Analytica User FAQs/Editions

What are different Analytica editions

The Product Editions page on the Lumina Web Site covers the different Analytica editions, both the editions for model builders and the editions for model end-users. Those are the recommended pages to find this information.

Questions beyond what is covered in those pages appear here.

What are the differences between Analytica 32-bit and Analytica 64-bit?

1. Analytica 64-bit requires a 64-bit version of Windows operating system. Most new Windows computers run 64-bit versions, but many older ones do not.
2. Analytica 32-bit, like any Windows application can access on 3GB RAM (or in a few cases 4GB depending on your OS settings) even if your computer has more. Analytica 64-bit can use as much RAM as you have plus virtual memory on your hard disk.
3. Analytica 64-bit, like most Windows applications, runs about 25% faster than 32-bit.
4. Analytica 32-bit has been discontinued starting with the 5.3 release.

What are the differences between ADE 32-bit and ADE 64-bit

The same as the differences between Analytica 32 and 64-bit listed above..

In some applications of ADE, you may have multiple ADE instantiations, each running in its own process. Each 32-bit instance is subject to the maximum of 2GB, 3GB, or 4GB, but the total memory utilization is limited only by the amount of virtual memory. So if you have 10 ADE instances running, each of those using 2GB of memory, you can actually make use of 20 GB or memory even in Analytica 32-bit.

You can use multiple instantiations of ADE to parallelize computations (usually dividing scenarios among different processes), and in Web applications where each user-session is assigned its own ADE instance.
