'''Open64''' is a [[free software|free]], [[open-source software|open-source]], optimizing [[compiler]] for the [[Itanium]] and [[x86-64]] [[microprocessor]] architectures. It derives from the [[Silicon Graphics|SGI]] compilers for the MIPS [[R10000]] processor, called ''MIPSPro''. It was initially released in 2000 as [[GNU GPL]] software under the name Pro64. The following year, University of Delaware adopted the project and renamed the compiler to Open64. It now mostly serves as a research platform for compiler and [[computer architecture]] research groups. Open64 supports [[Fortran]] 77/95 and [[C (programming language)|C]]/[[C++]], as well as the [[Shared memory (interprocess communication)|shared memory]] programming model [[OpenMP]]. It can conduct high-quality [[interprocedural optimization|interprocedural analysis]], [[data-flow analysis]], data [[dependence analysis]], and array region analysis.  Development has ceased, although other projects can use the project's source.
