64-bit r-code: Performance versus portability

In Release 10.1A, 32-bit r-code only runs with the 32-bit product, and 64-bit r-code only runs with the 64-bit product. This change provides performance benefits (such as very large memory) for the 64-bit product. However, it breaks the portability of r-code between 32-bit and 64-bit platforms.

If portability between platforms is more important than 64-bit performance, you can use the Release 10.1A 32-bit product, which can run Release 10.0x 32-bit and 64-bit generated r-code as well as Release 10.1A 32-bit generated r-code. The Release 10.1A 32-bit product can be installed and run on 64-bit hardware, but you will not see the performance benefits of the 64-bit product.

For more information about this change, see the section on 64-bit r-code performance in Chapter 2, " Feature Comparisons."
