'''Firefly''', formerly known as 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 substantially rewritten (about 60-70% of the code), especially in platform-specific parts ([[memory allocation]], disk [[input/output]], [[computer network|network]]), [[mathematic]] functions (e.g., [[matrix operation]]s), and [[quantum chemistry|quantum chemical]] methods (such as [[Hartree&ndash;Fock]], [[Møller&ndash;Plesset perturbation theory]], and [[density functional theory]]). Therefore, it is significantly faster than the original GAMESS. The main maintainer of the program is Alex Granovsky. Since October 2008 the project is no longer associated with [[GAMESS (US)]] and the Firefly name was created. 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>
