$SystemID
is a short string that identifies the type of computer system on which the Wolfram System is being run.
Details

- Computer systems with the same $SystemID should be binary compatible, so that the same external programs and .mx files can be used.
- Sometimes binary compatibility may only be complete when the same version of the operating system is used.
- $SystemID is used in naming directories generated by DumpSave and wscc.
- Values for $SystemID contain only alphanumeric characters and dashes.
- Typical values are "Windows-x86-64", "MacOSX-x86-64", and "Linux-x86-64".
