +[[wp>​Zip_(file_format)|Zip]] files are also limited to 4 GBytes in Dinamica. If you use a file outside the zip archive, these files can be much bigger than that.
 +
 +To read a file located in a [[wp>​Zip_(file_format)|zip]] file, you have to use a [[Workdir]] container. Then, edit the [[Workdir]] and use the [[wp>​Zip_(file_format)|zip]] file name in the "​folder"​ input port. Place a file loader ([[Load Map]], [[Load Weights]] etc) inside the [[Workdir]] container. The file name mentioned in the file loader must match the name used by the file contained in the [[wp>​Zip_(file_format)|zip]] archive.
