There can be costs associated with changing to a 64-bit system, because data sizes can increase. With SAS 9.2 and later, 64-bit Java application servers and JREs are established as the baseline for all 64-bit hardware to leverage benefits of the larger address space and improved performance. The 64-bit environment removes the 2GB of memory limit that exists on 32-bit machines.
By moving to 64-bit SAS, you will be using software that is designed for this environment.
When you purchase new Windows-based hardware, it will contain a 64-bit CPU, or processor (圆4).
Installing the 圆4 version will allow SAS to run better on your system however it may cause compatibility issues with your SAS program. SAS 圆4 is the standard installation version. x86 refers to the 32-bit version, and 圆4 is the 64-bit version. Installation of the Admin version must be approved by UIT. There's a strict delineation between what SAS considers T&R (the user has to be directly engaged in either or both, and 'research' means academic research, not research for administrative functions) versus Admin (basically everything else that isn't teaching or academic research). CAS ITS recommends adjusting your cache to 30 GB and deleting the current cache, if problems downloading arise. SAS requires over 24 GB to be downloaded to the computer before the computer can begin installation. If you need an additional language, please contact us. Software Center only installs SAS in English.
