QMASM fills a gap in the software ecosystem for D-Wave's adiabatic quantum computers by shielding the programmer from having to know system-specific hardware details while still enabling programs to be expressed at a fairly low level of abstraction. It is therefore analogous to a conventional macro assembler and can be used in much the same way: as a target either for programmers who want a great deal of control over the hardware or for compilers that implement higher-level languages.
N.B. This tool used to be called "QASM" but was renamed to avoid confusion with MIT's QASM, which is used to describe quantum circuits (a different model of quantum computation from what the D-Wave uses) and the IBM Quantum Experience's QASM language, also used for describing quantum circuits.
QMASM is written in Python and uses Setuptools for installation. Use
python setup.py installto install in the default location and
python setup.py install --prefix=/my/install/directoryto install elsewhere.
Documentation for QMASM can be found on the QMASM wiki.
