'''Firefly''', formerly named '''PC GAMESS''', is an [[ab initio quantum chemistry methods|ab initio]] [[computational chemistry]] program for [[Intel]]-compatible [[x86]], [[x86-64]] [[Microprocessor|processor]]s based on [[GAMESS (US)]] sources. However, it has been mostly rewritten (60-70% of the code), especially in platform-specific parts ([[memory allocation]], disk [[input/output]], [[computer network|network]]), [[mathematic]] functions (e.g., [[Matrix (mathematics)|matrix]] operations), and [[quantum chemistry]] methods (such as [[Hartree–Fock method]], [[Møller–Plesset perturbation theory]], and [[density functional theory]]). Thus, it is significantly faster than the original GAMESS. The main maintainer of the program was Alex Granovsky. Since October 2008, the project is no longer associated with [[GAMESS (US)]] and the Firefly rename occurred. Until October 17, 2009, both names could be used, but thereafter, the package should be referred to as Firefly exclusively.<ref name="bare_url">[http://classic.chem.msu.su/gran/gamess/ Firefly Home Page]</ref>
