The x86 Open64 compiler system is a high performance, production quality code generation tool designed for high performance parallel computing workloads. The x86 Open64 environment provides the developer the essential choices when building and optimizing C, C++, and Fortran applications targeting 32-bit and 64-bit Linux platforms. The x86 Open64 compiler system offers a high level of advanced optimizations, multi-threading, and processor support that includes global optimization, vectorization, interprocedural analysis, feedback directed optimizations, loop transformations, and code generation which extracts the optimal performance from each x86 processor core. The x86 Open64 Compiler Suite simplifies and accelerates development and tuning for x86, AMD64 (AMD® x86-64 Architecture), and Intel64 (Intel® x86-64 Architecture) applications. The x86 Open64 compilers create a strong foundation for building robust, high performance parallel code through MPI, OpenMP®, and auto-parallelization along with highly optimized libraries*.

Open64 is an open source, optimizing compiler for x86-32 and x86-64 architectures as well as many other micro-architectures. It derives from the Silicon Graphics, Inc. compilers for the MIPS processor, called MIPSPro. It was released under the GNU GPL in 2000. Open64 supports C/C++ and Fortran 77/95, as well as the shared memory programming model OpenMP. The compiler can perform high-quality interprocedural analysis, data-flow analysis, data dependence analysis, and array region analysis.

Open64 leverages many aspects from the GNU Compiler Collection (GCC). Built within the Open64 framework is the gcc/g++ front-end which augments the gnu-compatibility of the Open64 compiler system. The Open64 compiler also relies on the GNU collection of binary tools (i.e. binutils) and C Library (i.e. glibc).
