64-Bit GAUSS 9.0 for Windows

64-bit GAUSS 9.0 is now available for Windows. The current version has the following limitations:

  • Command-line only, no GUI (Graphical User Interface).
  • Cannot read/write ExcelTM files directly.
  • No GAUSSplot support.
A copy of the 32-bit version will be made available (upon request) for GUI and ExcelTM functions.

The 64-bit version has two major advantages if you have a 64-bit machine.

  1. Using a 64-bit operating system gives you access to additional memory. Memory on a 32-bit machine is limited to 2^32 bytes, or 4GB. On a 64-bit machine, this number is increased to 2^64, an increase by a factor of 4 billion. More memory allows you to work with bigger matrices and solve bigger problems.

  2. The 64-bit version can run faster. With the greater memory capacity more of the symbol table remains in core memory rather than reading/writing to the swap file.
